TDA4VM: Support for RGB-IR sensor (4x4 pattern)

Part Number: TDA4VM

Hello,

Our customer wants to use RGB-IR image sensor (4x4 pattern). I understand TDA4 ISP natively supports only 2x2 CFA, but what I want to know is what kind of support TDA4 can provide for 4x4 CFA:

  • Should the complete RGB debayering process be done on C66x or ISP can handle at least part of the processing? If ISP can be used to offload part of the pixel processing, please explain us the details how it should be used.
  • Currently there is some kernel for RGB-IR processing inside PSDK, but the source is not available, can you share the source files?
  • Also, is it expected that one C66x can handle such pixel intensive task for 30 fps (2 MP) video stream?

Best Regards,

Stefan.
