Image processing device and method

Abstract: The present disclosure pertains to an image-processing device and method that make it possible to suppress block noise. A βLUT_input calculator and a clip processor determine βLUT_input, which is a value inputted to an existing-β generator and an expanded-β generator. When the value of βLUT_input qp from the clip processor is 51 or less, the existing-β generator determines β using a LUT conforming to the HVEC standard, and supplies same to a filter process determination unit. When the value of βLUT_input qp from the clip processor is larger than 51, the expanded-β generator determines the expanded β and supplies same to the filter process determination part. This disclosure, for example, can be applied to an image processing device.

Method and apparatus for providing program oriented information in a multiple station broadcast system

Abstract: An innovative but easy to use on-line program list is provided to provide the user of a multiple channel television broadcast system a wealth of programming information in a simple format that is easy to understand. The guide enables the user to easily select a particular program to watch or to watch in the future. Unlike prior art television guides, the present invention presents a program list that is oriented according to the program instead of the channel. In particular, the program list provides program information and the times the program is broadcasted the displayed timeframe. This is particularly useful for viewing in one simple and easy-to-read format the start times of a pay-per-view program, which may, for example, be broadcasted every 1/2 hour over a variety of channels.

The Continuator: Musical Interaction with Style

Abstract: We propose a system, the Continuator, that bridges the gap between two classes of traditionally incompatible musical systems: (1) interactive musical systems, limited in their ability to generate stylistically consistent material, and (2) music imitation systems, which are fundamentally not interactive Our purpose is to allow musicians to extend their technical ability with stylistically consistent, automatically learnt material This goal requires the ability for the system to build operational representations of musical styles in a real time context Our approach is based on a Markov model of musical styles augmented to account for musical issues such as management of rhythm, beat, harmony, and imprecision The resulting system is able to learn and generate music in any style, either in standalone mode, as continuations of musician’s input, or as interactive improvisation back up Lastly, the very design of the system makes possible new modes of musical collaborative playing We describe the architectu

Optical device for bar-code reading, method for manufacturing an optical device, and light projection/receiving package

Abstract: An optical device for bar-code reading capable of improving the degree of freedom in design of component lenses so as to allow free positional adjustment of the lenses while ensuring downsizing and weight reduction of the device, and a method for manufacturing are disclosed. An optical device for bar-code reading comprises a light emitting element; a light projection lens for focusing light from the light emitting element so as to irradiate a bar code; a light receiving lens for focusing reflected light from the bar code and having formed therein a penetrating hole which penetrates a plane of incidence of light and a plane of outgoing of light, in which the light projection lens is inserted; and a light receiving element for receiving the light focused by the light receiving lens so as to perform photo-electric conversion.

Optical device, and virtual image display device

Abstract: A virtual image display device with an optical waveguide to guide, by internal total reflection, parallel pencil groups meeting a condition of internal total reflection, a first reflection volume hologram grating to diffract and reflect the parallel pencil groups incident upon the optical waveguide from outside and traveling in different directions as they are so as to meet the condition of internal total reflection inside the optical waveguide and a second reflection volume hologram grating to project the parallel pencil groups guided by internal total reflection inside the optical waveguide as they are from the optical waveguide by diffraction and reflection thereof so as to depart from the condition of internal total reflection inside the optical waveguide.
