Register Description
Chip version. Read-only.
The first row to be read out (not counting any dark rows
that may be read). To move the image window, set this
register to the starting “Y” value. Setting a value less than
eight is not recommended, as the dark rows should be read
using Reg0x22.
The first column to be read out (not counting dark columns
that may be read). To move the image window, set this
register to the starting “X” value. Setting a value below
Reg0x18 is not recommended, as readout of dark columns
should be controlled by Reg0x22.
Number of rows in the image to be read out (not counting
any dark rows or border rows that may be read). The
minimum supported value is 2.
Number of columns in the image to be read out (not
counting any dark columns or border columns that may be
read). The minimum supported value is 9.
Number of blank columns in a row when context B is
selected (Reg0xC8[0] = 1). The extra columns are added at
the beginning of a row. See “Minimum Horizontal
Blanking” on page 35.
Number of blank rows in a frame when context B is selected
(Reg0xC8[1] = 1). The minimum supported value is (6 +
Reg0x22[2:0]). The actual vertical blanking time can be
controlled by the shutter width (Reg0x9). See “Output Data
Timing (Default Mode)” on page 11.
Number of blank columns in a row when context A is
selected (Reg0xC8[0] = 0). The extra columns are added at
the beginning of a row. See “Minimum Horizontal
Blanking” on page 35.
Number of blank rows in a frame when context A is chosen
(Reg0xC8[1] = 1). The minimum supported value is (6 +
Reg0x22[2:0]). The actual vertical blanking time can be
controlled by the shutter width (Reg0x9). See “Output Data
Timing (Default Mode)” on page 11.
Integration time in number of rows. The integration time is
also influenced by the shutter delay (Reg0x0C) and the
overhead time.
