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

Image Data Output Interface

4. If the sensor is reset, any frame in progress is aborted immediately and the MIPI sig-

nals switch to indicate the ULPS.

5. If the sensor is taken out of the streaming system state and reset_register[4] = 1

(standby end-of-frame), any frame in progress is completed and the MIPI signals

switch to indicate the ULPS.

If the sensor is taken out of the streaming system state and reset_register[4] = 0 (standby

end-of-frame), any frame in progress is aborted as follows:

1. Any long packet in transmission is completed.

2. The end of frame short packet is transmitted.

After the frame has been aborted, the MIPI signals switch to indicate the ULPS.

Uncompressed Bayer Bypass Output

Raw or processed 10-bit Bayer data from the sensor core can be output in bypass mode

by:

1. Using both DOUT[7:0] and DOUT_LSB[1:0].

2. Using only DOUT[7:0] with a special 8 + 2 data format, shown in Table 10.

Readout Order

The sensor core supports different readout options to modify the image before it is sent

to the host system. The readout can be limited to a specific window size of the original

pixel array.

By changing the readout directions, the image can be flipped in the vertical direction

and/or mirrored in the horizontal direction.

The image output size is set by programming row and column start and end address

variables.

When the sensor is configured to mirror the image horizontally, the order of pixel

readout within a row is reversed, so that readout starts from the last column address and

ends at the first column address. Figure 14 shows a sequence of 3 pixels being read out

with normal readout and reverse readout (Bayer8 + 2 mode shown).
