摘要： An image sensor includes a pixel array with a plurality of pixels. A pixel includes a photodiode, a first transfer gate, a storage gate, and a second transfer gate. The first transfer gate is controllable to transfer charge from the photodiode to under the storage gate. The storage gate is connected to a readout circuit to allow the readout circuit to read out a voltage level of a potential at the storage gate. The second transfer gate is controllable to transfer charge from under the storage gate. A method includes controlling the first transfer gate to transfer charge from the photodiode to under the storage gate, reading out a voltage level of a potential at the storage gate using the readout circuit that is connected to the storage gate, and controlling the second transfer gate to drain charge from under the storage gate.

摘要： An A/D converter suitable for use in a system in which the signal power of noise increases with the signal power of the signal, such as an imaging system, utilizes a variable quantization system for converting analog signals into digital signals. The variable quantization is controlled so that at low signal levels the quantization is similar or identical to conventional A/D converters, while the quantization level is increased at higher signal levels. Thus, higher resolution is provided at low signal levels while lower resolution is produced at high signal levels.

摘要： The present invention provides an improved pixel readout circuit that compensates for common mode noise during a read out operation. This is accomplished by using a differential readout of the signal and reset value from the desired pixel compared with the reset value from a reference pixel. In this manner common mode noise can be offset and therefore minimized. In one embodiment of the invention, the reference pixel is the nearest neighbor pixel in the same row. In another embodiment, the reference pixel is the nearest neighboring pixel in a different row.

摘要： A pixel circuit for an image sensor uses a common reset transistor for resetting both of a photodiode node and a memory node. Respective transfer gates connect the common reset transistor to the photodiode node and to the memory node, and connect photodiode node and the memory node to each other. A source follower enabled with a row select gate provides a readout signal from the memory node. The use of the common reset transistor and the operational timing of the circuit elements improves fixed pattern noise arising from transistor feedthroughs in the pixel circuit.

摘要： A binning circuit and related method, wherein pixel signals from column circuits in a sensor circuit are sampled and interpolated. The binning circuit samples analog pixel and reset signals from different sensor circuit column lines. Once a predetermined number of column lines are sampled in the binning circuit, the sampled pixel signals are averaged together in one operation, while the reset signals are averaged together in another operation.

摘要： Wide dynamic range operation is used to write a signal in a freeze-frame pixel into the memory twice, first after short integration and then after long integration. The wide dynamic range operation allows the intra-scene dynamic range of images to be extended by combining the image taken with a short exposure time with the image taken with a long exposure time. A freeze-frame pixel is based on voltage sharing between the photodetector PD and the analog memory. Thus, with wide dynamic range operation, the resulting voltage in the memory may be a linear superposition of the two signals representing a bright and a dark image after two operations of sampling.
