An oscillator circuit includes a clock oscillator which outputs a main clock signal having an oscillating frequency switched between a high frequency and a low frequency in response to a frequency selection signal, and a frequency divider circuit which outputs a sub-clock signal having a divided frequency equivalent to a frequency division ratio of the oscillating frequency of the main clock signal, the frequency division ratio being switched in response to the frequency selection signal. The divided frequency of the sub-clock signal is predetermined for each of the high frequency and the low frequency to which the oscillating frequency is switched in response to the frequency selection signal.

A method and apparatus for coding an image includes calculation of motion vectors of vertices of a patch in an image being encoded and transmitting information of horizontal and vertical components of the motion vectors of the vertices and information specifying that values of the horizontal and vertical components of a motion vector for each pixel in the patch are integral multiples of 1/d of a distance between adjacent pixels, where d is an integer not less than 2.

Adopted is a decoder, in which on condition that a prediction block shown by vector information extracted from a data stream, and a decode-target block have an overlap where respective pixels overlay each other, pixel information of an already-decoded portion at a distance of an integer multiple of a vector provided by the vector information from the overlap is made a prediction signal instead of the overlap, and the prediction signal is added to difference image data taken from the data stream to generate reproduction image data. The decoder is adopted for an intra-frame decoder, a local decoder of an encoder, and the like. According to a fundamental rule concerning a repetitive pattern of an image, a pixel at a distance of an integer multiple is a like pixel, and therefore the process of decoding can be performed efficiently.

A method of extracting a keyword in synchronism with a “scene” or “corner” in a TV program that changes in units of second in synchronism with the elapse of time of first content, and an information presentation apparatus to search and display a predetermined form of content, such as a web page, are provided. The information presentation apparatus comprises: an AV content output unit to output AV content (e.g., TV programs and movies); and a web page output unit to output, together with the AV content from the AV content output unit, a web page that corresponds to a keyword related to a scene included in the content being output from the AV content output unit without the user having to take trouble to choose a keyword, the web page output unit being adapted to, when the scene in the content changes, automatically update the web page to one corresponding to the changed scene.

A high-frequency module attached with a shield case. Barrier 36 of the shield case has wall 37 provided by being bent from ceiling section 32; wall 38 that is opposed to wall 37 and that is provided by being bent from ceiling section 32; and linkage section 39 for linking the tip end of wall 38 to the tip end of wall 37. The shield case further has: a crossing section at which wall 37 crosses ceiling section 32 and side plate 33; notches 43 respectively provided at the crossing sections at which wall 38, ceiling section 32 and side plate 33 cross one another; and division section 44 for segmentalizing side plate 33 from notches 43 in downward direction. The boundary between circuit block 4 and circuit block 5 is provided at a position corresponding to barrier 36. Connection section 34 is connected to the ground of circuit block 4 or circuit block 5. As a result, a module having a superior shielding performance can be provided through which a signal from a circuit provided on the printed circuit board can be prevented from leaking.

It is desirable to distribute a most recently inputted image of merchandise in a shop without showing customers visiting a shop, or to distribute an image showing how crowded a shop is without infringing on the privacy of visitors to the ship. This is achieved by separating areas showing moving objects and areas showing no moving objects of an image and synthesizing an image showing stationary objects only by replacing the moving object area with the corresponding area of an earlier inputted image showing stationary objects only, or by processing the moving object area of an image, for example, by applying a mosaic to such an area, and synthesizing the synthesized image showing stationary objects only. The image in which the moving object area has been processed enables the distribution of an image showing how crowded a shop is without infringing on the privacy of visitors.

A vehicular visual assistance system includes: a retro-reflective surface formed on an inside face of a pillar that is in a position obstructing the view of a vehicle driver seated on a driver's seat within a vehicle compartment; a camera mounted on the vehicle outside the vehicle compartment for taking an image outward from the pillar in a direction that is substantially the same as the line of vision of the vehicle driver on the driver's seat; and a projector for projecting in real time the image taken by the camera toward the retro-reflective surface of the pillar. The projector is fixedly disposed within the vehicle compartment at a position close to the eyes of the vehicle driver on the driver's seat. Thus, it is possible to eliminate a blind spot due to the pillar, thereby enhancing safety of driving.
