摘要： An image signal processing apparatus to realize signal processing system and apparatus constitution, where an image signal inputted using a photoelectric conversion element such as a CCD or a contact type image sensor is obtained in circuit constitution of small scale with high picture quality. In order to solve the problems, data width of a signal referred to in a shading corrector, an MTF corrector and an error diffusion circuit is made b + f + j ≦ 8 per one pixel. Or error component commonly possessed by plural pixels (N pixels) in the error diffusion circuit is made b + f + j' ≦ 8 , data width per one pixel being made j' = j/N . Image signal processing is realized in this constitution, thereby data width of a signal referred to in respective signal processings is reduced, and an image signal satisfying accuracy of signal processing sufficiently and having high picture quality can be obtained. For example, when a circuit is constituted by LSI, the memory section can be easily mounted on the same LSI. A memory required in the image signal processing can be made 8 bits per one pixel and a cheap memory constitution can be utilized.

摘要： A communication interface apparatus is provided for extending a communication available distance, suppressing the influence of a power receiving circuit on a transmitter/receiver circuit (3), and reducing the cost. The transmitter/receiver circuit is configured in a balanced circuit to enhance the driving capability, so that a sufficient amplitude can be ensured even if a power receiving circuit (8) provides a low received voltage. A low pass filter (LPF) is added in front of the power receiving circuit to eliminate electrical interference between the power receiving circuit and the transmitter/receiver circuit, resulting in improved input impedance frequency characteristics of the power receiving circuit. The LPF is connected to both plus and minus terminals of the power receiving circuit, and bypass capacitor is shared by plus and minus inputs, thereby providing well balanced operation characteristic. A Zener diode may be utilized in the LPF to form a two-stage stabilizing circuit, so that an IC-based voltage regulator can be used even with a high input voltage provided from if the power receiving circuit.

摘要： A facsimile apparatus has a transparent plate on which a document may be located (11). The document is then scanned by a scanner (31) which includes electronic solid state light generation means (32) e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector (33). An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternatively, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from a store (22) and an image printed thereon by a heat transfer system in which a film (24) of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the store (22). The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner (31) fixed.
