摘要： An object recognition system utilizes a mask locator for extracting a mask area (M) from within a subject image in order to recognize the mask area (M) with a subject image. The mask locator (40) refers to density gradient directional images respectively converted from an image size template and the subject image, and analyzes these density gradient directional images particularly with respect to the density gradient directional values (θT, θS) assigned to each pixel in each directional images to obtain parameters linking the image size template to the mask area (M) to be registered with the image size template. The mask locator has a vote module (60) which gives candidates for the center of the mask by varying the parameters and votes on the candidates. Based upon the number of votes for the candidates, a detection module (70) designate one of the candidates having a maximum vote number as the center of the mask area (M), thereby determining the mask area (M) around thus designated candidate within the subject image for exact recognition of the object in the subject image.

摘要： Disclosed is a distance measuring apparatus for measuring a distance to a target object also its shape precisely without influence of noise, which is applied to a invader monitoring system. This apparatus comprises a clock signal generator unit, a modulated light projector unit, a light receiver unit, and a demodulator unit, and obtains a range image presenting signal levels changing according to the distances to the objects including the target object by irradiating light onto the objects and receiving reflected light. In the demodulator unit, the range image is processed for evaluating and removing noise components, for interpolating and averaging noise removed region, and for selecting the target object region. Those processes are carried out from the following point of view, the variation of the distance signal levels, the received quantity of light, and the variation of the received quantity of light. Thus a range image without no noise and including substantially only the target object data is obtained, and therefore it is possible to measure a distance to the target object and its shape precisely without influence of noise.

摘要： An image processor is provided, which has the capability of detecting an object such as a human face from an image taken against the sun with high accuracy. An image signal provided from an image pickup unit is adjusted at an analog gain by an image adjuster. An out of the image adjuster is converted into a digital, and store in a memory. A feature of the object is extracted from this digital image data to detect an object area in the image. When the object area is not detected, an analog-gain controller sends that the image signal provided from the image pickup unit is adjusted at a different analog gain. Thus, the treatment of detecting the object area is repeated at different analog gains.

摘要： Automatic tracking lighting equipment for automatically tracking a target to be illuminated. A spotlight is supported for pivoting in horizontal and vertical directions on a ceiling surface. A horizontal drive mechanism changes the horizontal angle of the spotlight and a vertical drive mechanism changes the vertical angle of the spotlight. A CCD camera picks up the image of a target area to be illuminated. An image recognition unit processes the image from the CCD camera to recognize the target to be illuminated and to specify its coordinates. A coordinate calculation unit calculates how far to move the spotlight based on a distance of the target to be illuminated. A movable control unit converts the output of the coordinate calculation unit into drive signals for the horizontal drive mechanism and for the vertical drive mechanism and outputs drive signals to pivot the spotlight in a desired direction.
