摘要:
An in-vehicle navigation apparatus transmits a present position, a destination, and a version number of in-vehicle map data stored in an in-vehicle map storage portion to a map difference data distribution apparatus. The map difference data distribution apparatus calculates a route from the present position and destination received from the in-vehicle navigation apparatus, compares a version number of map data stored in a center map storage portion with the received version number of the in-vehicle map data to prepare map difference data of map elements contained in the route, and distributes the prepared map difference data to the in-vehicle navigation apparatus.
摘要:
An apparatus includes a map data storage device, a map update device, a determination device, and a data production device. The storage device stores map data. The update device reflects a first map update to a first version of the map data to produce a second version of the map data when the first map update occurs. The update device reflects a second map update to the second version of the map data to produce a third version of the map data when the second map update occurs after the first map update. The determination device determines whether the first and second map updates depend on each other. The production device produces map differential data from the first and second map updates when the determination device determines that the first and second map updates depend on each other.

When three-dimensional images are displayed on various display apparatuses, the images are displayed in a state that allows for stereoscopic vision even if the size of the display apparatus is large or even if the resolution of the display apparatus is low.The apparatus includes: a decision means for deciding based on the standard information contained in the control information whether the amount of parallax on the display screen when three-dimensional image data is displayed is greater than the amount of parallax on the optimal display apparatus for displaying the three-dimensional image data; and an image processing means for implementing an image process for changing the amount of parallax, and adjusts the amount of parallax of three-dimensional images in accordance with the ratio between the pitch between dots of the standard display apparatus for displaying three-dimensional images and the pitch between dots of an own terminal.

In map data having link information, each of the links has reference information regarding a start point node of the link, a next link in a series of links, and an upper link. Further, links are memorized in a form of link list, and the position of the link in the link list is not changed in the course of adding/deleting a link, thereby enabling a direct reference to each of the links in the link list by the position of the link. The link information organized in the above-described manner enables the ease of the update of the map data as well as the speed-up of the calculation of, for example, a navigation route.
摘要:
In an image pickup apparatus, timer 2 starts a time measuring operation when a shutter button is pressed. When a time T1 is measured by timer 2, the image from CCD 1 is output as a background image to a background image buffer 4. In addition, when a time (T1+T2) is measured by timer 2, the image from CCD 1 is output as a normal image to a region extracting portion 5 and image compressing portion 6. The background image mainly refers to an image only including a background. The normal image mainly refers to an image with an object of interest arranged in front of the background.

An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller (102) designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter (101) creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator (103) creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer (104) converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

A semiconductor device includes a semiconductor substrate. A gate electrode is formed on the semiconductor substrate via a gate insulating film. A source region and a drain region of a first conductivity type are formed on the first side and the second side of the gate electrode, respectively, in the semiconductor substrate. A punch-through stopper region of a second conductivity type is formed in the semiconductor substrate such that the second conductivity type punch-through stopper region is located between the source region and the drain region at distances from the source region and the drain region and extends in the direction perpendicular to the principal surface of the semiconductor substrate. The concentration of an impurity element of the second conductivity type in the punch-through stopper region is set to be at least five times the substrate impurity concentration between the source region and the drain region.

A video coding device capable of making coded data have a hierarchical structure, a specified area of each frame is selected. The position and the shape of the selected area are encoded, a pixel value of the selected area is encoded as slower-layer coded data, a pixel value of a whole image is encoded as first upper-layer coded data by using pixel values of already decoded images of the lower-layer and the first upper layer and a pixel value of the selected area is encoded as second upper-layer coded data by using pixel values of already decoded images of the lower-layer and the second upper layer.
