  • Patent number: 8860864
    Abstract: An object of the present invention is to reduce display delay time in a live view display. An image capturing device has an image data generation unit that generates image data per line of a display section based on an output of an image capturing sensor in which a start and an end of charge storing are controlled per line, a display control unit that causes the display section to display generated image data sequentially per line, and a control unit that ends charge storing after a first amount of time passes since charge storing of an image capturing target line is started, and starts displaying image data of a display target line corresponding to the image capturing target line after a second amount of time passes since charge storing of an image capturing target line is ended. The second amount of time is time required for starting displaying image data in a display target line after charge storing of an image capturing target line is ended.

  • Patent number: 8836832
    Abstract: An image pickup system includes an image pickup element with an image pickup region in which a plurality of pixels are arranged in a matrix, and a controller configured to control reading of signals from the pixels. The controller divides a first frame period in which a first image is read from the image pickup element into a plurality of divided frame periods, including first and second divided frame periods. When the number of pixels included in the first image is larger than the number of pixels included in a second image, a second frame period required for reading all signals from the pixels included in the second image is inserted between the first and second divided frame periods. A refresh cycle of the second image is shorter than a refresh cycle of the first image.

  • Patent number: 8830366
    Abstract: In an apparatus, operation is switchable between first and second modes. In the first mode, a photoelectric conversion part and a charge storage part are released from a reset state for all pixels included in an image acquisition area to start a period, and, when a predetermined time has elapsed, the photoelectric conversion part and an overflow drain region of each pixel are turned onto end the period, and finally the charge stored in the charge storage part is transferred to the amplifier part. In the second mode, after a mechanical shutter is opened to start a period, the mechanical shutter is closed to end the period, and stored charge is transferred to the amplifier part.

  • Patent number: 8830367
    Abstract: An image sensor of a camera system captures an image over an image capture interval of time, and waits a blanking interval of time before capturing an additional image. The captured image is provided to a frame controller, and is buffered until an image signal processor accesses the captured image. The image signal processor processes the accessed image over an image processing interval of time, producing a processed image. The image processing interval of time is selected to be greater than the image capture interval of time, but less than the sum of the image capture interval of time and the blanking interval of time. By reducing the image capture interval of time but maintaining an image processing interval of time, rolling shutter artifacts are beneficially reduced without increasing the processing resources or power required by the image signal processor to process the image.

  • Patent number: 8823846
    Abstract: Providing for pausing data readout from an optical sensor array is described herein. By way of example, an interruption period can be introduced into a readout cycle of the optical sensor array to suspend readout of data. During the interruption period, other operations related to the optical sensor array can be performed, including operations that are typically detrimental to image quality. Moreover, these operations can be performed while mitigating or avoiding negative impact on the image quality. Thus, greater flexibility is provided for global shutter operations, for instance, potentially improving frame rates and fine control of image exposure, while preserving image quality.

The pixel circuitry includes a transfer-storage transistor, a charge-storage area, an output transistor, and a floating diffusion region. The transfer-storage transistor is coupled between the photosensitive region and the charge-storage area. The output transistor has a channel coupled between the charge-storage area and the floating diffusion region and has a gate tied to a fixed voltage potential. The transfer-storage transistor causes the image charge to transfer from the photosensitive region to the charge-storage area and to transfer from the charge-storage area to the floating diffusion region.

  • Publication number: 20140226047
    Abstract: A method for operating a global shutter image sensor includes performing both a global shutter (image capture) operation and a rolling shutter (readout) operation. During the global shutter operation, image information (charges) are captured by photodiodes in every pixel, and then simultaneously transferred to charge coupled gate (CCG) devices provided in each pixel. The rolling shutter operation includes performing multiple correlated double sampling (CDS) readout phases utilizing readout circuits that are shared by groups of pixels (e.g., four pixels share each readout circuit) having CCG devices connected in a chain. After resetting a floating diffusion in the readout circuit, a first captured charge is transferred to floating diffusion for readout, and the remaining charges are shifted along the CCG chain. The remaining CCG devices are then sequentially read out by repeating the read-and-shift operation. The readout operation is then repeated for each row of pixel groups.

Each pixel includes a photodiode, a transfer gate and a charge coupled gate (CCG) device. The CCG devices are coupled in series with the floating diffusion of the shared readout circuit. Control circuitry controls the image sensor such that all of the pixels simultaneously capture image information (charges) and then transfer the captured charges to the CCG devices during a global shutter operation. The control circuit then controls the CCG devices to act as a shift register that transfers the captured charges to the floating diffusion during sequential correlated double sampling readout phases. The readout circuit includes a shared reset transistor, a source-follower and row select transistor, and each pixel group is controlled by eight or fewer control signals.
