  • Patent number: 11637964
    Abstract: An image processing apparatus for performing processing that rounds down C bits from an A-bit image, and that causes a B=(A?C) bit image resulting from the rounding down processing to be displayed comprises a time dithering unit configured to express a pixel value that is an intermediate value of one step in the (A?C) bits in the A-bit image by selectively outputting in each frame across N frames a value where the intermediate value was rounded down and a value where the intermediate value was rounded up, and to artificially express the A-bit image with a dither pattern where the N frames is a minimum unit, wherein the time dithering unit sets the value of N so that M/N is 25 or more.

  • Patent number: 9386237
    Abstract: An image processing device performs image processing on an image being captured to display the image on a display unit having a resolution lower than a resolution of the image. The image processing device includes an extraction section that extracts an edge component from the image, an edge enhancing section that enhances the edge component by performing low-pass filter processing on the edge component after performing full-wave rectification processing on the edge component, a combining section that combines the enhanced edge component with the image to generate a composite image, and a resolution conversion section that performs resolution conversion of the composite image to match a resolution of the composite image with the resolution of the display unit.

  • Patent number: 8625019
    Abstract: An image sensing apparatus includes a display control unit which controls an image display unit to display an image sensed by an image input unit. The image sensing apparatus also includes a signal strength detection unit which detects, from a sensed image, a luminance area formed from pixels satisfying a predetermined luminance condition, and a special area detection unit which detects, from a sensed image, an object area having a predetermined feature. The display control unit controls the image display unit to display an assist image representing the luminance area, so as to be superimposed on a sensed image. The display control unit changes the assist image display method between a case in which the luminance area and object area overlap each other and a case in which they do not overlap each other.

  • Publication number: 20110234614
    Abstract: An image processing apparatus is configured to designate an area of an input image signal, enlarge a waveform of a signal included in a designated area among generated waveforms, set a display color of the enlarged waveform to a different color, and output the waveform having the set display color by imposing over the generated waveform.
