Abstract
An image sensing device, such as a CMOS Active Pixel Sensor device, including an array of pixels. Each pixel has a photoreceptor, a follower transistor connected to said photoreceptor, a select transistor connected to said follower transistor, and a reset transistor which controls applying a reset level to a pixel that is different than the pixel in which said reset transistor is physically located.
Claims11
An image sensor, comprising:
- a plurality of pixels, each having a photoreceptor therein, a follower transistor connected to said photoreceptor, a select transistor connected to said follower transistor, and a reset transistor which controls applying a reset level to a pixel that is different than the pixel in which said reset transistor is physically located.
An image sensor, comprising:
- a first pixel comprising a first photoreceptor, a first follower transistor connected to said first photoreceptor, a first select transistor connected to said first follower transistor, and a first reset transistor;
- a second pixel comprising a second photoreceptor, a second follower transistor connected to said second photoreceptor, a second select transistor connected to said second follower transistor, and a second reset transistor;
- a third pixel comprising a third photoreceptor, a third follower transistor connected to said third photoreceptor, a third select transistor connected to said third follower transistor, and a third reset transistor;
- a first line connected to a gate of said first select transistor and a gate of said second reset transistor;
- a second line connected to said first follower transistor and said second reset transistor;
- and
- a third line connected to said second follower transistor and said third reset transistor.
