A navigation apparatus is provided that is highly convenient for a user to view a map screen and a menu window. A display controllerdetermines a view mode of each of a map screen and a menu window, based on information about a travel condition of a moving object from a route search unitand an own-vehicle location identification unit, when the menu window is displayed according to information entered from an input unit. A display map generatorgenerates a map screen according to information about the view mode from the display controller. A display menu generatorgenerates a menu window according to information about the view mode from the display controller. A display unitdisplays the map screen from the display map generatorand the menu window from the menu generator

Navigation apparatus

A navigation system capable of enabling a user to use navigation functions such as route guidance without setting a destination. It includes an information recording unit for storing a driving history, a destination estimating unit for estimating a destination from the driving history stored in the information recording unit, a route computing unit for calculating a route to the destination estimated by the destination estimating unit, and an information display unit for causing the route calculated by the route computing unit to be displayed.

Navigation system for estimating and displaying candidate destinations

A navigation device includes a map databasethat holds map data; a location and direction measurement unitthat measures the current location and direction of a vehicle; a route calculation unitthat, based on map data read from the map databasecalculates a route from the current location measured by the location and direction measurement unit to a destination; a camerathat captures video images ahead of the vehicle; a video image acquisition unitthat acquires the video images ahead of the vehicle captured by the camera; a road width acquisition unitthat, based on road width data included in the map data read from the map database, calculates the width of a road segment that enters last into an intersection to which the vehicle is to be guided from among road segments that make up the route calculated by the route calculation unit; a video image composition processing unitthat limits the length of a portion that indicates a turning direction of a route guide arrow to the road width calculated by the road width acquisition unit, and that composes the arrow onto the video images acquired by the video image acquisition unit in a superimposing manner; and a display unitthat displays the video image composed by the video image composition processing unit.

Navigation device

The image processing device comprises a first function block section formed of functional blocks which require a supply of power so as to maintain the image processing device in an operating state when the power supply is on, and a second function block section formed of functional blocks which need not be supplied with the power so as to maintain the image processing device in an operating state even when the power supply is on. The supply of power to the second function block section can be stopped when desired, while continuing the supply of power to the first function block section, thereby saving the power.

Image processing device, method for saving power consumption of the image processing device, and a computer product

A programmable image processor capable of realizing a plurality of image formation operations is comprised of an SIMD type data operation processing section, RAMs, memory controllers, and memory switches. The memory controller and the memory switches selectively connect the plurality of RAMs to the data operation processing section thereby changing the memory capacity allotted to each image formation operation among a plurality of image formation operations.

Method and apparatus for image processing, and a computer product

The image processing apparatus comprises an image data control section and a system controller. The image data control section is connected to any one or more of a sensor board unit, an image-memory access control section, an image processor, a video data control section, and a facsimile control unit. The system controller switches, when the image data to be transmitted to the image data control section conflicts with one another, a transmission mode of the image data in conflict with one another. Further, the image-memory access control section and the image processor share jobs of performing image processing on the image data.

Method and apparatus for image processing method, and a computer product

Short-distance radio communication equipment having a Bluetooth communication feature can maintain a stable reception status by automatically adjusting the reception status of an antenna when the reception status thereof deteriorates.

Radio communication apparatus

An image processor has a controller unit connected to at least one of functional units such as an image reading unit, detects a source of input of image data according to a network I/F or a parallel bus I/F. An image-memory access control section transmits the image data input from each of the functional units to a memory group and also transmits the image data stored in the memory group to the functional unit. A system controller controls the overall apparatus and also controls the image-memory access control section according to the input source of the image data to determine an order of transmitting the image data to the memory group.

Image processor

The image processor comprises a switch that divides image data into m&#xd7;n pixels, having n lines with m pixels per one line; a group of line memories that store the divided image; a compression device which batch compresses the image data of m&#xd7;n pixels. Further, a command control unit provides control so as to send the (n&#x2212;1) lines of image data among m&#xd7;n pixels of image data to the group of line memories, and the remaining one line of image data directly to the compression device, and to send the m&#xd7;(n&#x2212;1) pixels of image data stored in the line memories to the compression device.

In a short-range on-vehicle radio communication system having in-car radio communication function, a two-way transmission antenna for radio communication is arranged at a panel portion outside a sheet metal chassis of a car navigation unit. As a result, the communication area becomes large, signals including those from a cellular phone of low radio communication output power are easily received, and it is possible to save manufacturing cost.

Short-range automobile wireless communication device

The image processing apparatus is provided with a plural memory controllers, each of which controls a RAM. The memory controllers are connected to an SIMD type arithmetic processing section. A control register is connected to the memory controllers. The control register controls transfer of image data between the RAMs and the SIMD type arithmetic processing section.

Documents are read and the read image data and the information about the size of the document is stored in a memory. A factor of enlargement/reduction is calculated based on the stored size information. An image processorinterpolates the image data based on the calculated enlargement/reduction factor and reproduces the enlarged/reduced document.

Apparatus and method for processing images, and computer product

The image processing apparatus comprises a reading unit which simultaneously reads image data from two, an obverse and a reverse, surfaces of a document, and a compressing unit which compresses received image data. The apparatus further comprises a controlling unit which orchestrates a flow of image data from the reading unit to the compressing unit in such a manner that the image data corresponding to the obverse surface and the reverse surface is input into the compressing unit at different timing.

Image processing apparatus

An obstacle detection device includes: a hyperboloidal mirror contained near a tip of a pole mounted at the corner of a vehicle; an image pickup unit for picking up an image shown in the hyperboloidal mirror; a signal processing circuit that performs an image signal processing for allowing easy viewability of the image picked up by the image pickup unit; and a display unit that is mounted in the vehicle compartment of the vehicle and displays the image signal processed by the signal processing circuit.
