Ultra low voltage CMOS image sensor architecture |
摘要 |
An optical sensor has at least one pixel that generates an output voltage that changes at a rate dependent on the light intensity incident on the pixel. The time for the pixel output voltage to change from a first predefined level to a second predefined level is measured, so as to produce an output indicative of the incident light intensity.
