AR0260: 1/6-Inch 1080P High-Definition (HD) Digital Image Sensor

Analog Gain

Minimum Frame Time

The minimum number of rows in the image is 2, so min_frame_length_lines will always

equal (min_frame_blanking_lines + 2).

Integration Time

The integration (exposure) time of the AR0260 is controlled by the fine_integration_time

and coarse_integration_time registers.

The actual integration time is given by:

(EQ 4)

The limits for the coarse integration time are defined by:

coarse_integration_time > 0

(EQ 5)

The limits for the fine integration time are defined by:

fine_integration_time_min < fine_integration_time < (line_length_pck –

(EQ 6)

fine_integration_time_max_margin)

Fine Integration Time Limits

The limits for the fine_integration_time can be found from fine_integration_time_min

and fine_integration_time_max_margin. Values for different mode combinations are

shown in Table 14.
