TDA4VL-Q1: how the vpac process the ox03c10 12bit (PWL) combined HDR (4 captures)

Part Number: TDA4VL-Q1

Tool/software:

ti expert，

For the 0x03c10 cmos sensor, it outputs a combination of 20/16/14/12-bit (PWL) HDR (4-capture)

Question 1:

How does vpac handle the image frames output by the ox03c10 combined HDR (4-capture)? Will it check long exposure frames, medium exposure frames, and short exposure frames?
Please tell us the detailed process of how the vpac module processes the image frames output by the x03c10 combined HDR (4-capture)?

Question 2:

ti sensor driver interface
.setAeParams = ox03c10_SetAeParams,

static int32_t ox03c10_SetAeParams(void *pSensorHdl, uint32_t chId, IssSensor_ExposureParams *pExpPrms)

max support three frame exposure (long exposure, middle exposure, short exposure) how do support the sensor four frame exposure (long exposure, middle exposure, short exposure, very short exposure) ?

please help us , Thank you very much！！

Best regards!

Galvin

    We typically use sensor's 12-bit companded output format, e.g., 12-bit raw image --> VISS --> 8-bit YUV.
    VPAC does not check any individual exposure frame.

    This is part of your x3c sensor driver.
    OVT will give you some advice on sensor exposure settings.
