Digital pixel sensor and operating method thereof |
摘要 |
A digital pixel sensor, comprising a first switch coupled between a first voltage and a first node, turned on or off by a rest signal to provide a first voltage to the first node when turned on; a light sensing unit coupled to the first node generating a transformation current responsive to the intensity of an incident light source and thereby discharging the first node, and a decision device coupled with the first node and a reference signal to output an intensity reference signal corresponding to the intensity of the incident light source when the voltage at the first node is discharged to a level below that of the reference signal
