PROCESSOR-SDK-AM62A: DCC debugging tool to debug related problems

1.Auto Exposure

get_imx390_ae_dyn_params (IssAeDynamicParams * p_ae_dynPrms)
{
int32_t status = -1;
uint8_t count = 0;

g_return_val_if_fail (p_ae_dynPrms, status);

p_ae_dynPrms->targetBrightnessRange.min = 40;
p_ae_dynPrms->targetBrightnessRange.max = 50;
p_ae_dynPrms->targetBrightness = 45;
p_ae_dynPrms->threshold = 1;
p_ae_dynPrms->enableBlc = 1;
p_ae_dynPrms->exposureTimeStepSize = 1;

p_ae_dynPrms->exposureTimeRange[count].min = 100;
p_ae_dynPrms->exposureTimeRange[count].max = 33333;
p_ae_dynPrms->analogGainRange[count].min = 1024;
p_ae_dynPrms->analogGainRange[count].max = 8192;
p_ae_dynPrms->digitalGainRange[count].min = 256;
p_ae_dynPrms->digitalGainRange[count].max = 256;
count++;

p_ae_dynPrms->numAeDynParams = count;
status = 0;
return status;
}

Issue:

i、There is only one set of targetbrightness, is the targetbrightness the same in different time scenarios reasonable?

ii、If 60FPS is required, what should be the exposure time? How is the maximum and minimum exposure time determined?

2.Color depth supported by DCC

Issue:

i、DCC userguide Only the raw10 and raw12 images can be used for debugging？

ii、The current DCC tuning tool color depth can be selected 10/12/14/16bits per pixel, is 14/16bit raw image can also be used for debugging?

For real applications, AE target could possibly vary, but that seems rare as far as I know.

It depends on the application requirements and sensor.
For 60fps, the maximum exposure time can be up to 16.66ms.

I am not sure what you mean by debugging here.

Most tuning tool plugins may support up to 16-bit input raw images.

Thanks for your response.

For the problem of Color depth, For example, when using 16bit raw plug_ins AWB operation, A pop-up window prompts:

“WARNING:This image is overexposed.You may get wrong tuning valuss.Consider discarding this image and capturing it again with different setting.

Thanks

Are your 16-bit raw images coming output your sensor directly?

Is your sensor output in 16-bit linear format to AM62A?
