PROCESSOR-SDK-DRA8X-TDA4X: Bypass CFA

RINKU WILSON

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hi,

I would like to bypass CFA in VISS for my image.

I have seen a bypass flag in CFA parameters (cfaCfg->bypass[cnt]). Is it possible to bypass demosacing by setting this to TRUE for cnt=0:3?

Hi Rinku,

Why do you want to bypass CFA? CFA is main functionality in ISP..

Hi Brijesh,

My image is an IR only image for which I would like to skip any interpolation due to demosaicing.

Hi Rinku,

But what is the processing you are using in ISP for IR only image?

Hi Brijesh,

I would like to use blocks like, DPC, LSC, NSF4, GLBCE, EE, LDC.

Hi Rinku,

Can you please go through these modules and see if they can be used for IR pixels? I guess your pixel contains just single IR values and modules can support 2x2 format. So please check first which of these modules can be used.

Hi Brijesh,

All the blocks mentioned are feasible for IR pixels. My only concern is that I want to avoid any interpolations happening inside CFA, as the IR data is already proper. Is there any provision to bypass CFA? What exactly bypass flag in CFA config is doing?

Hi Rinku,

I would suggest to go through the TRM to understand how this flag works.
