IMAGE PROCESSING DEVICE CONTROL METHOD AND IMAGE PROCESSING DEVICE

摘要

It is possible to provide an image display device and an image display method capable of performing multi-hierarchical expression. For this, the device includes a control unit (6) for data-distributing monochromatic image data to RGB according to LUT so as to generate display image data, a liquid crystal panel (2) capable of displaying the image according to the display image data, and measurement means (5) for measuring the color stimulus value of the image displayed on the liquid crystal panel (2). The control unit (6) has an LUT generation unit (13) which uses the characteristic of the liquid crystal panel (2) so as to estimate luminance and chromaticity of a plurality of candidate colors having RGB values corresponding to internal signal values which have been increased or decreased within a predetermined range, selects one of the candidate colors according to the estimation result, and corrects the LUT by using the RGB values of the selected color as the RGB values of the internal signal value.
