Abstract: In a case when a camera is disposed under a display panel, a bounded part between a camera area and a surrounding area may have a brightness difference due to a difference in pixel disposition density. The present disclosure allows minimizing such a boundary effect by compensating for greyscale values of pixels in the bounded part.

Abstract: An object of the present invention is to provide the image display system, the image display device, the image display method and the computer program that can enhance usability when changing a luminance setting value. The image processing unit is configured to set a gradation characteristic of the image data to be displayed on the image display unit to a first gradation characteristic and simultaneously switch a luminance setting value from a first luminance setting value to a second luminance setting value when the image display system accepts a request to change the luminance setting value of the image display unit from the first luminance setting value to the second luminance setting value, and then switch the gradation characteristic of the image data to be displayed on the image display unit to a second gradation characteristic.

Abstract: An illumination device of the present disclosure includes: a first light source unit that emits first light of a first wavelength band; a first spatial light modulator where the first light from the first light source unit enters; a second light source unit that emits second light of a second wavelength band; an integrator optical system including a first fly-eye lens where the second light from the second light source unit enters and generating illumination light for an illumination target on a basis of the first light having been modulated by the first spatial light modulator and the second light from the second light source unit; and a multiplexing optical system that multiplexes the second light having entered the first fly-eye lens and the first light having been modulated by the first spatial light modulator, in an optical path between the first fly-eye lens and the illumination target.

Abstract: An electronic device comprises a plurality of display devices, a designation unit that designates one of a plurality of predetermined color balances for which adjustment values of the plurality of display devices are set in advance, and an adjustment unit that adjusts color balances of the plurality of display devices. The adjustment unit performs a first adjustment for adjusting the color balances of the plurality of display devices using adjustment values of the color balance designated by the designation unit, and a second adjustment for adjusting the color balances of the plurality of display devices that have undergone the first adjustment, wherein resolution of the second adjustment is higher than resolution of the first adjustment.
