We have developed a HDTV (high-definition TV) museum system according to the guidelines proposed by the Association for the Promotion of Hi-Vision museums. Newly developed fundamental technology in the system includes (1) a total system controller, (2) an operation panel with combined functional control and (3) time management software, With these techniques we have realized a basic museum system, which also offers additional functions such as automatic system control and easy input and editing of the operating schedule. These functions allow us to simplify system management and control, thereby resulting in a system with high added value.
We have developed a super high definition image filling system. This system can store and process 3840 × 2560 pixels images with JPEG compression. Operator can do image I/O operation, processing and retieval on HDTV monitor assisted with use friendly GUI. This system can be applied to medical image data base and so on.
The MPEG1 algorithm is standardized by ISO-IEC JTC1/SC29/WG11. An LSI technology for compression with MPEG1 is developed. The picture compression technology seems likely to find use in a wide variety of application. Under these circumstances, we developed th Digital Vision KARAOKE system and KARAOKE-CD standard with MPEG1 coding technology. In this paper, MPEG1-SYSTEM standard and KARAOKE-CD standard are introduced mainly. An authoring system is also described roughly.
X-ray systems are widely used for blood vessel imaging because of their high imaging resolution. They have, however, two drawbacks: they expose patients to radiation, and a contrast medium needs to be injected into the blood system. Although MRI systems are completely safe, the images they produce lack the resolution of X-ray images since rapid signal fall-off makes clear vessel images difficult to acquire. Our new imaging method shortens the time taken to capture the NMR signal. This improves resolution to a level where blood vessels only 0.1 mm wide can be imaged using an experimental system (magnetic field strength 4.7T , bore size 30 cm), the highest resolution level ever achieved by a MRI system.
Recently, for a Video Cassette Recorder and a Camcorder, miniaturization and reduction of their weight and components have been required. For those requirement, we have developed a Y・C processing LSI which includes Luminance (Y) and Chrominanc (C) signal processings on a chip. The LSI consists of more than 10,000 elements, using our new precess (L6000), which can reduce its power dissipation half as much as than of conventional one. In the LSI, a 11 order LPF for Y-Signals can be switched four frequency responses according to imput signals. In addition to that, BPF for C-Signals can be also switched four and frequency responses respectively. Using these circuits, the LSI can be used for various input signals.
