How to expand the capabilities of the camera smartphone running Android - Computerra-Online

A lot of interesting plot

pictures today is not lifted professional technique, and smartphones. In contrast to the “reflex” or “Soap”, the phone is always with you. He’s already turned on and ready to go at any time. It was built in camera have time to take all the fun – from the first steps of a child before the fall of the meteorite. Initially, her photographic opportunities are very limited, but there are ways to significantly expand them using freeware tools and small layfhakov.

main problem when shooting a smartphone – a hand shake. Almost always the frames are obtained in varying degrees of blurry. The camera is easy to install on a tripod, but what about your smartphone?

Secure smartphone by using a cradle, branded and compatible derzhalok. Sale and miniature tripod, but if you look for these specific things once, you can do homebrew of the more common items.

Alternatively, you will need a regular tripod, stationery clamp nut and the corresponding diameter. Cap will be more convenient, as his hands tightened. Most tripods thread 3/8 “. The thread pitch on the nut a little not the same, but you can fix it without a problem. To avoid scratching the screen, beneath the foot clamp a piece of paper.

Most of the controls will be located along the long sides of the screen, so it is recommended to strengthen the smartphone for the short side. Once the desired angle is selected, proceed to the software part.

Camera FV-5 (Lite)

This program will be of interest to those who are used to complete control. She carries the maximum interface and logic with the “reflex” on the smartphone screen, offering an array of additional features, even in bypass restrictions Camera Driver OC Android.

The first thing that catches the eye – the full display of all the shooting settings. The sensitivity value in units of ISO, shutter speed and aperture, such as focusing and metering, manual exposure compensation within six stages, the ability to lock it automatically determining and fixing the selected white balance settings. And all this is only the visible part of the iceberg.

are four preset white balance settings plus its automatic detection and fixing.

Metering is selected from three options: Evaluative, Partial, and Spot. The first is the default. The second mode is mainly required for shooting against the light to make the foreground brighter. Otherwise, the picture on the background of the window will remotely resemble the silhouette genre. The third option is used in tricky lighting conditions, when the frame is flashing (overexposure) and deep shadows, and to calculate the exposure is enough for any one object.

Additionally, you can set the constant exposure compensation: simply slide the slider to get the desired result. All changes are displayed on the screen at once. If you want to make a series of frames with precisely defined exposure, it will block the re-determination by pressing the AE-L.

In addition to the usual

shooting information on the sidebar there is a shortcut key to a rare and fine tuning. Encoding settings not only allow you to set the compression of JPEG, but also choose to save the PNG format without loss. Among the facilities the Picture note sharpness. It is reduced to 2-3 or disable altogether, as add field during postprocessing can be neater and more difficult to eliminate the excess.

After setting the viewfinder can be set to display the histogram and its type, to establish an always-on mode screen, select one of the nine grids crop, or remove it altogether.

In the “General Settings” interest is the option to “focus before shooting.” Additional correction AF after pressing the shutter release significantly increases the quality by eliminating lubrication caused by shaking your smartphone. This is especially true for models without a hardware shutter button, which is necessary to press on the screen.

You can also change the volume of the error alarm, auto focus and a successful focus, adjust the shutter sound imitation and completely turn off all sounds. The latter is especially useful if you do not want to attract attention.

In some models of smartphones camera sound off transfer device to silent mode. In others, it always work force, and to remove it you have to gain root and deleting the corresponding sound file.

camera driver in the operating system Android limits the maximum shutter speed at 1/2 seconds. So fans of nocturnal species technically can not shoot in this genre regular means. Authors Camera FV-5 came up with his solution to the problem.

Slow shutter speeds to bypass restrictions camera driver in the operating system Android.

When you press the [P] -> [S] brings up a menu where you can set the shutter speed slower and arbitrary values. This mode is implemented by intercepting the signal and the Live View also has its limitations. Because the image was originally intended only for quick framing, it has a lower resolution and uses only part of the elements of the matrix. Depending on the manufacturer of the chamber and installed OS, it can be 0.3, 1.3 or 2.1 megapixels. Available options are also displayed in the settings.


Fujifilm introduced the matrix EXR CMOS, many objected to the new regime of low-light shooting. In the terminology of it is called SN (high sensitivity) and Pixel Fusion. Sense of the idea is to eliminate blur and improve image quality, sacrificing his (usually redundant) resolution. Adjacent pixels that register the same color, programmatically grouped together. For example, if two pixels treated as one, the shutter speed can be cut in half for the same value of ISO, but instead will turn 16 megapixel 8 megapixel.

tried to create a similar algorithm for built-in cameras and smartphones, but not very good at it. The fact that BSI CMOS has significant architectural differences from EXR CMOS, and without hardware support, so cunningly collect light from adjacent pixels useless.

Still something remotely similar we are seeing in Camera FV-5 when you enter a positive exposure compensation at the maximum ISO. Luminance noise turns predictably a lot, but often it is generally the only way to make a picture in semi-darkness. Full-time program can not cope in a more favorable environment. In those rare situations where there is enough light, you can manually set the minimum value of ISO (100) and get a clean shot.

smartphone camera often fails to detect exposure. Correct this deficiency will help auto bracketing exposure to your settings (“fork” from 3 – 7 frames). When photographing people simply choose the one most successfully arranged. If you’re shooting a landscape or architecture, then these images can then take a picture with an extended range of brightness (HDR).

Professional photographers often shoot a series of shots to watch an interesting face or a good perspective of the model. For a smartphone continuous shooting is not the most effective choice, but children playing or posing a group, it makes sense to shoot that way.

If you could still fix your smartphone, try to shoot the timer mode or time-lapse photography (timelapse). The first option is useful for self-portraits, group shots, or just more precise shots, because it eliminates the shaking during the descent.

lapse photography allows you to effectively capture the slow processes. Traditionally, it is used to capture the drop-down colors of the sky, atmospheric phenomena and demonstrate the changing time of day – see the example below.

Perhaps a separate application Time Lapse Creator someone seems more comfortable. However Camera FV-5 attracts exactly versatility. All functions are implemented in it as carefully as possible, and not to the detriment of others. Big Ball of Mud lies in the limitations of the free version. Maximum image resolution is 640 × 480, but the program is otherwise fully functional.

Camera MX

This program stands out among the more simple applications to capture smartphone. It attracts the ability to store geo-metadata in the image (EXIF). With their help, you can always easy to determine when and where each picture was taken.

There is a button at the bottom right entrance of the gallery images. By default, opens the last frame, the settings of which there can also change the icon on the brush.

If you’re not watching and post-processing, and want to get an interesting result at once, look for a library of special effects. They apply even before you click the “descent”. There is a box, overlays and stylized lomo camera. Some of them are available only in the paid version of the program.

Among the most useful effect can be called a pencil sketch. Such images are ideal for technical purposes and replace sketches.

As with most other alternative programs for photography, the function of the shutter button can be assigned to the volume keys. Scaling is a characteristic stretching motion with two fingers on the screen. However, much point in it, because the cameras are not capable smartphones change the focal length (single prototypes do not count). Zooming is as simple as framing, which can be done, and after the shooting.

Analysis of prospects. Android-camera Samsung Galaxy S4 Zoom -

A & # x43D; prospects of Aliz , willows. Android-camera Samsung Galaxy S4 Zoom Library: analytics In 2012, the irrepressible Samsung released a new segment of cameras running on Android. Samsung Galaxy Camera was not a bestseller, but a notable decision. After analyzing the perception of devices from buyers in the current marketing year, the company presented a new vision smartkamery, aiming at the mass segment … So there was a Samsung Galaxy S4 Zoom. In the first block of the material we consider the strengths and capabilities of the device, in the second – his weaknesses and risks.

Strengths and Opportunities

1. It is not necessary to be a professional from the world of digital gadgets to understand that if the device is left in the line of Galaxy S and especially the flagship Galaxy S4, the company Samsung believes in it and makes it very tall bets. If the Galaxy Camera was created in order to test the niche, Galaxy S4 Zoom – full device aimed at actual sales, rather than creating WOW-effect. Thus, the conceptual component has changed: instead of a camera with a smartphone interface in front of us with a smartphone photofraction from full photographic device. The fact that perhaps in ten years rolled on the exhibitions as a concept or sold exclusively in Korea and Japan (namely the phone with a retractable lens), and finally became a reality.

2. Any “Samsung” designer Samsung Galaxy S3 / S4 – this is the application for the love of buyers. Galaxy S4 Zoom stars from the sky is not enough: the front side, it is the real Galaxy S4 – high gloss finish and no surprises. Many swear and resent the plastic, but time Samsung has not yet moved to the metal, then realizes that it is possible to maintain the popularity and without it. All the same enthusiasm from the audience will fall to the back surface, which is made exactly like a real camera, with a large window flash, the shutter release button and, of course, zumiruyuschim lens.

3. It’s nice that compared with Samsung Galaxy Camera , the novelty has become much thinner, lighter and smaller. No, it still has impressive size, but has now become more like a smartphone on this parameter. Compare: 63.5×125.5×15.4 mm, 208 grams, at the Galaxy S4 Zoom and 70,8 × 128,7 × 19,1 mm, 300 grams, at the Galaxy Camera.

4. functional gadget – a typical representative of the middle class in understanding the Samsung. If you do not touch photofraction, it is highly popular Galaxy S mini 4 free slots for two SIM cards and other processor. 4.3-inch screen – the size is the same as in the Galaxy S 4 Mini, made by technology SuperAMOLED. “Amoled” here is quality, no raises no objections. Slot for cards microSD, 8GB of internal memory. Not without Wi-Fi, Bluetooth, GPS. Device operates on the basis of 1.5 GHz processor. Battery, thank goodness, a decent capacity – 2300 mAh.

5. The most important thing – the photographic characteristics – went from Galaxy Camera, with the exception of the zoom, and the poor will not name them: 16.3 megapixel, 1/2.3 “BSI CMOS sensor, F2.8 23mm, 10x zoom, ISO 100 to 3200, video recording in FullHD. These numbers do not disappoint, though, I think it is better not to give the Galaxy Camera in the hands of a professional photographer. About chips cameras say the words of the press release. Fast and ultra-sensitive 16-megapixel CMOS-matrix backlit (BSI) can shoot with the correct exposure with less light and faster focus than conventional matrix. Therefore, even in low-light conditions your pictures will be relatively bright. Next Samsung Galaxy S4 Zoom has a built-in optical image stabilization, which allows you to accurately focus on the subject, even if you move. Of course, there were dozens of shooting modes, various settings and excellent video (1080p at 30 fps and 720 at 60 fps).

6. The lack of competitors. In fact, with today fotoresheniyami indulges only Nokia, but yeah, that’s more marketing than the actual synthesis of “adult” camera and smartphone. Besides Nokia 808 Pure View – a model of the previous generation, and start selling Lumia 1020 still waiting.

7. Rarely is that of the cost, described in the “strengths” model, in the case of the Galaxy S4 Zoom this moment has come. 19 990 rubles – as much as asking for the Galaxy S4 mini, which has become a donor non-photographic filling fotosmartfona, both new on the 5000 cheaper Samsung Galaxy Camera at the start. Given the uniqueness of solutions, the price tag came curious: Samsung really dreaming about the popularity of the gadget, otherwise I would ask him thirty of that Nokia is going to do with my Lumia 1020.

8. We all know how much attention was given to marketing, Samsung promote their products. Moreover, we know how aggressive it is promoting the flagship and unique solutions. In the case of the Galaxy S4 Zoom support for active than for the Galaxy Camera, even a cool movie on television, it is not possible for niche devices. Well, no Galaxy S4 Zoom is not a niche, but a real fotosmartfon, founder of the segment of high-grade fotosmartfonov, another know-how of the Korean manufacturer.

Weaknesses and threats / risks

1. The main problem Samsung Galaxy S 4 Zoom – its massiveness. Engineers minimized the matrix as they could – as you read above, it came out much smaller than the Galaxy Camera. Unfortunately, the “compact” does not mean “compact”. World unaccustomed to thick sets, closing their eyes to the width and length planshetofonov: when using the Samsung Galaxy S4 Zoom you still will not leave feeling that you are holding the camera. Of course, get used to it, of course, love, but in a pocket of jeans is a 208-gram miracle did not revile.

2. Before us is a controversial product, even more massive than its predecessor. It seems that for Samsung, this niche is much more complex than, for example, the segment planshetofonov. How to convince people that the photo module, built on the same Galaxy S4 mini, enough for everyday shooting? How to get them to wear such a whopper with you? In terms of marketing, I would have emphasized the video: last year, broke service Twitter Vine, a couple of months ago, appeared in the video “instagrame.” Video content is becoming a key social networks and Galaxy S4 Zoom – an opportunity to show your friends a high quality, clear, expressive clip, seasoned with its stunning wilted.

3. Alas, the camera features compared Galaxy Camera with deteriorated zoom out, which is kind of like the main visual “chip” devices. Do not be upset: Other characteristics are preserved. Overall survey will please fans who enjoyed the “soap box” for 5000 rubles and cheaper, all the others who have dealt with the devices harder, it is not impressed. Sophisticated job Macro Zoom Yes – that’s what a pleasant surprise. I guess I should wait a couple of years as long as no one dares to tell the “but” in the address of the camera, built-in fotosmartfon. Until this time has come.

You will fall off 20 rubles for it? Imo even here there is no difference, 20 or 30

[30.08.2013 17:08:15] Author: Anton
25 price tag (read 30) for the “middle class” …

Written in “Weaknesses and threats / risks” – is complete refutation written above in the “Strengths and Opportunities”))

And not “good cool camera,” and “nice cool” smartphone price tag of 25 (ie 30) for the “middle class” … can be a long review, “who will buy it and why” and “what moves Samsung’s marketing department has taken to this”))

Previous same was kind of like a smartphone, but just a camera / PDA, or I wrong?
