    Abstract: An imaging apparatus includes an imaging unit, a signal processing unit, and a pixel interpolation processing unit. The apparatus calculates a correlation degree for pairs in two orthogonal directions for an image signal obtained by the imaging unit including a single-chip image sensor having a four-color filter, such as a WRGB color filter, using pixel data in an area around a target pixel, using the correlation degree as a determination criterion in the interpolation. When a color component pixel with an identical color of a color component pixel subjected to pixel interpolation is not located in the direction having the high correlation, the pixel interpolation apparatus changes ratio in a direction orthogonal to the direction having the high correlation by using a pixel value resulting from color space conversion in the direction orthogonal to the direction having the high correlation, and performs pixel interpolation based on the change ratio.

  • Patent number: 9197791
    Abstract: A display device is disclosed. The display device includes a first horizontal line having a first sequence of colored pixels, and a second horizontal line having a second sequence of colored pixels. The display device also includes a signal controller for detecting a first input video signal and a second input video signal for pixels respectively disposed on a left outermost vertical line and a right outermost vertical line of the display from an input video signal. The signal controller also corrects the first input video signal and the second input video signal so that they have grayscales that are less than a threshold value. The image quality characteristic is improved by removing the color shift phenomenon of the right and left outermost vertical lines in the display device.

  • Publication number: 20150146054
    Abstract: An image sensor may be provided with an array of imaging pixels. A color filter array may be formed over photosensitive elements in the pixel array. The color filter array may include color filter elements of different sizes. The color filter array may include color filter elements of at least three different sizes. The color filter array may include color filter elements of only two different sizes. Each color filter element by be square, octagonal, or rectangular. Microlenses of different sizes may also be formed on top of the color filter elements of different sizes. Forming color filter elements with different sizes may help skew the quantum efficiency for light at particular wavelengths of interest so that smaller pixel sizes can be used without suffering from diffraction limits.

  • Publication number: 20150124129
    Abstract: According to the present invention, since a color image for a moving image including that for live view display includes image data on pixel lines including first and second phase difference pixels, phase difference AF can be accurately performed during the moving image taking. A color image for the moving image includes not only the image data on the pixel lines including the first and second phase difference pixels, but also image data on pixel lines that do not include the first and second phase difference pixels and only include normal pixels. Accordingly, the image quality of the color image for the moving image is improved, an image interpolation process can be accurately performed, and reduction in image quality of a taken image (still image and moving image) through the phase difference pixels can be prevented or alleviated.

    Abstract: One aspect of the present invention thinning-reads pixel signals from the multiple pixels according to a thinning pattern from an image pickup element, or extracts pixel signals from the multiple pixels according to the thinning pattern from a color image that is read from the image pickup element and corresponds to the color filter array, and acquires a thinned color image. Then, moving image data is generated on the basis of the thinned color image. Adoption of the thinned color image as a target image to be subjected to moving image processing can facilitate reduction in processing time per frame, and prevent the frame rate from decreasing. Furthermore, thinning-reading pixels from the image pickup element can facilitate reduction in time of reading an image from the image pickup element.
