I'm considering a camera with the following specs per the manufacturer:
Image Sensor: 16.0MP full HD CMOS, manufacturer not specified
Chipset: Ambarella A7LS75
Video resolution: Full HD 1080P at 60fps/30fps, 720P at 120fps/60fps/30fps, 848 x 480 at 240fps/120fps/60fps/30fps
Image Resolution: 14M (4608x2592), 14M (4608×3072), 16M (4608 x 3456)
Per the specs these appear to be pretty good numbers for an inexpensive action cam. According to the Ambarella A7LS Product Brief http://www.ambarella.com/uploads/docs/A7LS-Brief-121713.pdf the chipset should be capable of handling the image sensor with no problems. However, does any of this actually tell me the native resolution, image size or frame rate? Although the chipset seems able to handle the image sensor, wouldn't it also depend on how the manufacturer has programmed the chipset? And does any of this tell me the frames-per-second capability without frame doubling?
Even if the camera is capable of 1080p resolution, 16MP images and 60fps without frame doubling, doesn't the output of the sensor affect quality? Isn't the sensor the thing that converts light waves into ones and zeros so its ability to do this accurately affects image quality?
I sometimes see that bitrates have a bearing on video quality, generally the higher the better. Is the bitrate a function of the sensor or chipset or are there other internal components that would affect this?
Another question would be the lens. While I presume it generally affects the image quality does it also limit any other parameters? For example, even though an image sensor is capable of 16MP, does the lens configuration actually cast an image size that takes advantage of the full surface area of the sensor?
Does image stabilization limit resolution or frame rates? Beyond its stabilization function, does it affect video or still image quality in other ways?
There's also the question of the transfer of files to devices outside the camera itself. The camera could have all the right specs internally but we shoot videos and pics to view on smart devices, TV's and computer monitors. Output must comply with industry standards in order to be compatible with other devices but what about the quality of the output? Do internal components besides the chipset affect the quality of the output? For example, what about the Wi-Fi transmitter? Any others?
If you pass this quiz you get an A+ grade!!!
