Abstract: An image detection unit extracts image feature values from images of each camera. An image conversion unit computes a blend rate according to the image feature values and composites an image of a superposition area wherein a plurality of camera images overlap. An assessment is made of a correspondence of the image feature values of each image in the superposition area, and a determination is made that a solid object is present if the correlation is weak. Furthermore, a determination is made that the solid object is present in the superposition area if the image feature values in each image have locationally overlapping portions. In such a circumstance, the image is composited with the blend rate of the image with a greater image feature value set large.

Abstract: In a projection-type video display device that displays an image by projecting the image onto a projection object starting from a desk surface, a display screen on which a position and a gesture operation of a user are reflected is displayed in a predetermined area. An illumination and a camera are disposed in the projection-type video display device installed on the desk surface, a gesture using user's fingers is detected, and, for example, a menu screen and an operation guide are displayed according to the gesture. The shadows of the fingers are photographed by the camera, and a gesture is detected. According to the gesture, the display screen is moved, rotated, divided, or enlarged/reduced, or a menu screen is displayed. The display direction is determined in consideration of the direction of sides of the desk.
