Title: Optical disk device
Inventor: ARAI AKIHIRO
IPC: G11B7/095
Filed: 1992-01-21
Abstract: PURPOSE:To accurately control by detecting with two photodetectors, envelope- detecting the output signal of each photodetector and tracking-controlling by regarding the difference of each detected signal as a tracking control signal. CONSTITUTION:The output of a quadripartite photodetector 1 is added by a specified formula and amplified, and signals TA1, TA2 are outputted. The signal TA1 is envelope-detected by a detector 30 through an HPF 27 and becomes the signal TB1 and the signal TA2 is processed by the HPF 28 and the detector 31 and becomes the signal TB2 similarly. The signal TE2 obtained by subtracting the signal TB2 from the signal TB1 is outputted by a subtractor 25. The result of a comparator 23 is investigated by a system controller 16 and a selector 24 is switched so that the signal TE2 is outputted when the amplitude of the signal TE2 is larger than a prescribed value and the TE1 is outputted when smaller, and a tracking control part 13 is tracking-controlled. Thus, accurate tracking-control is performed regardless of the kind of a track.

Filed: 1983-01-20
Abstract: PURPOSE:To register a device connected to a system from a main controller at an optional time, by providing a register key on an operation part for the purpose of recognizing and registering a device connected to an information line. CONSTITUTION:When an oil FF hot blast heater is connected as an air conditioner while the system is operated, it is necessary to register this connection to a main controller 1.

Title: Image recording/reproducing device
Inventor: MATSUGI MASAKAZU
IPC: G06T7/00
Filed: 1994-01-28
Abstract: PURPOSE:To shorten the operation time by preventing the extraction of parallax at a place near a shielding contour and by extracting the parallax for each block and in consideration of the human stereoscopic sense characteristic. CONSTITUTION:The images photographed by two cameras 1L and 1R provided on a stage 2 are recorded as the image data on the memories 3L and 3R respectively. When these image data are supplied to an image processing part 4 from both memories 3L and 3R, the parallax discontinuous contours of the image data are extracted. Then the image data are divided into plural blocks of each prescribed size so as to avoid the crossing to the parallax discontinuous contours. The parallax of each image is extracted for each divided block. Based on the extracted parallax, a both-eye visual area is discriminated from a single- eye visual area. The parallax of the both-eye visual area is converted into the parallax that is accordant with the placement of a reproduction optical system. Thus the stereoscopic images are generated and displayed at an image display part 5.
