Title: Video signal processing unit
Inventor: HIKICHI YASUSHI
IPC: G11B20/06
Filed: 1988-05-24
Abstract: PURPOSE:To reproduce a clear luminance signal by generating a pseudo-signal from the output of a circuit, which decides the level of a clip part in the luminance signal, adding the pseudo-signal to a luminance reproducing signal, correcting the signal of the clip part and passing this signal through a de- emphasis circuit. CONSTITUTION:When the luminance reproducing signal is inputted to a level deciding circuit 6 and a delay circuit 7 and a part, for which white peak clip is executed, is inputted, a deciding output signal S is outputted. The signal S is inputted to a linear phase-shaped filter circuit 8 of a pseudo-signal generating circuit, which equips plural 1 clock delay circuits 8a, plural coefficient devices 8b and an adder 10, and a step-shaped output signal is generated only in the time of the clip. This signal is delayed only by the number of the circuits 8a and goes to be a level signal which is determined by coefficient values K1-Kn of the coefficient devices 8b. The luminance reproducing signal through the delay circuit 7 and the signal to be made in the filter circuit are synthesized and the clear luminance signal can be reproduced.

Title: Function generator
Inventor: AKAGI YOSHIYUKI
IPC: G06G7/26
Filed: 1977-10-19
Abstract: PURPOSE:To minimize the size of the hardware as well as to avoid the distortion of the output waveform by constituting the circuit of the time function generator used to the communication equipment and the like without including the multiplier. CONSTITUTION:Adder 12 functions to add the constant given from constant memory 11 to the 1-clock preceding output of shift registr 13. Decoder 14 decodes the output of register 13, and detects to which level among a0-a5, for instance, the output waveform has arrived to alter the addresses read out from memory 11 according to each level and then to vary the constant to be applied to adder 12. The digital word is produced at output terminal 15 and then converted to another waveform through D-A converter. The action timing is regulatd by a fixed clock for each of above mentioned component elements 11-14. Thus, no multiplier is used for the circuit, so the size of the hardware can be minimized. Furthermore, the distortion of the output waveform caused by the accumulation of the noise mixing in when gathering the multiplication results can be prevented.

Abstract: PURPOSE: To enhance the contrast of boundaries of an image, by using the lens of chromatic aberration to focus the permeating light and the reflection light of a recording medium having metallic luster to a photoelectric conversion element.  
     CONSTITUTION: The light emitted from visible light source 10 is incident onto the reverse face of laser direct recording film 13 moving in the direction vertical to the paper surface to generate a negative image dependent upon the visible light. Meanwhile, the light emitted from infrared light source 14 is reflected by half- mirror 17 and illuminates the surface of LDF13. This infrared light is reflected by a metallic thin film layer to form a positive image. These both images are synthesized through projection lens 18 on the photodetection face of photoelectric conversion element 19 and are subjected to photoelectric conversion. A lens of chromatic aberration is used as this lens 18, and the focus is adjusted by the visible light. Consequently, the negative image is in focus, and the positive image is out of focus, and the contrast around dots is emphasized by synthesizing them.
