  • Patent number: 7990424
    Abstract: A device is provided for taking high resolution still pictures while recording video without pausing video recording. Plural channels are provided for reaching pixel values from a CMOS sensor, and the output of each channel is input to a corresponding A/D conversion circuit. The channels are configured so that the pixels that are added together are read simultaneously. The data added by the pixel value adder is used as the video data for video recording. When a still picture is captured during video recording, the pixel data is stored in memory with capacity to store one frame, and is sequentially output from the image sensor as the still picture data.

  • Publication number: 20100238339
    Abstract: When a method or apparatus of assuring simultaneous exposure, such as a mechanical shutter, is not provided with a MOS imaging sensor, moving subjects are distorted with a MOS image sensor when capturing a still image of a fast-moving subject because imaging and reading are not simultaneous across the MOS sensor. Changing the MOS sensor exposure sequence and reading sequence, and interpolating the read data, change and correct the read sequence line by line when imaging a high resolution moving image, and thus improve distortion in moving subjects.

  • Publication number: 20090225227
    Abstract: In the calculation of a motion vector, a motion vector of different block with a small correlation value is considered in addition to an estimated motion vector of a target block. This different block is a block at a position where a movement similar to the target block is predicted. As a result, a motion vector with a small correlation value for the different block is adopted even if a correlation value for an estimated motion vector of the target block is large. This enables the detection of a highly reliable motion vector.
