| 摘要 |
<p>The invention concerns an image sensor formed of an array of pixels (300), each pixel including a photodiode (302) coupled between a first reference voltage and a first switch, the first switch being operable to connect the photodiode to a first node (308); a capacitor (322) arranged to store a charge accumulated by the photodiode, the capacitor being coupled between a second reference voltage and a second node (321); a second switch (320) coupled between the first and second nodes, the second switch being operable to connect the capacitor to the first node; and read circuitry (314, 318) coupled for reading the voltage at the second node.</p> |
