AR0330: 1/3-Inch CMOS Digital Image Sensor

Frame Readout

The sensor readout begins with vertical blanking rows followed by the active rows. The

frame readout period can be defined by the number of row periods within a frame

(frame_length_lines) and the row period (line_length_pck). The sensor will read the first

vertical blanking row at the beginning of the frame period and the last active row at the

end of the row period.

Figure 39:

Example of the Sensor Output of a 2304 x 1296 Frame at 60 fps

The frame valid and line valid signals mentioned in this diagram represent internal signals within the sensor.

The SYNC codes represented in this diagram represent the HiSPi Streaming SP protocol.

Figure 39 aligns the frame integration and readout operation to the sensor output. It also

shows the sensor output using the HiSPi Streaming SP protocol. Different sensor proto-

cols will list different SYNC codes.
