AR0135CS
• 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.
