IMAGE SENSOR AND COMPUTING SYSTEM HAVING THE SAME

摘要

An image sensor includes a light-electron conversion unit, a signal generation unit, and a selection unit. The light-electron conversion unit generates photo-charges from incident light. The signal generation unit accumulates photo-charges from the converter in a storage node during a detection period, and then generates a first analog signal and a second analog signal during an output period. The analog signals are generated based on an amount of photo-charges accumulated in the storage node. The selection unit generates an image signal based on one of the first analog signal and the second analog signal.

主权项

1. An image sensor, comprising:
a light-electron conversion unit configured to generate photo-charges from incident light; a signal generation unit configured to accumulate the photo-charges from the light-electron converter in a storage node during a detection period, and to generate a first analog signal and a second analog signal based on a first transmission control signal and a second transmission control signal, respectively, during an output period; anda selection unit configured to generate an image signal based on one of the first analog signal or the second analog signal, wherein the first analog signal and the second analog signal are generated based on an amount of the photo-charges accumulated in the storage node and wherein the second transmission control signal is applied after the first transmission control signal.
