摘要:
Where a hybrid disc has different types of media, the light spot moves among recording layers of the different media, after loading the disc into an optical disc apparatus, there is a problem that information on a media type of each recording layer should be recorded in DI etc. of the optical disc (100). Detailed information on the hybrid disc is stored in DI, by changing a disc layer type identifier or a disc structure in DI such as BCA or PIC on the optical disc (100).

The present invention aims to provide a reproduced signal evaluation method and a write adjustment method for offering a Blu-ray disc having a large storage capacity with excellent media compatibility. An evaluation index L-SEAT is calculated through signed addition using a Euclidean distance difference calculated from at least one of target signals in which a focused edge is shifted to the right and left, and the quality of the reproduced signal is evaluated based on the evaluation index. Write condition adjustment using the index enables write adjustment not depending on SNR and achieving high adjustment accuracy.

A content reception equipment for accessing an in-home content transmission equipment from a remote place executes a first authentication process with the content transmission equipment in advance, executes the remote access information sharing process required for access from a remote place, and causes the information on the content reception equipment and the remote access information to be registered in an equipment information table of the content transmission equipment. In the case where the in-home content transmission equipment is accessed by the content reception equipment brought out of home, the content transmission equipment transmits the content to the content reception equipment only in the case where the information on the content reception equipment is registered in the device information table of the content transmission equipment and the second authentication process using the remote access information is successfully executed between the content transmission equipment and the content reception equipment.

An input device (100) includes an input unit (102) for inputting a predetermined motion image signal, a motion detector (200) for detecting a motion on the basis of the motion image signal inputted into the input unit, a video signal processor (202) for outputting a predetermined video signal, and a controller (201). The controller (201) controls the video signal processor so that, when a motion detector (200) detects a first motion, the video signal processor outputs a video signal to explain a predetermined second motion to be next detected by the motion detector after the detection of the first motion to a user.

An optical disk device for recording/reproducing information on/from a multi-layer optical disk (100) moves a light focusing point for several layers by one focus jump. The optical disk device includes a controller (120) to detect a level of a focus error signal to change an output level of a focus drive signal, and the controller changes timing to change the output level of the focus drive signal based on the number of layers for the focus jump.

Disclosed is an optical unit for an image display device, the unit including: one or a plurality of light sources; one or a plurality of optical elements that control a spread of light; a combining element that combines the beams of light emitted from the light sources; and a scanning element, wherein the light from each of the light sources generates an elliptical beam spot on a screen and the spot has a major axis substantially perpendicular to a scanning direction, the result is that the unit is simple in structure, inexpensive, compact, lightweight, and capable of providing high-resolution image quality, thus providing the display device reduced dimensionally and in weight. Such an image display device using the optical unit is also disclosed.
摘要:
When a super resolution technology for optical disks is used in a situation where optical disk management information is formed with a signal that cannot be reproduced by a reproduction method based on a conventional optical disk technology, optical disk drives 302 cannot make recording adjustments and/or reproduction adjustments. An optical disk drive 302 uses an optical disk 301 that forms a management information signal with pits not smaller in size than optical resolution and can be read by a reproduction method based on a conventional optical disk technology, and makes recording adjustments and/or reproduction adjustments in accordance with management information in a control data area (CDA), and especially, optimum recording power adjustments and/or optimum reproduction power adjustments for a super resolution region, which is a user data area (UDA). When the optical disk drive 302 records information onto or reproduces information from the optical disk 301 having the super resolution region, which is the user data area (UDA), it is possible to make proper recording adjustments or reproduction adjustments and perform a proper recording operation or reproducing operation in an optical disk's information region for user information recording or reproduction.
摘要:
A television device structured to automatically adjust the color temperature on the display screen in accordance with the viewing environment includes an external light detection unit or an optical sensor for detecting the illuminance and the tint of the ambient light, and an image quality control unit or a microcomputer for adjusting quality of the video image to be displayed on the display panel. The image quality control unit adjusts the color temperature of the video image to be displayed in accordance with the illuminance value and the tint value detected by the external light detection unit. The optical sensor includes an illuminance sensor for mainly detecting the visible light, and an infrared sensor for mainly detecting the infrared light. The illuminance value and the tint value are obtained based on the output values of those two sensors.
