摘要： An apparatus for document browsing, specifically for document retrieval systems. The browsing apparatus enables users to see multiple document pages on the same screen at the same time in a first mode and to see a bundle of pages on a screen in a second mode. The images shown on the screen are produced internally according to the user's commands. The pages may be flipped in either direction and selected pages may be marked for later printing instructions.

摘要： For halftone digital image data, an edge portion of the image is extracted for each pixel, and based on a density of each pixel or an average density of each group of a plurality of adjacent or neighboring pixels, there are extracted pixels of a background other than the edge portion of the image. Thereafter, the image data is subdivided into a plurality of blocks each including a predetermined number of pixels. Based on distribution states of the pixels of the block judged to belong to the edge and those of the block judged to belong to the background, a domain recognition is conducted to determine whether the block is a binary block or a halftone block. In addition, for each block, a state of areas in blocks encircling the block is examined such that depending on the state, an expansion/contraction processing is repeatedly achieved a predetermined times for the halftone domain, thereby separating the image data into a binary domain and a halftone domain in a real-time fashion.

摘要： In a control system for a brushless motor comprising a power source, a plurality of driving coils and contactless switching elements for intermittently supplying voltage across the power source to the driving coils in response to rotor position signals, rotor position signals are chopped by a chopping signal in which a ratio of a high level period to a low level period can be changed, and a portion of the contactless switching elements is driven by the chopped rotor position signals, thereby controlling the rotating speed of the brushless motor.
