Abstract: A pixel cell and readout circuit includes an anti-eclipse voltage clamp circuit at both the top and bottom of each column line of an array of the pixel cells. The anti-eclipse voltage clamp circuits form a row with each column in the array coupled to an anti-eclipse voltage clamp circuit. The combination of two rows of anti-eclipse voltage clamp circuits helps settle the clamp voltage more rapidly and to compensate for the increased length of the anti-eclipse voltage circuit row as well as the column line resistance due to narrow metal lines and increased numbers of pixels as well as the requirement to operate a sensor at a higher frame rate. More significantly this circuit construction can minimize vertical shading in the resulting image.

Abstract: An image sensor has a pixel cell array comprising clusters of pixel cell blocks each block having four pixel cells under the same microlens and filter wherein during readout electrical signals from two pixels positioned along a first diagonal are binned followed by binning the signals from two pixels positioned along the remaining second reverse diagonal in order to reduce spatial color artifacts associated with orthogonal binning schemes and minimize gaps or irregular spacing between optical centers within an image read out from the array of pixel cells.

Abstract: An image sensor has global shutter imaging pixel cells, each including an anti-blooming transistor gate for modifying electric charge within a photodiode and for setting the photodiode to a selected potential. The sensor also has a row decoder circuit providing readout signals to each row of the imaging cells during both a readout interval and during a calibration interval for each row and providing to the anti-blooming transistor drain a selectable potential supply voltage. A mode select switch within the row decoder circuit applies either a standard drain supply voltage or an adjustable low voltage to the anti-blooming transistor drain. A programmable function logic circuit determines the timing of operation of the mode select switch to provide knee-point calibration to minimize photo conversion variations that lead to fixed pattern noise.

The row decoder may employ one of several of its features to provide a self-knee point calibration following an image signal readout in order to minimize photo conversion variations that lead to fixed pattern noise and to enhance dynamic range.
