Patent ID: 8164657

Claim:
A complementary metal-oxide-semiconductor imaging system-on-chip sensor including a system thereon that maintains a substantially uniform frame rate, comprising: a transfer signal inhibition component configured to transmit, for a selected frame of a pixel array sampled during a calibration mode, a first command to block triggering of transfer signals to gates of transfer transistors of pixels in the pixel array while sampling signals in the pixel array for the selected frame to generate a calibration frame, and to transmit a second command to unblock triggering of the transfer signal for a first subsequent frame relative to the selected frame; a frame duplication component configured to replicate a data frame obtained prior to transmission of the first command and replace the calibration frame in an outputted sequence of frames with the data frame; and a gain control component configured to apply a negative digital gain to digital signals associated with the first subsequent frame, and to apply a positive digital gain to digital signals associated with a second subsequent frame following the first subsequent frame, wherein the negative digital gain and the positive digital gain are substantially equal in magnitude.
