    摘要: A display apparatus capable of illuminating a light modulation device with a light from a light emitting body to display an image on a display plane comprises a plurality of light emitting bodies (R, G, B) different from one another in emitted light color, a light receiving device configured to detect the light from the light emitting bodies and to output an amount of light received, and a color balance adjustment control section configured to adjust and control a color balance in the display plane in accordance with the amount of light received by the light receiving device. The color balance adjustment control section is configured to be capable of identifying the emitted light color of the light emitting body relating to the amount of light received.

    摘要: An image processing device includes: an image pickup unit, for forming an image of a target with an optical system, then taking the image using an image pickup device, and obtaining image information including the target; a target-point detecting unit, for detecting a target point where the target exists within a field as position information expressed by information unrelated to the position where the image pickup unit exists; and a relevant information generating unit, for obtaining relevant information representing the correlation between the position information detected by the target-point detecting unit and the direction where the image pickup unit takes an image of the target and/or camera coordinates on the basis of the view angle (i.e., for performing calibration). Thus, the position of the target existing within the three-dimensional field space within an image pickup region where an image of the target is taken by the image pickup unit, can be calculated.

    摘要: An illumination apparatus which applies light from light emitting members to a region to be illuminated. The apparatus includes an emitted light quantity control unit which controls emitted light quantities of the members, and a light transmissibility changing unit which controls transmissibility of each light path which transmits output light of the light emitting member to the region. The controls of the emitted light quantity control unit and the light transmissibility changing unit are performed in such a manner that an illuminative light quantity in the region during intermittent lighting of a predetermined number of light emitting members which are some of the light emitting members at a driving current value larger than a rated current in a predetermined period is larger than an illuminative light quantity in the region during constant lighting of the predetermined number of light emitting members at a rated driving current in the predetermined period.
