  • Publication number: 20240333863
    Abstract: A color matching control apparatus capable of accurately matching colors of images from different cameras. The color matching control apparatus obtains first and second images including a color chart area from different cameras, extracts first pixel values of the color chart area in the first image, extract second pixel values of the color chart area in the second image, calculate a dynamic range of the color chart area in the first image based on the first pixel values, sets a first singular point in an area excluding the color chart area in the first image based on the dynamic range, sets a second singular point in the second image based on the first singular point, and generates a parameter for color matching between images picked up by the different cameras based on the first and second pixel values and the pixel values of the first and second singular points.

  • Publication number: 20230317031
    Abstract: A display control apparatus that easily discriminates residual color difference between a plurality of image pickup apparatuses at a site where the image pickup apparatuses are used. The display control apparatus including a memory device that stores a set of instructions, and at least one processor that executes the set of instructions to obtain an adjustment image from an adjustment image pickup apparatus that performs predetermined color matching with a reference image pickup apparatus, generate residual color difference information showing color difference from a reference image picked up by the reference image pickup apparatus that remains in the adjustment image, and generate display information from the residual color difference information.

  • Publication number: 20210097941
    Abstract: A control apparatus controls a display apparatus including a light-emitting module and a display panel configured to display an image based on image data on a display surface by modulating light emitted from the light-emitting module. The control apparatus includes at least one memory containing instructions and at least one processor which, by executing the instructions, functions as a control unit configured to control the display apparatus so that a patch image for calibration of the display apparatus is displayed on the display surface. In a case where an emission brightness of the light-emitting module is controlled in accordance with the image data, the control unit controls the display apparatus so that a patch image that is smaller than the display surface is displayed on the display surface.

  • Patent number: 8446533
    Abstract: In an AV system in which a television apparatus and a recorder are individually connected to an AV amplifier through an HDMI, in the case where sound is output from the AV amplifier, if insertion of headphones into the television apparatus is detected, control information to switch the destination of the audio data is transmitted from the television apparatus to the AV amplifier. The AV amplifier switches the destination of the audio data that is input from the recorder from a speaker output section to the television apparatus in accordance with the control information. Thus, even if the headphones are inserted into the television apparatus while the AV amplifier is outputting sound reproduced by the recorder, the sound can be output from the headphones.
