REGISTER
Pixel Integration Control
These registers (along with the Window S ize and Blanking registers) control the integration time for the pixels.

Number of rows of integration, default = 0x01FC (508).
Reset delay, default = 0x0000 (0). This is the number of master clocks x 4 that the timing and cont rol
logic wait s before asserting t he reset for a given row.
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 shif ted relative to the data out by setting bit 8-11 of
Reg0x07 appropriately. Maximum value for 0x0A = 0x0015.
Set ting bit 0 to “1” of Reg0x0B will cause t he sensor to abandon the readout of the current frame
and restart from t he first row. This register automatically resets itself to 0x0000 after t he frame
restart. The first frame after t his event is considered to be a "bad frame" (see description f or
Reg0x20, bit 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 by 2.
Zoom by 4 (if bit 0 is 0).
True decimat ion by 2. Decimate 2x will skip every ot her column and row, without considering t he
colors of the pixels.
True decimat ion by 4. Decimate 4x will skip 3 rows/columns for every row/column read out, wit hout
considering the colors of the pixels.
True decimat ion by 8. Decimate 8x will skip 7 rows/columns for every row/column read out, wit hout
considering the colors of the pixels.
