摘要： The image signal superimposing portion generates an image signal for displaying images in a superimposed manner by using at least three layers, i.e., first to third layers. A main moving image is displayed in the first layer. A still image generated by an OSD generating portion is displayed in the second layer. A sub moving image having a display size smaller than that of the main moving image is displayed accessorily in the third layer. The first layer is displayed below the second layer, and the second layer is displayed below the third layer. The image signal superimposing portion superimposes these three layers of images so as to generate a single hierarchical image signal. When a hiding instruction receiving portion receives a hiding instruction, the hiding portion generates an opaque color image in the second layer by using the OSD generating portion so that the main moving image displayed on a layer below an OSD layer becomes invisible.

摘要： In a method for processing at least 2 kinds of silver halide color photographic light-sensitive materials comprising the steps of development, bleach-fixing, water washing and/or stabilization, the method comprises processing, in a common bleach-fixing bath and a common water washing or stabilization bath directly subsequent thereto, one silver halide color photographic light sensitive material having, applied to a substrate, a silver halide emulsion layer which contains, on average, not less than 3 mole % of silver iodide and another silver halide color photographic light sensitive material having applied to a substrate a silver halide emulsion layer which is substantially free of silver iodide, the water washing or stabilization bath containing at least one nonionic surfactant. The amount of replenisher for the bleach-fixing bath and the water washing or stabilizing bath is reduced to not more than 400 ml/m.sup.2 for color paper or not more than 800 m1/m.sup.2 for color negative film. The method makes it possible to simultaneously process different color light-sensitive materials such as color negative films and color paper and to thereby reduce the space required for installing an automatic developing machine.
