IPC: H04N1/401
Filed: 1994-11-30
Abstract: PURPOSE: To obtain a satisfactory picture quality by making the number of lines for read of a white reference plate for transmission original larger than that for read of a white reference plate for reflection original. CONSTITUTION: A number N1 or tunes set for read or a reflection original and a number N2 of lines set for read of a transmission original always have relations N1<N2. At this time, a line number change means is operated to make the number of lines of white reference data for transmission original read larger than that for reflection original read.

Filed: 1990-10-31
Abstract: PURPOSE:To prevent sound shock noise by suppressing a sound output when detection of horizontal synchronization of a high definition television signal is disabled. CONSTITUTION:A MUSE signal inputted from an external BS tuner is inputted from an input terminal A, converted into a digital signal by an A/D converter 1 and converted into an NTSC signal at a video signal processing circuit 2 and outputted to an external monitor through a terminal B.

IPC: G11B19/28
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To optimally set rotational speed in a disk device which makes rotation control by the CAV (constant angular velocity) system. SOLUTION: A MD 1 on which data is recorded by the CLV(constant linear velocity) system is divided into plural regions in the diametrical direction and for each of these regions a rotational number enlarged toward the inner peripheral side is set. Divided regions, address information corresponding to these regions and the rotational numbers corresponding to the regions are set in advance as table information. The outermost shell record position is determined based on the end address information of sector zero of the U-TOC(User TOC) read from the MD 1. With reference to the table information, which region the record position of the outermost shell belongs to is judged and the corresponding rotational number is determined. The rotation of a motor 2 is controlled by the CAV system based on this number of rotation.  Since data is adaptively set in accordance with the recorded region, high-speed disk drive is enabled. And in intermittent readout, further saving of power consumption is made possible.
