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 Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated.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

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.ltoreq.8 per one pixel. Or error component commonly possessed by plural pixels (N pixels) in the error diffusion circuit is made b+f+j'.ltoreq.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： An LED lighting device can compensate a brightness change and a color change caused by a temperature change and exhibit an in-plane uniform luminance and color. A lighting device includes: at least one line connected in parallel, a constant voltage source for applying a constant voltage to the line, an ON/OFF controller, and a current detector for measuring a value of current flowing in the line. The line is formed by one or more light-emitting diodes and a switch for turning ON/OFF the current flowing in the light emitting diodes connected in series. According to the current value of each of the lines measured by the current detector, the ON/OFF controller controls the ON/OFF period of the switch of each of the lines.
