1/7 INCH CIF CMOS IMAGE SENSOR
1-6. Line Rate and Frame Rate Control (Virtual Frame)
and depth are controlled by effective WOI and blank depthes. The effective WOI is scaled by the subsampling
factors from WOI set by register values. For CDS and ADC function, the virtual column width must be larger than
256/(2^mcdiv)+180. The resulting frame time and line time which are inverse of frame rate and line rate are
represented by following equations:
1-7. Continuous Frame Capture Mode(CFCM) Integration Time Control (Electronic Shutter Control)
shutter control register (shutc) is set to “1”. In shutter operation, the integration time is determined by the Row
Step Integration Time Control Register(cintr) and Column Step Integration Time Control Register(cintc). The
resulting integration time is expressed as;
1-8. Single Frame Capture Mode(SFCM) Integration Time Control
mode is implemented. The integration time is controlled by SFCM Integration Time Register (sint). The light
integration period for each rows progresses with reading rows. The integration time is expressed as :
The line rate and the frame rate can be changeable by varying the size of virtual frame. The virtual frame’s width
In CFCM operation, the integration time is controlled by shutter operation. The shutter operation is done when
To capture a still image, SFCM can be set by Single Frame Capture Enable Register(sfcen). Rolling shutter
1 frame time = { wrd / (subsr+1) + vblank } * (1 line time)
1 line time = { wcw / (subsc+1) + hblank } * (DCLK period)
Integration Time = (cintr - 1) * (1 line time) + (cintc +110) * (DCLK period)
where cintr = 1 to { wrd / (subsr+1) + vblank }, cintc = 0 to { wcw / (subsc+1) + hblank –180 }.
Integration Time = sint * (1 line time)
