摘要:
An image data compressing apparatus comprises a color selecting unit, a data separating unit and a data compressing unit. The selecting unit selects an arbitrary color contained in an original map image. The separating unit separates the original image data into a modified color data and a selected position data. The compressing unit compresses these data separately from each other to improve data compression efficiency. The modified color data may be data in which a color of a background portion is made equal to a color of a road, and the background color may be a color which is most popularly used.

A driver's gaze distribution is detected. Based on the detected distribution, an image corresponding to a driver's visual-field is extracted from images photographed by a front monitor camera and is accumulated. A first driver's gaze probability distribution necessary for steering operation is computed based on the accumulated images, and a second driver's gaze probability distribution that is expected is computed based on visual characteristics within the images. An ideal gaze probability distribution is obtained by adding up the first and the second probability distributions. Presence of a risk is determined when the difference between the driver's gaze and the ideal gaze probability distribution becomes a given threshold. A windshield display or a speaker outputs the determined result.

An image processing apparatus draws an image, stores the drawn image in a memory, reads image data from the memory along a raster direction, and executes a processing operation required for a display with respect to the read image data to output the processed image data to a display device. A display processing unit executes a processing operation including a coordinate calculation with respect to the image data read out along the raster direction. As a result, the image can be formed at high speed even under transition state of displayed images.

A dynamic contour extracting means detects, using a dynamic contour extraction method generally known as SNAKE, a contour of a recognition object included on an image by the following steps: a curve with control points is disposed in an image; an internal energy Eint indicating smoothness of the curve, an image energy Eimage, and an external energy Eext are summed up; and the curve is modified so that the summed total energy becomes the minimum. Here, a template is stored for including disposition information of primary control points that are bound to be moved only in a vertical or horizontal direction based on a road shape. The dynamic contour extracting means moves the primary control points based on the template. The primary control points can be rapidly moved owing to their limited movement direction.

When display data for both odd-numbered and even-numbered scan electrodes in an electroluminescent display are both actuating data, the brightness of electroluminescent elements connected to the odd-numbered electrode is adjusted by adjusting the timing for starting the application of the actuating voltage and the brightness of electroluminescent elements connected to the even-numbered electrode is adjusted by adjusting the timing for terminating the application of the actuating voltage. Moreover, electric charge in the EL elements is retained by maintaining the application of the actuating voltages during scanning operations.

A lock release apparatus in a vehicle includes a vehicle unit and a portable device, for an exchange of the first and second reference signals transmitted therebetween from the portable device through human body of the driver toward the right and left hands of the driver onto the first and second interfaces. The signals received by the interfaces are used to set the first and second determination conditions. At a time of a shift lever operation, an interface on a shift lever is used to receive the first determination signal for determining the first determination condition, together with the second determination signal from the other interface for releasing the lock of the shift lever.

An operation control system includes a transmitter circuit, a transmitter interface, an engine start button switch, a receiver unit and an engine ECU. The transmitter circuit generates a transmission signal and the transmitter interface inputs a communication signal to an operator by converting the transmission signal. The receiver unit receives the communication signal through the operator, when the operator touches the engine start button switch. The engine start button switch detects in-blood alcohol concentration of the operator. The receiver unit generates and applies an engine start control signal in response to output signals of the receiver unit indicative of the operator's engine start operation and alcohol detection result.

An identification apparatus and an identification method are disclosed. According to the identification apparatus and method, an identification code is created by combining multiple information items. Further one or more of multiple tactile information items that represents the created identification code is produced based on a correspondence relation between the multiple tactile information items and the multiple information units. Further, identification is performed based on determining whether the created identification code is equal to the identification code that is actually input in response to the producing of the one or more of the multiple tactile information items that represents the created identification code.
