Table 13 shows the maximum frame rates that can be achieved at various common
image sizes with a data rate limit of 640 Mb/s (CCP2). The frame rates are shown with
subsampling enabled (x_odd_inc = 3, y_odd_inc = 3). The frame rates assume a pixel rate
of 64 Mp/s (vt_pix_clk = 64 MHz) and the minimum line blanking of 574 pixels/
minimum frame blanking of 85 lines.
The integration (exposure) time of the MT9M019 is controlled by the
fine_integration_time and coarse_integration_time registers.
The limits for the fine integration time are defined by:
< =
The limits for the coarse integration time are defined by:
If coarse_integration_time>(frame_length_lines-coarse_integration_time_max_margin)
then the frame rate will be reduced.
The actual integration time is given by:
With default settings and a vt_pix_clk of 64 MHz, the maximum integration time that
can be achieved without reducing the frame rate is given by:
