• Reset

The AR0135CS may be reset by a register write, or by

a dedicated input pin.

• Output Enable

The AR0135CS output pins may be tri-stated using

a dedicated output enable pin.

• Temperature Sensor

The temperature sensor is only guaranteed to be

functional when the AR0135CS is initially powered-up

or is reset at temperatures at or above 0

°C.

• Black Level Correction

• Row Noise Correction

• Column Correction

• Test Patterns

Several test patterns may be enabled for debug

purposes. These include a solid color, color bar, fade to

grey, and a walking 1s test pattern.

PIXEL DATA FORMAT

Pixel Array Structure

The AR0135CS pixel array is configured as 1412 columns

by 1028 rows, (see Figure 2). The dark pixels are optically

black and are used internally to monitor black level. Of the

right 108 columns, 64 are dark pixels used for row noise

correction. Of the top 24 rows of pixels, 12 of the dark rows

are used for black level correction. There are 1288 columns

by 972 rows of optically active pixels that can be readable.

While the sensor’s format is 1280

× 960, the additional

active columns and active rows are included for use when

horizontal or vertical mirrored readout is enabled, to allow

readout to start on the same pixel. The active area is

surrounded with optically transparent dummy pixels to

improve image uniformity within the active area. Not all

dummy pixels or barrier pixels can be read out. The optical

center of the readable active pixels can be found between

X_ADDR 643 and 644, and between Y_ADDR 485 and

486.
