  • Patent number: 8054361
    Abstract: A method and associated architecture for dividing column readout circuitry in an active pixel sensor in a manner which reduces the parasitic capacitance on the readout line. In a preferred implementation, column readout circuits are grouped in blocks and provided with block signaling. Accordingly, only column output circuits in a selected block significantly impart a parasitic capacitance effect on shared column readout lines. Block signaling allows increasing pixel readout rate while maintaining a constant frame rate for utility in large format high-speed imaging applications.

  • Patent number: 8023012
    Abstract: An image capture device provided with a first memory unit, which memorizes position information of non-continuous defective pixels of a solid-state image capture component, and a second memory unit with a higher access rate than the first memory unit, which memorizes position information of continuous defective pixels. When a continuous photography mode or a video photography mode is set, defective pixel correction processing is carried out on image data corresponding to each of defective pixels according to the defective pixel position information stored at the second memory unit. Alternatively, when a still photography mode is set, image data corresponding to all defective pixels is corrected, based on both the defective pixel position information stored at the first memory unit and the defective pixel position information stored at the second memory unit. As a result, it is possible to correct defective pixels with high efficiency in accordance with conditions of photography.

  • Patent number: 7995137
    Abstract: An exposure compensation method automatically generates an accurate exposure value to clearly show the profiles of objects in front of a black background or a white background. First, initial edge energy is derived from luminance values for pixels in a digital image having an initial exposure value. Maximum edge energy is obtained by varying an exposure compensation value for the digital image, and an optimal exposure compensation value according to the maximum edge energy is also obtained. If a difference between the maximum edge energy and initial edge energy is larger than a threshold value, a current exposure value is set to the initial exposure value compensated by the optimal exposure compensation value. Otherwise, the initial exposure value is directly designated as a current exposure value.
