A camera system (100) comprises an image capturing device (102), object detection module (204), object tracking module (206), and match classifier (218). The object detection module (204) receives image data and detects objects appearing in one or more of the images. The object tracking module (206) temporally associates instances of a first object detected in a first group of the images. The first object has a first signature representing features of the first object. The match classifier (218) matches object instances by analyzing data derived from the first signature of the first object and a second signature of a second object detected in a second image. The second signature represents features of the second object derived from the second image. The match classifier (218) determine whether the second signature matches the first signature. A training process automatically configures the match classifier (218) using a set of possible object features.

An information communication method of transmitting a signal is provided that uses a change in luminance. The method includes determining a pattern of the change in luminance by modulating the signal to be transmitted, and transmitting the signal by a light emitter changing in luminance according to the determined pattern. The pattern of the change in luminance is a pattern in which one of two different luminance values occurs in each arbitrary position in a predetermined duration. The determining a pattern of change in luminance includes dividing the predetermined duration into four duration units, so that one of two different luminance value occurs in one duration unit of the four duration units and the other luminance value of the two different luminance value occurs in three duration units of the four duration units, the three duration units are other than the one duration unit.

A color-image reproduction apparatus reproduces a color image on the basis of digital image data which are obtained through detection of an image by visible light detection elements and an infrared detection element. Visible image data are extracted from the image data, and infrared-containing image data are extracted from the image data. Brightness information is extracted from the visible image data or infrared-containing image data. An infrared component is removed from the visible image data. Color information is extracted from the visible image data from which the infrared component has been removed. The brightness information and the color information are combined so as to generate a quasi color image.

PROBLEM TO BE SOLVED: To provide a vehicle rear display device capable of facilitating backward movement or parking. SOLUTION: A wide angle camera 12 is provided at a low position of the backward of a vehicle, and a narrow angle camera 11 is provided at a high position. A vehicle condition detecting device 20 detecting a condition of the vehicle, a display switching device 30, and a display device 40 are installed. In backward parking, the vehicle condition detecting device 20 detects a vehicle condition from the moving distance of the vehicle, vehicle speed, braking volume and the like, and the display switching device 30 switches a required image corresponding to the condition. For example, in the first half of backward parking, the wide angle camera 12 is actuated so as to display a wide area image at the backward of the vehicle (backward outline), according to the moving distance. In the last half of backward parking, the narrow angle camera 11 is actuated so as to display a narrow area image of the backward of the vehicle (backward details). Since a driver can obtain an appropriate image in a parking process, backward parking can be done easily and safely. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To reduce an increase in calculation overhead and effectively reduce the number of false detection or non-detection of an obstruction such as a pedestrian in obstruction detection processing by an obstruction detection system. SOLUTION: A detection result comparison means 160 includes a control means which issues an execution instruction for adaptive control when there is a conflict between the detection result of a distance/direction/relative-speed detection means 150 and the detection result of a three-dimensional-object detection means 110. The detection result comparison means 160 outputs a feedback signal S1 meaning the execution instruction of the adaptive control to a detection range limiting means 141 and a beam direction/shape calculation means 142. The beam direction/shape calculation means 142 changes a weighting coefficient A m (a complex number; 1≤m≤M) of a reception signal of each individual antenna constituting a millimeter-wave radar in accordance with the detection result of the three-dimensional-object detection means 110. A radar beam control 122 generates a total sum about search data (the reception signal) for each direction on the basis of the given weighting coefficient A m . COPYRIGHT: (C)2006,JPO&NCIPI
