AP0100CS HDR: Image Signal Processor (ISP)

Flicker Avoidance

Manual Mode

Manual mode is intended to allow simple manual exposure and white balance control

by the host. The host needs to set the CAM_AET_EXPOSURE_TIME_MS, CAM_AET_EX-

POSURE_GAIN and CAM_AWB_COLOR_TEMPERATURE controls, the camera will

calculate the appropriate integration times and gains.

Host Controlled

The Host Controlled mode is intended to give the host full control over exposure and

gains

Flicker Avoidance

Flicker occurs when the integration time is not an integer multiple of the period of the

light intensity. The AP0100CS can be programmed to avoid flicker for 50 or 60 Hertz. For

integration times below the light intensity period (10ms for 50Hz environment), flicker

cannot be avoided. The AP0100CS supports an indoor AE mode, that will ensure flicker-

free operation.

Flicker Detection

The AP0100CS supports flicker detection, the algorithm is designed only to detect a

50Hz or 60Hz flicker source.

Output Formatting

The pixel output data in AP0100CS will be transmitted as an 8/10 bit word over one or

two clocks.

Uncompressed YCbCr Data Ordering

The AP0100CS supports swapping YCbCr mode, as illustrated in Table 11.

The data ordering for the YCbCr output modes for AP0100CS are shown in Table 12:
