  • Publication number: 20140246564
    Abstract: Methods, apparatus and systems may operate to copy pixel charge, compensating for image subject shift within in an imaging array during exposure time of an imaging device. Activities may include transferring charge from one or more source pixels to one or more buffer pixels within the same pixel array, and copying the charge to destination pixels within the same pixel array prior to an end of the image integration time. Charge transfer may include transfer of charge from more than one array on a single die. Additional activities may include transferring charge from one or more source pixels to one or more destination pixels multiple times prior to the end of the image integration time.

  • Publication number: 20130313409
    Abstract: An imaging device that stores charge from a photosensor under at least one storage gate. A driver used to operate the at least one storage gate, senses how much charge was transferred to the storage gate. The sensed charge is used to obtain at least one signature of the image scene. The at least one signature may then be used for processing such as e.g., motion detection, auto-exposure, and auto-white balancing.

  • Patent number: 8531550
    Abstract: Automatic exposure adjusting device considers the image on a pixel-by-pixel basis. Each pixel is characterized according to its most significant bits. After the pixels are characterized, the number of pixels in any particular group is counted. That counting is compared with thresholds which set whether the image is over exposed, under exposed, and can optionally also determine if the image is seriously over exposed or seriously under exposed. Adjustment of the exposure is carried out to bring the image to a more desired state.

  • Patent number: 8212906
    Abstract: An imaging device having pixels that store charge from a photosensor under at least one storage gate during a sampling period. A driver used to operate the at least one storage gate, estimates how much charge in the pixel exceeds a predetermined limit during a non-destructive pixel sensing operation. A specific voltage is stored on the pixel's floating diffusion region to flag how many times the pixel exceeded the limit. The final pixel signal and the stored information is readout at the end of integration period to create a sum that represents the pixel's final signal value.

  • Patent number: 7924337
    Abstract: An imager having two panels of pixels (i.e., the imager's rows of pixels are split into two panels) that are controllable by separate row decoders. The dual panel architecture allows pipelining of pixel readout and column readout operations to improve the imager's frame rate. The dual panel architecture may use a standard pixel configuration, a shared column and/or a shared row and column configuration.

  • Patent number: 7825967
    Abstract: An imager having column-wise clamp voltage drivers. Each clamp voltage driver is substantially identical to the output circuitry of the imager's pixels in that column and is designed to track the noise experienced by the readout pixels. Each clamp voltage driver generates and drives the appropriate clamp voltage to store reset and pixel signals in associated column sample and hold circuitry while suppressing the noise typically experienced during the readout process.
