Programming Restrictions When Binning and Summing

Binning and summing require different sequencing of the pixel array and impose

different timing limits on the operation of the sensor.

As a result, when xy-subsampling is enabled, some of the programming limits declared

in the parameter limit registers are no longer valid. In addition, the default values for

some of the manufacturer-specific registers need to be reprogrammed. See “Minimum

Frame Time” and "Minimum Row Time" on page 43.

Subsampling / binning options:

1. XskipYskip

R0x3040[11], x_bin_en: 0

R0x3040[13], row_sum: 0

R0x0382: x_odd_inc = 3 (xskip2) or 7 (xskip4)

R0x0386: y_odd_inc = 3 (yskip2), 7 (yskip4) or 15 (yskip8)

2. XbinYskip

R0x3040[11], x_bin_en: 1

R0x3040[13], row_sum: 0

R0x0382: x_odd_inc = 3 (xbin2)

R0x0386: y_odd_inc = 3 (yskip2), 7 (yskip4) or 15 (yskip8)

3. XskipYsum

R0x3040[11], x_bin_en: 0

R0x3040[13], row_sum: 1

R0x0382: x_odd_inc = 3 (xskip2) or 7 (xskip4)

R0x0386: y_odd_inc = 3 (ysum2)

4. XbinYsum

R0x3040[11], x_bin_en: 1

R0x3040[13], row_sum: 1

R0x0382: x_odd_inc = 3 (xbin2)

R0x0386: y_odd_inc = 3 (ysum2)

5. XsumYsum

R0x3040[11], x_bin_en: 1

R0x3040[13], row_sum: 1

R0x3EE4[0], sreg_colamp_sum2: 1

(cannot write to this bit when streaming - have to write to entire register)

R0x0382: x_odd_inc = 3 (xsum2)

R0x0386: y_odd_inc = 3 (ysum2)
