PROBLEM TO BE SOLVED: To make a brightness of each part of an image to be constant in the case of displaying when three dimensional partial image and two dimension partial image coexist, by controlling the brightness of each part of the image by a light quantity adjustment means according to the number of visual points. SOLUTION: A visual points detection part 8 detects, from the inputted or synthesized image data, whether a partial image is two dimensional (the number of visual points 1) or three dimensional, and how many number of visual points it has in the case of a three dimensional image. The visual points detection part 8 outputs detected each information on the number of visual points to a first image processing part 9 in parallel with each image data. Also, each information on the number of visual points is outputted to the light quantity adjustment circuit 6. The first image processing part 9 properly arranges two or more image data, and forms image information for one screen, and sends it to LCD1 driving circuit 5, and displays a synthesized image on a display for LCD1. Optical amount adjustment circuit 6 controls an emitted light quantity of each division area of a back light 3, based on window area designation information and information on the number of visual points. |
