摘要： There is described a medical image recording system for recording an image on a reflex-type recording medium based on image information, and a medical image recording system for recording with ink-jet the medical image information obtained through an input device, such as a medical photographing device. The system includes an image-processing section to apply a dynamic-range compression processing to original image signals representing the medical image and inputted therein, in order to generate output image signals, and an image-forming section to form a compressed medical image on the reflex-type recording medium, based on the output image signals generated by the image-processing section. The dynamic-range compression processing is to compress a dynamic-range of density variation to be expressed on the reflex-type recording medium.

摘要： According to a spurious pulse generator of this invention, integrating circuits are provided at a plurality of stages for carrying out integrating operations about time and outputting a spurious pulse, the integrating circuits being constructed to input a voltage value for controlling a crest value which is a peak swing of the spurious pulse to an amplifier forming an integrating circuit at a most upstream stage when a switching element is ON, and to input a constant voltage value when the switching element is OFF. As a result, the voltage value before ON-state and after ON-state of the switching element does not change but remains a constant voltage value, thereby obtaining a desired spurious pulse.
