TIME CODE IMAGE SENSOR |
摘要 |
An image sensor including: a first control circuit; a plurality of pixels, each including a photodetector, a comparator of the level of an output signal of the photodetector with a reference value, and a second control circuit connected to the first control circuit, the second circuit being capable of sending a signal of address reading request to the first circuit when the pixel turns on, of receiving an address reading acknowledgement signal transmitted by the first circuit, and of deactivating the pixel on reception of the reading acknowledgement signal; and at least one third control circuit capable, when a pixel receives a reading acknowledgement signal, of blocking the transmission of address reading request signals in at least one adjacent pixel. |

1. An image sensor comprising:
a first control circuit; a plurality of pixels, each comprising a photodetector, a comparator of the level of an output signal of the photodetector with a reference value, and a second control circuit connected to the first control circuit, the second circuit being capable of sending a signal of address reading request to the first circuit when the pixel turns on, that is, when the level of the output signal of its photodetector reaches the reference value, of receiving an address reading acknowledgement signal transmitted by the first circuit, and of deactivating the pixel on reception of the reading acknowledgement signal; and at least one third control circuit capable, when a pixel receives a reading acknowledgement signal, of blocking the transmission of signals of address reading request in at least one adjacent pixel. |
