发明名称 PICTURE IMAGE PICKUP DEVICE
摘要 PURPOSE:To provide optional gradation characteristics by driving selectively a display cell in a time applied with weighting to correct uneven exposure at a position on a photosensitive sheet corresponding to each display cell to eliminate density unevenness to an picked-up picture. CONSTITUTION:The lightness level of a video signal from an image reproducing processor 1 is converted sequentially into stages of digital signals by an A/D converter 9 and written on an RAM11. A CPU13 applies a weighted correction processing correcting unevenness of exposure on a position of a photosensitive sheet corresponding to each display cell to a video signal versus drive time data group. The CPU13 reads sequentially the corrected drive time data group as a display command, gives it to an LCD controller 8 which drives selectively a liquid crystal module 7 for display control.
