Image Sensor Timing and Readout
Frame Rate and Windowing
Frame Rate
The frame rate depends on the input clock, the frame overhead time (FOT), and the row overhead time (ROT). The frame period is
calculated as follows:
1 kernel = 24 Pixels = 2 Timeslots = 2 Granularity clock cycles
Table 10. Frame Rate Parameters
Note For more information on FPS calculation, refer the Cypress application note AN57864.
In global shutter mode, the whole pixel array is integrated simultaneously including the dummy line for FPN correction.
Windowing
Windowing is easily achieved by SPI. The starting point of the x
and y address and the window size can be uploaded. The
minimum step size in the x-direction is 24 pixels (choose only
multiples of 24 as start or stop addresses). The minimum step
size in the y-direction is one line (every line can be addressed)
in normal mode, and two lines in sub sampling mode.
