摘要： A display device according to the present invention includes a display unit that displays an image based on an input frame, a light emitting unit including a plurality of light emitting regions whose light emission is separately controllable, and a display controller that controls the light emission of each of the light emitting regions using luminance determined for each of the light emitting regions using the input frame. When the display unit displays a first subframe in which high-frequency components of the input frame are emphasized and a second subframe in which the high-frequency components of the input frame are suppressed by switching therebetween, the display controller applies the luminance determined using the input frame to each of the plurality of light emitting regions during a period for which the first subframe is displayed and a period for which the second subframe is displayed to control the light emission.

摘要： An image processing apparatus includes a setting unit and a conversion unit. The setting unit sets a gradation threshold. The conversion unit converts a gradation value greater than the gradation threshold in an input image into a predetermined gradation value, converts a gradation value equal to or less than the gradation threshold in the input image into a gradation value equal to or less than the predetermined gradation value, and generates an output image. In a case where the input image is an image processed in such a manner as to enhance a predetermined area, the setting unit sets the gradation threshold such that a surrounding area of the predetermined area of the input image becomes equal to or less than the gradation threshold.

摘要： Provided is a display device that illuminates a printed material taking into consideration the characteristics of the printed material. The display device obtains an image for illuminating the printed material, and information pertaining to the optical characteristics, such as light reflectance or transmission, of the printed material. Then, on the basis of metadata pertaining to a luminance or color of the obtained image and the obtained information, the display device controls a light source illuminating the printed material. Through this, the display device enhances the dynamic range or the color gamut of the printed material.
