S1：

Aptina‘s MT9M021/MT9M031 sensor is capable of a maximum resolution of 1280 x 960
at up to 45fps, or it may be configured to run 720p at 60fps。

Registers y_addr_start,
x_addr_start, y_addr_end, and x_addr_end are used to specify the image window. The
minimum value for x_addr_start is 0 and the maximum value for x_addr_end is 1279.
The minimum y_addr_start and maximum y_addr_end are 0 and 975, respectively.

 

S2:

row_time = （active_pixels + horizontal_blank_pixels）/ PIXCLK_frequency 

 

S3:

The MT9M021/MT9M031’s outputs can be tri-stated with the OE_BAR pin. Before the
external pin can be used to control output enable, set register R0x301A[6] = 0 to disable
the output drivers. Then set R0x301A[8] = 1 to enable the input pins (OE_BAR, TRIGGER,
and STANDBY). Driving OE_BAR low will enable the output drivers, while driving it high
will tri-state the parallel output pins. The parallel outputs can also be tri-stated by
setting R0x301A[7] = 0.
