At first, we made the value function to value color fidelity. Next we optimized the factors of color improvement matrix of CCD video camera founded on this value function with the S/N values of Quality Engineering. Finely we accomplished the color high-fidelity with a little varience.
Video camera recorders have function of digital title, since we can easily insert hand-made titles in video images. To realize large miniaturization of size of the chip, and decrease in power, we placed the memory (S-RAM), which was out of the chip, in the titler. And we utilized the technology of data compression and interpolation for memorizing data using half as much memory as in the past. In addition, we have developed the digital titler that has the function of shadow title and frame indication.
Recently, camcorders for consumer use have become more and more compact. efficient, and functional. Here the rapid progress of technology in the optical system is playing a very important role. This report gives a brief survey of the trend of the optical system for camcorders, mainly from the view point of its compactness. We also clarify the problems which confront us now.
We have developed new Auto White Balance system. At the Signal Processing Method. While Balance is influenced by the color of the image. So we applied the Fuzzy Logic to Auto White Balance. Microcomputer make a conjecture on the light, it can control adaptively.
This paper describes an improvement of motion vector detector of automatic electronic image stabilizer (EIS) for camera-recorders and VCRs utilizing only video signal processing. Developed technologies are new detection system to discriminate moving objects, improvement of detection probability, and suppression of motion vectors due to noise by increasing motion vector detection area.
We have developed a fully digitalized camera signal processor fabricated with 1.4um CMOS technology. This chip contains 120k transistors, 2H line memory and 2 D/A converters. Which operate with a 3.6V power supply. 10-bit signal processing and adaptive filtering scheme have improved image quality. This chip can use both in the NTSC system, and in the PAL system.
