1-6. Line Rate and Frame Rate Control (Virtual Frame)
and depth are controlled by effective WOI and blank depths. The effective WOI is scaled by the sub-sampling
factors from WOI set by register values. For CDS and ADC function, the virtual column width must be larger than
(adcres+1)*256/(2^mcdiv)+200, where adcres is the ADC resolution control register value. The horizontal and
vertical blanking time (hblank, vblank) should be over 60 and 4, respectively. 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
types of integration mode are implemented. In the rolling shutter mode (sfcim=0), 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 :
18
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). There are two
The line rate and the frame rate can be changeable by varying the size of virtual frame. The virtual frame’s width
1 frame time = { wrd / (subsr+1) + vblank } * (1 line time)
1 line time = { wcw / (subsc+1) + hblank } * (DCLK period)
Integration Time = { TBD }
where cintr = 0 to {TBD}, cintc = 0 to {TBD}.
Integration Time = sint * (1 line time)
