摘要： A block noise detector has a spatial difference calculator that calculates differences between values of adjacent pixels. A spatial difference comparator detects edges by comparing the calculated differences. Eight counters count edges detected at different groups of positions spaced eight pixels apart in each horizontal line. The maximum count and the group of positions at which it occurs are detected at the end of each horizontal line to detect block noise and the positions of the block boundaries. The block noise detector is small in size because it only has to count edges in one line at a time, and detects edges accurately by comparing the difference at a given position separately with differences to the left and differences to the right.

摘要： A parking assist apparatus includes a CPU for obtaining image data from a camera mounted on a vehicle, an image memory for storing the obtained image data as recorded image data, and an image processor for recognizing an object based on the image data. The image processor determines when to display a parking assist image to reveal an area hidden as a blind spot of the camera when the recognized object is in the blind spot of the camera and displays the parking assist image combining both current image data and the recorded image data for the area currently hidden as the blind spot of the camera, together with an indicator indicating the current position of the vehicle superimposed on the display.

摘要： A first intermediate image generating means (1) generates an intermediate image (D1) by extracting a component of an input image DIN in a particular frequency band; a second intermediate image generating means (2) generates an intermediate image D2 having a frequency component higher than the intermediate image (D1); a first intermediate image processing means (3M) generates an intermediate image (D3M) by amplifying the pixel values in the intermediate image (D1); a second intermediate image processing means (3H) generates an intermediate image (D3H) by amplifying the pixel values in the intermediate image (D2); and an adding means (4) adds the input image (DIN) and the intermediate image (D3M) and the intermediate image (D3H) together to obtain an output image (DOUT). A first amplification factor (D3MA) and a second amplification factor (D3HA) are determined according to pixel values in the input image (DIN). Even if the input image includes a fold-over component on the high-frequency side or does not include an adequate high-frequency component, an enhanced image can be provided without causing overshoot.

摘要： Systems for determining a movement amount detect a steering angle of a moving body on which a camera is mounted and extract matching inspection areas of a prescribed shape and size from frames captured by a camera. The systems rotate the inspection area of a second frame relative to the inspection area of a first frame, the rotation based on the detected steering angle. The systems execute pattern matching between the inspection areas and calculate positions of subject points that correspond to identical characteristic points in each frame. The systems, methods, and programs determine the movement amount based on a displacement amount between the calculated subject point positions.
