Camera

The X, like the EVO and Incredible, packs an 8 megapixel Omnivision camera SoC, most likely the OmniVision OV8810 (same as the EVO and Incredible) with 1.4 µm square pixels. This sensor has a reported sensitivity of 650 mV/lux-sec, and is likewise backside illuminated. For comparison, the iPhone 4’s 5 megapixel OV5650 SoC has a sensitivity of 1300 mV/lux-sec and pixel sizes 1.75 µm square.


OV8810 - The Sensor in X, Incredible, and EVO 4G

Sensitivity in this case refers to just how much voltage a pixel creates per 1 lux-sec (one lux of light for one second) of exposure. Thus, more voltage is better and results in higher SNR, and less noise on the image.

If you recall back to our iPhone 4 piece, I talked a lot about why backside illumination is relevant as pixel sizes continue to shrink. Quantum efficiency (sensitivity) is one critical reason, but the other is quantum blurring negatively affecting image contrast (MTF). If you’re interested, you can read more here.

Camera Interface

Details of the camera SoC aside, the X foregoes the typical Android camera interface and instead brings its own. It’s different than the one used on the original Droid, and not like HTC’s interface.

On the right are some quick access buttons for scenes, effects, flash, and switching to video. Press menu, and you’ll get picture modes, tags, and settings. Confused yet as to what the difference between scenes, effects, and modes are?

Scenes allows you to set some quick shooting scenarios that the camera will hopefully adjust for. There’s auto, portrait, landcape, sport, night portrait, sunset, macro, and steady shot. I left the camera on auto for all of the test shots. Effects lets you apply filters to the images, such as black and white, negative, sepia, solarize, red green or blue tint, or normal if you’re feeling generic. Flash as expected comes with auto, on, and off modes.

Camera Settings

In the top left, you can tap on a tag symbol and toggle GPS assisted location tagging, or custom tags. Hit up settings, and you can change the picture resolution between full 8 MP, 6 MP widescreen, 5 MP medium, and small 3 or 2 MP presets. There also are settings for ISO equivalent sensitivity and exposure. The camera also promises face detection for autofocus, more on that later. The volume buttons control digital zoom.

I mentioned earlier that the X got an OTA update about midway through my time with it. One of the things it addressed was a camera complaint I had begun documenting but is obviously irrelevant now. Before the OTA update, the image preview was higher resolution, but white balance and other color correction effects didn’t show up in the live preview. In effect, the snapped photo was often an entirely different temperature, and looked entirely different. Since the update, Motorola has made the live preview accurately reflect the color temperature of the captured photo, at the cost of a sizable chunk of resolution.

It’s hard to describe how the preview looks now, but it’s no longer of native resolution on the screen, instead appearing slightly blurry and of lower resolution. Viewing the captured photo shows the native quality, but the preview and live view aren’t how the used to be. I took side by side photos of the same subject with an EVO, but even there it's difficult to really see how much the preview differs - either way, it's there. It just doesn't look as good.

Camera launch is between 3-4 seconds now, another of the things the OTA update addressed. It’s relatively speedy but not instantaneous, though none of the smartphone camera launches are. Motorola again uses a colored, two-position dedicated button for shutter control.

    I'm actually going to dump all the screen comparison photos I've got (there are quite a few) into a gallery, then you can peruse at native resolution. Should be up in a little bit ;)

    Fantastic review but I expect no less from AnandTech. But there are a couple of bloopers:

    1- OMAP 3630 is third mobile chip to use 45nm process. First is of course A4. But second is Samsung's Hummingbird, a chip that the korean company designed with help of Intrinsity. This chip is found in Galaxy S or its variants. Samsung is the same company that also tweaked A4, which incidentally is fabbed by Samsung. Too many coincidences ;-)

    2- A comparison to PowerVR SGX 540 found on Galaxy S would have been interesting as according to Samsung SGX 540 is almost three times more powerful than SGX535.

    3- Droid X should have also been compared with Galaxy S or any of its variants like Captivate, Vibrant etc

    This line: Samsung is the same company that also tweaked A4, which incidentally is fabbed by Samsung

    Should read: Intrinsity is the same company that also tweaked A4, which incidentally is fabbed by Samsung

    Does AT have any plans to review any of the Galaxy S phones? I just picked up a Captivate on Sunday and I'd love to see how it stacks up. I just ran the Neocore benchmark and got around 55 FPS, which speaks well of the GPU, but I'd like to see results from the other tests you guys do. Reply

    Hey Goty,

    We definitely have plans to do reviews of all of the Galaxy S phones we can get our hands on. I'm working on getting them as soon as possible ;)

    I'm also pretty excited to explore that SoC and compare.

    Really enjoyed this review. Keep up the great work! Being as thorough as you guys are really helps to make good decisions on purchases. Reply

    lol how long before we can attach an external mouse and keyboard to a phone to use it as a pc and play 3d games online with it Reply

    How about this?

    Guys, another gold standard review. I may not be able to pick up an X because I'm still under contract with another carrier, but the reviews are riveting. Keep up the excellent work! Reply
