Abstract: An image display device including a display unit and a computing device that is operable to function as units including a clipping unit which clips an image of one portion from a fisheye image captured by using a fisheye lens as a clipping target area, a correcting unit which corrects distortion of the image clipped by the clipping unit, a specifying unit which specifies a vertical direction of a corrected image acquired by the correcting unit, based on orientation information when the fisheye image is captured, and a display control unit which controls the corrected image to be displayed on the display unit based on the vertical direction specified by the specifying unit.

Abstract: In the present invention, in a state where a photographing parameter of an imaging section (for example, the focal length of a zoom lens) has been set within the range between a first value (for example, a wide angle end of 18 mm) and a second value (for example, a telephoto end of 140 mm), and a reference value (for example, 28 mm) for the photographing parameter has been set within the range between the first value and the second value, a control section changes the set parameter to the reference value.

Abstract: A projection display apparatus includes a light source unit for generating light for image formation, an electro-optical display device for displaying an optical image by utilizing the light emitted from the light source unit, and an enlarging/projection lens. The light source unit, the display device, and the projection lens are accommodated in a housing with vent openings. The housing also includes a fan for cooling the interior of the housing with cool air and a cooler for maintaining a display panel within a predetermined temperature range. The light source unit includes a lamp and a reflector and is designed not to cause image deformation and formation of a shadow of a discharge portion. In order to display a television image on the display device, all television image display circuit units excluding an antenna are accommodated in the housing. The enlarging/projection lens can control a magnification and a focal point of the image projected on the screen.
