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

Image Data Output Interface

Figure 14:

Three Pixels in Normal and Column Mirror Readout Mode

When the sensor is configured to flip the image vertically, the order in which pixel rows

are read out is reversed, so that row readout starts from the last row address and ends at

the first row address. Figure 15 on page 20 shows a sequence of 6 rows being read out

with normal readout and reverse readout.

Figure 15:

Six Rows in Normal and Row Mirror Readout Mode

The AR0260 sensor core supports subsampling with skipping to increase the frame rate.

The proper image output size and cropped size must be programmed before enabling

subsampling mode. Figure 16 shows Bayer 8 + 2 readout with 2X skipping.
