AR0141CS: 1/4-Inch Digital Image Sensor
Subsampling
The sensor will increment x and y addresses in multiples of 2. This indicates that a
GreenR and Red pixel pair will be read together. As well, that the sensor will read a Gr-R
row first followed by a B-Gb row.
x subsampling factor = 1-----+------x--_---o---d---d---_---i--n---c-
2
(EQ 4)
y subsampling factor
=
1-----+------y--_---o---d---d---_---i--n---c-
2
(EQ 5)
A value of 1 is used for x_odd_inc and y_odd_inc when no pixel subsampling is indicated.
In this case, the sensor is incrementing x and y addresses by 1 + 1 so that it reads consec-
utive pixel and row pairs. To implement a 2x skip in the x direction, the x_odd_inc is set
to 3 so that the x address increment is 1+3, meaning that sensor will skip every other Gr-
R pair.

x_odd_inc
x_odd_inc = 1
skip = (1+1)*0.5 = 1x
x_odd_inc = 3
skip = (1+3)*0.5 = 2x

Restrictions
The horizontal FOV must be programmed to
meet the following rule:
x---_---a---d---d---r--x_---_e---on---dd---d-–--_---ix-n--_-c--a--+d----d-1--r--_---s--t-2-a--r--t---+-----1-- = even number

Restrictions:

Note: In skip2 the window size has to be a multiple of 4.
