Looking for Image Signal processor that supports >10MP CMOS image sensor..

Hi,

Thanks...

--- Quote ---I think NiHaoMike was asking whether your camera is meant to support different modes -- a "full resolution" mode with 10 MP but slower frame rate, and a "fast mode" with 60 FPS but limited resolution. Or do you actually intend to capture 10 MP images at 60 FPS, which would be quite a challenge?

My image sensor's max resolution is 3840 (H) × 2160 (V) which is 8.3 MP and it says that 60 fps at the max resolution. I don't see anything like the "fast mode" with low resolution in the specification...
 
Should my ISP be capable to receive all 60fps without missing?... I mean that I should have an ISP which supports >=60fps at 3840 x 2160 - equals to 4K.

Please correct me if I am wrong...
NiHaoMike:
So you have an image sensor that is fairly high spec, but is such that common smartphone SoCs cannot directly interface with it? If there's no SoC/ASIC to interface with it, a FPGA is pretty much the only answer. Are you planning to record the video locally or send it to some remote system in real time?

Hi NiHaoMike,

Thanks. Though the Soc we are using has ISP, its performance is very poor. That is why we had to go with an external ISP. Have you seen any FPGA based ISP that well suits for our requirements?... If yes, please share with me. It will be a starting point...



Thanks,
Sangar
NiHaoMike:
Then you probably want a faster SoC. Without knowing the system requirements, it's hard to recommend one but handling 4K60 encoding in real time is not that exotic. (More than that is, however.)

A FPGA is just a "digital breadboard on a chip", it's up to software to program it to do what you want. Modern ones have hard DSP blocks that allow them to be competitive with dedicated DSPs. (If you can also make good use of the programmable logic, that is - there's a reason why dedicated DSPs are still being made.)


I still think a faster SoC is the way to go. One possible exception is if you're going for extremely low latency (e.g. a microscope that outputs HDMI), something FPGAs excel at.

Maybe, I did not express myself correctly for the above...

I was asking for an IP for ISP from vendor like silicon image, which can put in FPGA...

Thanks,
