摘要： PURPOSE:To obtain a constant color image regardless of the kind and the thickness, etc.,of a sheet which is used as a mask negative by using a means for detecting the light transmission of the mask negative and a means for controlling exposure. CONSTITUTION:The title recorder is provided with light transmissivity detection means 38a and 38b for detecting the light transmission of the mask negatives 22R, 22G, 22B(22) and an exposure control means 39 for controlling at least either intensity or total exposing time according to the light transmissivity of the mask negative 22 detected by the light transmissivity detection means 38a and 38b. The exposure controlled by the exposure control means 39 is executed to a photosensitive pressure sensitive recording medium 24 by an exposing device. Thus, the constant color image can be obtained regardless of the kind and the thickness, etc., of the sheet which is used as the mask negative 22.

摘要： PURPOSE:To keep white balance in a photosensitive part constant by correcting the spectral exposure of light which reaches the photosensitive part to be constant according to the detection output from a light detection means. CONSTITUTION:The light detection unit (photosensor) 24 is set in an optical path between a spectral transmittive filter 23 and the photosensitive part 30. The detection output from the light detection means 24 are processed to be compared so that the control of comparison is performed by executing feedback to a CRT circuit. By setting the light detection unit 24, the luminance of the spectral light emission of the light which reaches the photosensitive part 30 can be measured. By controlling the CRT, the spectral exposure of the photosensitive part 30 can be always kept constant. Thus, the white balance in the photosensitive body 30 can be kept constant even if the distribution of the spectral light emission of the CRT is changed according to a temperature, etc.

摘要： PURPOSE:To obtain a still picture faithful to a signal source, also to accept a high-speed video signal and further to reduce the size and cost of the image recording device by imposing speed conversion on a binary-coded signal and projecting binary images corresponding to respective levels on a monitor television successively and recording them on a film one over another. CONSTITUTION:The voltage value outputted by a comparison voltage generator 14 is the lowest voltage value V1 at a controller 10, and a voltage comparator 12 converts a video signal of one red image screen into a binary signal on the basis of the voltage value V1. A video signal corresponding to odd-numbered scanning lines in the binary-coded video signal is decomposed into picture elements with a sample clock signal from a clock generator 20, and the picture elements are stored in line memories 18a and 18b alternately and successively and also read out of the line memories 18a and 18b alternately at a speed half the write speed. The signal read out of a storage means 16 is scanned on the monitor television 24 to obtain a monochromatic binary image. At this time, a red color filter 26 is selected, so the red binary image is recorded on the film 30.

摘要： PROBLEM TO BE SOLVED: To provide a time division color separating device capable of automatically changing over color ratios of a color wheel to the optimum color ratio. SOLUTION: In a time division color separating device performing the color separation of the white light from a light source in time-division manner, this device has the color wheel 2 provided with two color rings 2a, 2b whose color ratios are different, an input signal discriminating circuit 10 discriminating whether either of an input signal of input signals of R, G, B or a video input signal is input, a slide bar 3 for moving the color wheel 2 in a direction the wheel 2 crosses the optical path of the white light, and a color wheel movement control circuit 7 for controlling the movement of the color wheel 2 by the slide bar 3. When the input signal is the input signal of R, G, or B, the color wheel movement control circuit 7 inserts the color ring 2a in the optical path and when the input signal is the video input signal, the circuit 7 inserts the color ring 2b in the optical path.
