Patents by Inventor Narumi Matsuoka

Narumi Matsuoka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11798143
    Abstract: An image processing apparatus that records a high dynamic range (HDR) signal as a file. The apparatus acquires information indicating peak luminance corresponding to one output dynamic range, of a plurality of different output dynamic ranges, in accordance with shooting settings of the HDR signal. The apparatus then records a first value based on the acquired information to the file along with the HDR signal.

  • Patent number: 11770511
    Abstract: An image processing apparatus for generating an image to display on a display configured so that a setting for maximum display luminance can be changed, obtains an image signal and the setting, generates the image to display by executing image processing including tone conversion on the obtained image signal, and sets a tone characteristic used in tone conversion based on the setting. The tone characteristic is for allocating a signal value of the image signal to a luminance range according to the setting, and shows a relationship in which a logarithmic value of the signal value of the image signal and an absolute luminance are roughly identical in at least a portion of the luminance range, independent of the setting.

  • Patent number: 11196938
    Abstract: An image processing apparatus acquires a high dynamic range (HDR) signal generated in compliance with an HDR standard, detects a region for which a highlight alarm indication is to be provided, by applying a threshold to the HDR signal, and provides a highlight alarm indication for the detected region. The HDR standard is a standard in which luminance values are handled as absolute values, and the region is detected by applying a threshold that is based on a possible maximum value of the HDR signal.
