Title: Holography transmitting system
Inventor: KOMIYA KAZUMI
IPC: G03H1/22
Filed: 1988-06-20
Abstract: PURPOSE:To reduce the quantity of required transmitting information by separately reproducing and displaying holograms of a still and moving objects on a reproducing side. CONSTITUTION:On a reproducing side, the hologram of a still or almost still object to which a relatively small quantity of transmitting information is required is reproduced and displayed in the 1st reproducing section 15a composed of the 1st recording medium having a high resolution. The hologram of a relatively quickly moving object to which a larger information transmitting quantity is required is reproduced and displayed in the 2nd reproducing section 15b composed of the 2nd recording medium having a lower resolution than the 1st recording medium. When the holograms of a still and moving objects are separately reproduced and displayed in such way, the entire quantity of the transmitting information can be reduced as compared with the case where both holograms of the still and moving objects are rewritten altogether by using a single recording medium with a high resolution at a uniform high speed.

Title: Video signal recording/reproducing device
Inventor: EGUCHI SUSUMU
IPC: G11B5/02
Filed: 1988-06-17
Abstract: PURPOSE:To produce a desired control signal within a cylinder and to control the inside of the cylinder by detecting the local magnetic field generated by a magnetic field generating device via a magnetic head fixed to a rotary drum at a point close to this drum. CONSTITUTION:When an AC power supply is applied to a magnetic field generating device 1, a magnetic field is generated at a point extremely close to the device 1. Thus an induced current flows to a magnetic head 3a or 3b when this head passes through a point close to the device 1. This current signal is amplified by a preamplifier and a control signal is produced by a monostable multivibrator which stabilized at 3T/4. Then the head 3a (or 3b) is kept under a recording state for a period during which a cylinder is turned by 3/4 right after the head 3a passes through a point close to the device 1. The head 3a (3b) is reset to a reproduction state after the 3/4-turn of the cylinder. As a result, an R/P control signal can be transmitted within the cylinder with no contact with a rotary drum.

Abstract: PROBLEM TO BE SOLVED: To provide an image area separate function capable of parallel processing with a small circuit scale by configuring a quantization means with a quantization table and a quantization value selector means. SOLUTION: An edge is detected by using a filter and based on a prescribed threshold level, pattern matching is conducted to discriminate a consecutive edge and a quantization value of a quantization table is decreased when a consecutive edge is in existence for each prescribed block.
