The Aptina AR0521 will be launched in 2018 to be used in some dashcams. It is a 5MP CMOS and I think Aptina created it to challenge the little old but good and well sold of Omnivision OV4689 which is 4MP. Being 4MP and 5MP, both of them can record at 2K resolution.
Back a little in history, I am thinking to this: when Aptina AR0330 was used in so many cheap but OK dashcams, the OV4689 was the other chipset generally used, but latest time the OV4689 was used in more and more and better and better dashcams also because the resolution was increased so the AR0330 was left behind more and more. Then some manufacturers wanted more video quality from their dashcams and started using the Sony IMX322 and IMX323. Now the 2MP IMX from Sony is sold very well in a lot of chinese dashcams even almost no name. The chinese guys learned that just the Sony name can sell their camera.
So Aptina needs to make a move to not stay too much behind and created the 5MP sensor because the 2MP market (AR0330) is almost lost because of Sony IMX323.
Will be this a good idea for them? Will the manufacturers start using this chipset if is cheaper than a 5MP Sony IMX, even they know that the Aptina name can not sell so good as the Sony name?
I know is not correct to compare a 5MP CMOS with a 2MP CMOS which is normally better in low light, but in my comparison I will use the king of darkness situations, the Sony Starvis IMX291 and in this way to see how much is behind a 5MP CMOS which is advertising a good video in low light conditions.
I will offer here few YouTube links and in the video descriptions are included the download links for original videos which are all in this folder.
Compared to other 4-5MP CMOS Aptina claims better day image, better low light image. In these two videos you clearly see that the AR0521 managed the best the white balance situation at least for the dusk time situation:
Video comparisons during day:
Anybody can take snapshots on that videos and present their observations, their videos, I am trying to not conclude anything right now. Best is to compare the 4MP and 5MP CMOS to be fair.
Here are two very short videos with just the AR0521 during night:
Please consider that every camera has different lens, different firmwares (OV4689 was on SDK 4, IMX291 on SDK 3 and AR0521 is a beta firmware).
