Abstract: An accident judgment device (105) judges whether or not an accident has occurred based on a detection signal of an impact sensor (104). Upon judging that an accident has occurred, an image saving device (106) extracts an image within several seconds before and after occurrence of the accident from a ring buffer (103) to save the same in a save memory (107). Upon judging that the accident has occurred, an image-record requesting device (108) transmits an image-recording request to a drive recorder (10) of target vehicles existing in the vicinity of the accident spot. Upon receiving the image-recording request, an image saving device (106) of the drive recorder (10) on the target vehicle extracts the image within several seconds before and after occurrence of the accident from the ring buffer (103) to save the same into the save memory (107).

Abstract: A wide-field image input device that joins a series of partial images obtained by continuously imaging an imaging object by an imaging device while the imaging device is manually scanned by a user, thereby generating a wide-field image, includes: a camera position/posture estimation unit for receiving a partial image series and calculating a change state of three-dimensional position and posture of the imaging device as time-series camera position/posture information; a deformation parameter estimation unit for calculating a geometrical deformation parameter between adjacent partial images from the camera position/posture information; an image joining unit for joining the partial images by using the geometrical deformation parameter so as to generate a wide-field image; and a camera scan error detection unit for detecting motion of the imaging device according to the camera position/posture information and outputting a camera scan error detection signal when an error is detected.

Abstract: Provided is an image processing system that can uniquely identify a motion vector for each pixel of an interpolation frame and accurately identify a motion vector. A motion vector candidate selection unit (301) sequentially selects predetermined motion vector candidates in an interpolation frame. A differential image generation unit (302), a binary image generation unit (303) and an area image generation unit (304) generate a differential image, a binary image and an area image, respectively, based on a selected motion vector candidate. For each pixel of the interpolation frame, a motion vector determination unit (305) identifies a motion vector candidate with which a pixel value of a pixel in the area image corresponding to the pixel is the largest as a motion vector. A pixel value determination unit (306) determines each pixel value of the interpolation frame by using the motion vector identified for each pixel, thereby generating an interpolation frame.

Abstract: Even when an enlarged image is deteriorated due to a block noise or color mixture, the contour in the enlarged image is sharpened and a quality of the image is improved. A contour extracting unit 103 determines a pixel indicating the contour in an interpolation image, using brightness gradient strength and a brightness gradient direction.

Abstract: A data processing unit calculates image conversions parameters corresponding to each partial image, geometrically converts photographed partial images on the basis of a current partial image based on the calculated image conversion parameters, and combines them to generate a mosaic image. Also, a display device displays each current partial image, and at least part of the generated mosaic image.

Abstract: [PROBLEMS] In a system for converting a low resolution image to a high resolution image, it is difficult to carry out processing to generate a high resolution image for each frame in real time using temporally continuous frame images. [MEANS FOR SOLVING THE PROBLEMS] An image processing system includes a conversion parameter calculation unit 101, an initial image generation unit 102, a high resolution image generation unit 103, and an input image and conversion parameter storage unit 110, and converts the high resolution image generated at the previous frame in accordance with a current frame based on the conversion parameter for the current frame with respect to the previous frame so as to perform high resolution image generation processing of the current frame with the converted image as an initial value.

Abstract: A data processing device calculates an image conversion parameter corresponding to each partial image. According to the image conversion parameter calculated, a partial image which has been imaged according to the current partial image is geometrically converted. The images are combined to generate a mosaic image. Moreover, the current partial image and at least a part of the mosaic image generated are displayed on a display unit.
