1. Row skip mode should have no effect on the integration time. Column skip mode changes
2. Default for Reg0x05 = 9. However, sensor ignores any value for Reg0x05 less than 19.
Sensor timing is shown above in terms of pixel clock and master clock cycles (please
refer to Figure 6). The recommended master clock frequency is 48 MHz. The vertical
blank and total frame time equations assume that the number of integration rows (bits
13 through 0 of Reg0x09) is less than the number of active plus blanking rows (Reg0x03 +
1 + Reg0x06 + 1). If this is not the case, the number of integration rows must be used
instead to determine the frame time, as shown in Table 5.
the effective value of Column Size (Reg0x04) as follows:
Column Skip 2 => R4eff = (int(R4 / 4) x 2) + 1
Column Skip 4 => R4eff = (int(R4 / 8) x 2) + 1
Column Skip 8 => R4eff = (int(R4 / 16) x 2) + 1
where the int() function truncates to the next lowest integer. Now use R4eff in the equa-
tion for row time instead of R4
