Pixel Integration Control
These registers (along with the Window Size and Blanking registers) control the integration time for the pixels.
0x09
0-11
Number of rows of integration, default = 0x01FC (508).
0x0C
0-9
Reset delay, default = 0x0000 (0). This is the number of master clocks x 4 that the timing and control
logic waits before asserting the reset for a given row.
Pixel Clock Speed
0x0A
4-0
This register determines the pixel data rate, default = 0x0000 (0). Pixel clock period = 2 master clocks
+ [Reg0x0A, bits (4-0)]. The pixel clock out can be shifted relative to the data out by setting bit 8-11 of
Reg0x07 appropriately. Maximum value for 0x0A = 0x0015.
Frame Restart
0x0B
0
Setting bit 0 to “1” of Reg0x0B will cause the sensor to abandon the readout of the current frame
and restart from the first row. This register automatically resets itself to 0x0000 after the frame
restart. The first frame after this event is considered to be a "bad frame" (see description for
Reg0x20, bit 0).
Reset (Soft)
0x0D
0
This register is used to reset the sensor to its default, power-up state. To reset the MT9V011, first
write a “1” into bit 0 of this register to put the MT9V011 in reset mode, then write a “0” into bit 0 to
resume operation.
Zoom Mode / True Decimation Mode
0x1E
0
Zoom by 2.
1
Zoom by 4 (if bit 0 is 0).
8
True decimation by 2. Decimate 2x will skip every other column and row, without considering the
colors of the pixels.
9
True decimation by 4. Decimate 4x will skip 3 rows/columns for every row/column read out, without
considering the colors of the pixels.
10
True decimation by 8. Decimate 8x will skip 7 rows/columns for every row/column read out, without
considering the colors of the pixels.
