Patent Images

1. An image processing apparatus comprising:

  • an input interface configured to input image data;

    at least one processor configured to;

    obtain an output pixel value by adjusting at least one selected from luminance, resolution, and precision regarding a portion of the image data,adjust a tone curve denoting a correlation between input pixel values and output pixel values, and based on the adjusted tone curve, to obtain, with regard to at least one of pixels comprised in the image data, an output pixel value corresponding to an input pixel value, andselect a partial range having high luminance from among an entire range of input pixel values of the adjusted tone curve, thereby changing the output pixel value corresponding to the input pixel value in the selected range; and

    an output interface configured to output image data comprising the obtained output pixel value to buffer storing the image data, andwherein the selected partial range having high luminance comprises input pixel values equal to or greater than a predetermined reference value.
