So I thought I’d post an update on my camera experiences and my conclusions so far - like most people I’ve had some issues with some aspects - and have been struggling to make it practical to use. Very simply I’m still getting ongoing issues with laggy slow shutter speeds, which I can only resolve fully by reducing image capture to 5MP (instead of 50MP). Also when taking 50MP images I’m also still getting variability of image quality that I can’t resolve (largely fine if outdoors in bright sunlight, everywhere else it’s not so good).
In the BraX3 phone specs for the cameras it states the Front Camera is 5MP with a GC05A2 CMOS sensor, but then for the Main Back Camera it states it is 50MP with the same GC05A2 CMOS sensor. That doesn’t make sense, unless there is a typo (which seems unlikely but is possible), because how can the same sensor be 2 radically different resolutions.
If you search this model on the web (another example, and it’s even on Amazon if you search hard enough); basically you’ll find it everywhere. And always as a 5MP sensor, sold as a low cost camera for phones, similar devices and drones - and always with more or less identical spec info. Nowhere does it appear listed as a higher resolution (at least that I could find). And I would not expect a CMOS sensor to have 2 different resolutions with the same model or part number.
Perhaps @plamen could step in here and comment or clarify - and verify it’s not a typo and the sensor models are the same (and/or are they missing a prefix or suffix to the model ID)? Or what the correct CMOS sensor model actually is if it’s a typo?
Otherwise, if it is the same sensor for both, one is then left wondering if some sort of upsampling or something is happening at image capture time on the BraX3; which could explain the lagginess of the image capture, and the variability of the image quality at 50MP? Otherwise I simply don’t understand how the same CMOS sensor can be 5MP in the front camera and yet 50MP in the rear one?
