Abstract

PURPOSE:To read an image easily and accurately by measuring only the quantity of light on a gray scale, and thus photographing an image so that a hard copy which has the best desired degree of blackening is obtained. CONSTITUTION:An input video signal is converted by a video controller 4 into a video signal, and a display device 5 displays an image on a CRT5B and also display the brightness level of the screen of the 5B on a gray scale display part 5A by a gray scale. A sensor 8 detects the quantity of light on the gray scale, and a detection signal obtained by measuring only the quantity of light on the display part 5A is supplied to an integrator 9. The integrator 9 integrates the detection signal corresponding to a set integral time and the result is stored in a memory 11. Then, a shutter release signal is sent to a camera 15 in response to the output of a photographic signal to start photographing the image on the 5B. The photographic signal is supplied to a timer 12 as well and a phogography end signal is outputted to a controller 14 a certain time later, thereby supplying a shutter closure signal to the camera 15.
