发明名称 VIDEO CAMERA PROVIDED WITH PROJECTING MEANS
摘要 PROBLEM TO BE SOLVED: To recover deterioration in projected image due to lens distortion in a video camera which has a function to reproduce a recorded image and project it through an image pickup lens. SOLUTION: A video signal after shading correction is subjected to image display on a liquid crystal panel 3 through a reverse shading circuit 7 which is used for preliminarily correcting a video signal reproduced by a signal processing circuit 8 in accordance with the distortion by a lens 1. Light of a light source is applied to a liquid crystal image, the projected light is reflected by an optical path changing means 2 and is projected to a screen that is installed outside through the lens 1. Thus, it is possible to obtain a projected image that does not have image deterioration by shading correction of the circuit 7.
