PROBLEM TO BE SOLVED: To uniform luminance in each projection image when projecting images by using a plurality of projector apparatuses. SOLUTION: The plurality of projector apparatuses overlap images based on input image signals to each other by mutually shifting the images by a prescribed amount and project the overlapped images to a screen 2. Then, the luminance of an image area composed of a plurality of projection images projected to the screen 2 is observed. Then, on the basis of the observation result of the observation apparatus, the luminance values of respective pixels composing an image projected in each projector apparatus are adjusted and the adjusted luminance values are supplied to the plurality of projector apparatuses. Then the image area composed of the plurality of projection images is presented by overlapping a first projection image to a second projection image whose resolution is higher than that of the first projection image, and a prescribed pixel in the image area is overlapped by corresponding pixels of projection images from n adjacent projector apparatuses.

PROBLEM TO BE SOLVED: To miniaturize a mount base without deteriorating the optical performance of a camera built in a portable electronic device. SOLUTION: A camera 3 is built in the main body 2 of a portable electronic device 1. The camera 3 has a case 11 of nearly cylindrical shape, which is placed so that the axial center of the cylinder is directed longitudinally and freely turnably around the axis center. A mirror 12 is provided to an upper end of the case 11 to freely open/close in the vertical direction. A reflection face 12a is formed to the inside of the mirror 12. When the mirror 12 is in use, it is fixed so that the reflection face 12a is tilted downward with respect to the front side by about 45 degrees as shown in figure (B). On the other hand, when the mirror 12 is not in use, it stuffs up the inside of the case 11. Lenses 13, 14 are placed so that their optical axes are almost aligned to the axis center of the case 11. A photoelectric conversion element 15 is placed at the image forming position of the lenses 13, 14 and converts an optical signal into an electric signal.
