Abstract
An image display device includes a display section adapted to display an image, a photometric section including a variable wavelength interference filter adapted to transmit light with a predetermined wavelength from incident light and a photosensor adapted to detect light obtained by dispersion, and disposed so as to be opposed to the display section, and a control section adapted to control the display section and the photometric section, and the control section obtains a spectrum of the incident light based on light intensity of the light detected by the photosensor, and then performs a color correction of the display section based on the spectrum.
Claims8
An image display device comprising:
- a display section adapted to display an image;
- a photometric section being disposed so as to be capable of being opposed to at least one pixel of the display section,
- the photometric section having a spectroscopic element adapted to disperse light from the pixel, and a detection section adapted to detect light dispersed by the spectroscopic element;
- and
- a control section adapted to control the display section and the photometric section,
- the control section obtaining a spectrum of the light from the pixel based on light intensity of the light that is dispersed by the spectroscopic element and is detected by the detection section,
- the control section performing a color correction of the pixel based on the spectrum, and
- wherein the photometric section includes a case having a front panel, a back panel, and a side panel, the back panel including a light passage disposed at a position overlapping the spectroscopic element, an interference filter adjacent to the light passage, and a circuit board disposed on the front panel, the detection section being disposed between the interference filter and the circuit board.
