20080239126 | CMOS solid-state image pickup apparatus - Basically, en electronic shutter function of a CMOS solid-state image pickup apparatus is implemented by a rolling shutter of which exposure timing sequentially shifts between pixel rows. The exposure period for one pixel row is from a time point when readout of the pixel row is started to a time point when next readout of the pixel row is started. Thus, in order to achieve exposure similar to that of a global shutter with the same exposure period applied to all of the pixel rows, there is set a blank period where no pixel signal is read out from any one of the pixel rows, and an LED is illuminated over a predetermined portion within the blank period. In this way, the CMOS solid-state image pickup apparatus having a rolling shutter function can achieve similar exposure to a global shutter. | 10-02-2008 |
20090316031 | CMOS solid state imaging device - Each pixel of a pixel matrix portion includes a photo diode, a floating diffusion, a transfer transistor for transferring a storage charge of the photo diode to the floating diffusion in response to a transfer pulse, a reset transistor for resetting the floating diffusion in response to a reset pulse, and a reading circuit for reading a voltage of the floating diffusion to a column signal line in response to a row selection pulse. A timing generator repeats a counting of subframes, and switches a frame consisting of the subframes in designated number. A vertical scanning circuit controls whether or not the reset pulse, the transfer pulse, and the row selection pulse should be fed to respective rows of the pixel matrix portion every subframe, and controls timings of the reset pulse and the transfer pulse in each subframe. | 12-24-2009 |
