  • Patent number: 11196951
    Abstract: An imaging device acquires first dark image data in a state where an image sensor has been light shielded, acquires second dark image data in a state where the image sensor has been light shielded, based on completion of exposure, corrects fixed pattern noise of a reference combined image data based on at least one of the first dark image data and the second dark image data, and stores the reference combined image data that has been subjected to correction.
    Type: Grant

  • Patent number: 11050930
    Abstract: An imaging apparatus includes: an imager including an imaging sensor configured to acquire an optical image; and a processor configured to: perform pixel displacement to displace a positional relationship between a subject and the imager in a unit of a pixel pitch or less; detect an amount and a direction of a shake; perform shake correction to correct the positional relationship between the subject and the imager based on a detection result; perform first imaging for a first predetermined number of times for each position of the pixel displacement to generate a first group of images; combine the images of the first group to generate a first high-resolution image; perform second imaging for a second predetermined number of times for each position of the pixel displacement to generate a second group of images; and combine the images of the second group to generate a second high-resolution image.

  • Patent number: 10459190
    Abstract: An imaging apparatus includes: an imaging unit; an image clipping unit configured to clip a predetermined area from each of images; an analyzing unit configured to analyze the sequentially clipped predetermined areas and generate an analysis result indicating an identified subject; an autofocus (AF) target determination unit configured to determine an AF target in the images based on the analysis result; an AF mode determination unit configured to select and determine an optimal AF mode based on the analysis result and a determination result; a touch panel; an input detection unit; and an imaging control unit configured to repeat control of moving a position of the predetermined area, causing the analyzing unit to analyze the predetermined area of a latest image, causing the AF target determination unit to determine the AF target, and causing the AF mode determination unit to select and determine the optimal AF mode.

  • Patent number: 9854158
    Abstract: A display control unit 110 that displays an image adjustment window in which saturation of a specified hue is set by a two-dimensional coordinate in which a hue is made to correspond to an angular direction and levels of saturation of respective hues are made to correspond to distances in a radial direction and a CPU 140 that specifies the hue through first manipulation input, and sets saturation of the specified hue through second manipulation input are included, and the display control unit displays a polygon representing a relative relationship between levels of saturation of respective hues set by the CPU in the image adjustment window.
