摘要： Provided is a projection system that easily and appropriately reduces the geometric distortion of the image projected on the projection plane. The projection circuitry 3 of the projection system 1000 projects a test image onto the projection plane. The three-dimensional shape measurement circuitry 4 measures the three-dimensional shape of the projection plane. The controller 200 generates a control signal. Based on the measured three-dimensional shape data, the projection image adjustment circuitry 1 performs correction processing and rotation processing on a test, in accordance with the control signal, such that the geometrical image distortion is reduced as viewed from the user's viewpoint.

摘要： An information reception device is provided with: operation surface which is adjusted to produce a characteristic index vibration by an object contact; a storage device stores candidate information (candidate information is related with the index vibration) which serves as a candidate of input information; a microphone which acquires observation information according to observation of the actual vibration arising in the surrounding environment; and a CPU. The CPU (selecting part) judges whether or not the index vibration exists in the observation information acquired. When the CPU judges that the index vibration exists, the CPU selects the candidate information which is related with the index vibration as the input information.

摘要： In an object detection apparatus 1, a window definer 11 defines a window relative to the location of a pixel in an input image 20. A classification value calculator 13 calculates a classification value indicative of the likelihood that a detection target is present in the window image contained in the window based on the feature data of the detection target. A classification image generator 14 arranges the classification value calculated from the window image according to the pixel location to generate a classification image. An integrator 15 integrates the classification image and a past classification image 42 generated from a past input image input prior to the input image 20 to generate an integrated image 45. A determiner 16 determines whether the detection target is present in the input image 20 based on the integrated image 45.

摘要： The object detection device 1 detects an object being recognized (such as a pedestrian) in a frame image 42, and identifies an area 42a where a detected object which is detected in the frame image 42 is present. A frame image 43 is input after the frame image 42. The object detection device 1 detects the object being recognized in the frame image 43, and identifies an area 43a where a detected object which is detected in the frame image 43 is present. When a distance from center coordinates 42b of the area 42a to center coordinates 43b of the area 43a is smaller than a reference distance, the object detection device 1 determines that the detected object which is detected in the frame image 43 is identical to the detected object which is detected in the frame image 42.

摘要： Provided is a projection system that sets an arbitrary three-dimensional shape as a projection target and properly corrects geometric distortion of a projected image even when a user's viewpoint is not fixed. A projection unit of the projector apparatus projects a test image for first adjustment. A three-dimensional shape measurement unit measures the three-dimensional shape of the projection target. An image capturing apparatus captures the test image for first adjustment projected by the projection unit to obtain a captured image for first adjustment. A projected image adjustment unit (1) performs first adjustment processing for correcting an image such that geometric image distortion viewed from an imaging point, at which the captured image for first adjustment has been captured, is reduced, based on a captured image for first adjustment obtained by the image capturing apparatus, and (2) performs second adjustment processing for correcting the image such that the geometric image distortion is reduced based on a state in which the image adjusted by the first adjustment processing is projected by the projection unit.

摘要： In an object detection apparatus (1), a window setting unit (12) extracts a window (52) from an edge image (22), to thereby generate an ordinary window image (23). When an edge strength of the ordinary window image (23) is not larger than a usage reference value, a used image determination unit (15) determines to use the ordinary window image (23) for calculation of an identification value (30) indicating a degree of presence of a pedestrian in the window (52). When the edge strength of the ordinary window image (23) is larger than the usage reference value, a pixel value correction unit (13) generates a corrected window image (24) having an edge strength smaller than that of the ordinary window image (23) from the ordinary window image (23). When the edge strength of the corrected window image (24) is not larger than the usage reference value, the used image determination unit (15) determines the corrected window image (24) to be used for calculation of the identification value (30).

摘要： Even when a high-performance imaging apparatus is not used, luminance unevenness and color unevenness of an image (video) projected on a projection plane by the projection type projector apparatus are appropriately reduced. Using a coefficient Br (0≤Br≤1) set by a coefficient setting unit, the projection system obtains, based on the gamma characteristic of the entire system of the projection system, a target image for reducing the number of pixels saturated when the image is projected. Then, the projection system performs correction processing using the obtained target image based on the gamma characteristic of the entire system of the projection system and a white value. This reduces the number of saturated pixels of the projected image in the projection system. Furthermore, even in a case or similar cases when a captured image obtained by capturing a projected image has a bad S/N ratio, image projection processing that does not cause a user discomfort in viewing the projected image (or captured image) is achieved.

摘要： An object detection device detects an object being recognized (such as a pedestrian) in a frame image, and identifies an area where a detected object which is detected in the frame image is present. A frame image is input after the frame image. The object detection device detects the object being recognized in the frame image, and identifies an area where a detected object which is detected in the frame image is present. When a distance from center coordinates of the area to center coordinates of the area is smaller than a reference distance, the object detection device determines that the detected object which is detected in the frame image is identical to the detected object which is detected in the frame image.
