摘要： A feature extraction unit (23) extracts features of an object of interest included in an image. A local region setting unit (24) sets a local region that includes a feature group required to obtain the shape of the object and a local region that includes a feature group required to obtain the positional relationship. A feature vector generation unit (25) calculates feature vector data in the set local regions. An object recognition unit (26) determines which of different objects the object of interest is, on the basis of the feature vectors.

摘要： An area-type beam splitter is disposed across the optical path of an imaging optical system. Photodetector arrays are located across the optical path portions divided by the beam splitter. The photodetector arrays in the respective optical path portions are arranged in different positions from one another in such a manner that images different from one another in imaging performance will be read by the respective photodetector arrays.

摘要： When an image from a scanner or an external apparatus is to be printed out, in order to achieve both high color reproducibility and high gray reproducibility, a black signal is extracted from an input color image signal, the ratio of the extracted black signal to the color image signal is changed in accordance with an input instruction, and an output operation is performed in accordance with the extracted black signal and the color image signal. When a color image signal is formed by scanning an image, a black signal is extracted from the color image signal, a high-frequency component of the extracted black signal is removed, and an output operation is performed in accordance with the black signal, from which the high-frequency component is removed, and with the color image signal.

摘要： A sharpness-determining device is disclosed in which an object image generated on a prescribed focal plane of a photolens is once again projected by a second projecting optical system behind this focal plane into two object images which are not located one above another and are based on light bundle sections which are split up symmetrically relative to the optical axis of the photolens; light-sensitive elements are respectively arranged at the points at which these object images are once again projected by the second optical system; a sharpness state of the photolens is determined by using these light-sensitive elements to detect the relative spatial relationship of these object images projected once again. The sharpness-determining device comprises a beam-splitting device which is arranged in the second optical system and splits up a light bundle, coming from the exit pupil of the photolens, into a central section and an edge section. Using this arrangement, it is possible by means of the second optical system to obtain an object image which is required in accordance with the varying f-number of the exit pupil of the photolens, or an object image which simultaneously allows the use of a further determining process with this device.

摘要： Disclosed is a light splitter in which a number of minute inclined surfaces inclined with respect to the surface of a parallel planar glass is formed. At least part of a light beam having entered the light splitter travels while being totally reflected by said surface and said inclined surfaces and the remainder of the light beam travels without being totally reflected by said inclined surfaces.

摘要： A phase type diffraction grating and a microprism for splitting the light beam from an objective lens into three light beams. The three light beams are split in one direction by the diffraction grating and are directed onto three rows of line sensors disposed on the same plane. In the two optical paths between the diffraction grating and the line sensors, there is disposed an optical path length difference imparting element for forming on the line sensors images at a predetermined focal plane of the objective lens and planes forward and rearward of the predetermined focal plane. Thus, the line sensors detect the images at the predetermined focal plane and at planes forward and rearward of the predetermined focal plane.
