Pixel circuit for global electronic shutter |
摘要 |
An image sensor formed of an array of pixels, each pixel including a photodiode coupled between a first reference voltage and a first switch, the first switch being operable to connect the photodiode to a first node; a capacitor arranged to store a charge accumulated by the photodiode, the capacitor being coupled between a second reference voltage and a second node; a second switch coupled between the first and second nodes, the second switch being operable to connect the capacitor to the first node; and read circuitry coupled for reading the voltage at the second node. |
