摘要： An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. A timing generator outputs a column address sequence that is received by a column decoder that is electrically connected to each output circuit. The timing generator suspends the output of the column address sequence during a sample operation and resumes the output of the column address sequence at the end of the sample operation.

摘要： An image sensor for capturing a color image is disclosed having a two-dimensional array having first and second groups of pixels wherein pixels from the first group of pixels have narrower spectral photoresponses than pixels from the second group of pixels and wherein the first group of pixels has individual pixels that have spectral photoresponses that correspond to a set of at least two colors. Further, the placement of the first and second groups of pixels defines a pattern that has a minimal repeating unit including at least twelve pixels. The minimal repeating unit has a plurality of cells wherein each cell has at least two pixels representing a specific color selected from the first group of pixels and a plurality of pixels selected from the second group of pixels arranged to permit the reproduction of a captured color image under different lighting conditions.

摘要： Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.

摘要： A method for reading out an image signal includes providing at least two photosensitive regions and providing at least two transfer gates respectively associated with each photosensitive region. The method also includes providing a common charge-to-voltage conversion region electrically connected to the transfer gates and providing a reset mechanism that resets the common charge-to-voltage conversion region. After transferring charge from at least one of the photo-sensitive regions, all the transfer gates are disabled at a first time. The method further includes enabling at least one transfer gate at a subsequent second time and transferring charge from at least one of the photosensitive regions at a subsequent third time while the at least one transfer gate from the second time remains enabled.

摘要： An image sensor includes a two-dimensional array of pixels having multiple column outputs and an output circuit connected to each column output. Each output circuit is configured to operate concurrent sample and read operations. An analog front end (AFE) circuit processes pixel data output from the output circuits and an AFE clock controller transmits an AFE clocking signal to the AFE circuit to effect processing of the pixel data. A timing generator outputs a column address sequence that is received by a column decoder. During one or more sample operations the timing generator suspends the column address sequence and subsequently during the one or more sample operations the AFE clock controller suspends the AFE clocking signal. The AFE clocking signal and the column address sequence resume at the end of the one or more sample operations.
