Abstract: In a method for extracting an object image, an extraction area for extraction of a candidate for a predetermined object image from an image is determined. The center point of a view window, which has a predetermined size, is caused to travel to the position of the candidate for the predetermined object image. The extraction area is determined in accordance with the size and/or the shape of the candidate for the predetermined object image, the center point of the view window being taken as a reference during the determination of the extraction area. The extraction of the candidate for the predetermined object image is carried out by using a neural network. Even if a plurality of object images, which are to be extracted, are embedded in a given image, the object images are extracted efficiently such that an object image, which has already been extracted, may not be extracted again.

Abstract: An optical beam scanning apparatus of this invention includes rotary optical means (3,7) rotating on an axis of rotation and guiding optical beams incident parallel to the axis of rotation to a direction rectangular to the axis of rotation so as to scan a cylindrical surface inside a cylinder (1) by rotating the optical beams in a peripheral direction. An anamorphic optical system (7) rotating on a straight line substantially coinciding with the axis of rotation, for example, is disposed as optical beam rotation means on the incident side of the optical beams of the rotary optical means, and the optical beams incident into the rotary optical (7) means are rotated at the same rotating speed as that of the rotary optical means (3) on the straight line as the axis of rotation. According to this structure, a plurality of optical beams do not corss one another on the cylindrical surface when they are used, but form substantially parallel beam lines. Accordingly, multiple beam scanning as well as high speed recording becomes possible.

Abstract: An East-West switching transistor (Q1) is coupled between a flyback transformer primary winding (W1) and a horizontal deflection output transistor circuit (100,Q2) to control retrace energy to obtain an East-West modulation of the deflection current amplitude as required for East-West pincushion raster correction. The East-West switching transistor isolates a retrace resonant circuit (100) that includes a horizontal deflection winding (L H ) from a flyback resonant circuit (W1) that includes the flyback transformer during a portion (t2,t3-t4,FIG.2d) of retrace. The deflection winding is coupled to a common conductor to permit the use of a retrace voltage sample(V4), developed in the deflection winding and coupled to the East-West switching transistor, to control the switching operation in a manner that bypasses the flyback transformer. A resistor (R1) coupled in series with the primary winding develops a voltage (VC7), during trace, that is indicative of beam current. The resistor voltage is coupled to the East-West switching transistor to prevent beam current variation from causing raster width variation.
