<p>PURPOSE:To attain the high-speed recording of a color picture by applying voltages repeating blue, green and red colors to respective picture elements of an optical shutter array to execute image recording. CONSTITUTION:A slit plate 3 having a slit 4 and the optical shutter array 6 obtained by arraying many picture elements 7B, 7R, 7G alternately are successively arranged between a white light source 1 and a photosensitive material 2. A slit beam passed through the slit plate 3 is made incident upon the array 6, optically modulated and emitted so as to be supplied to the exposure of the photosensitive body 2. The array 6 is functioned as a color filter consisting of repeated blue, red and green filter parts 7B, 7R, 7G on which respective picture elements practically transmit only the light with a specified wavelength in the order of blue, red and green by driving voltages corresponding to respective colors controlled from a control part 9 driven by receiving an image signal 8. Consequently, respective color filter functions can be obtained with a short waiting time and image recording can be speeded up.</p> |
