  • Patent number: 4569580
    Abstract: A flash device for a photographic camera either inhibits a flashing action or shifts the control mode of the camera from flash photography to daylight photography in cases where the object to be photographed is located outside of an adequately operable distance range. A pre-flashing action detects a distance to the object when a main capacitor is charged to a given level before the capacitor is fully charged for flash photography. Then flash photography is performed at an aperture value determined on the basis of the detected distance when the distance is within the adequately operable distance range. When the detected distance is outside of the adequately operable distance range, the main capacitor is further charged for an increased flashing power. Then the distance to the object is again detected by a second preflashing action before flash photography is carried out at an aperture value determined on the basis of the distance detected by the second pre-flashing action.

  • Patent number: 4559644
    Abstract: An apparatus and method for reading, processing, storing and later printing out stored data from an original document in which undesired data portions are prevented from being recorded. Portions of the printed original image which are desirably retained and recorded are printed with solid lines, while image portions, for instance, ledger lines, which are desirably not retained and recorded, are printed as optically fine discontinuous patterns. The original thus printed is scanned line by line. The analog signal which is produced by the scanning device has high frequency portions when an optically fine discontinuous pattern is scanned. These portions are eliminated by low-pass filtering or by determining the degree of correlation between the sensor output signal and stored data representing the optically fine discontinuous patterns.

  • Patent number: 4494044
    Abstract: The disclosed computer type electronic flash device has a light measuring circuit which produces a flash terminating signal upon receipt of light reflected from an object to be photographed. Connected to this light measuring circuit is a control circuit which renders the former inoperative after the lapse of time required by a flash tube for terminating emission of a flash light. This arrangement precludes a commutating circuit from being rendered conductive again after termination of flash by the flash tube.

  • Patent number: 4492985
    Abstract: An input and/or output unit which reads or records a picture utilizing a scanning beam in which sampling positions of picture elements in a main scanning direction are uniformly spaced. A first clock signal is produced which is at least three times as high in frequency as an output sampling clock signal. The first clock signal operates a counter, the output of which is compared with the output of a ROM. The ROM is addressed by a counter which is incremented by output comparison pulses. The output of the comparator is also utilized as the output sampling signal. Numerical values are stored in the ROM such that the output pulses from the comparator occur at times corresponding to constant sampling intervals of the scanning beam along a scanning line.

  • Patent number: 4484807
    Abstract: A flash photographing device of the type which detects the distance up to an object by a preliminary flash emission so as to control the diaphragm according to the detailed object distance, while the light adjusting level of the light adjusting speed light device is set according to the detected object distance. In the case of a flash photographing device of this type, a proper exposure can be guaranteed when a detected object distance is within the range of the operational engagement of a light adjusting circuit, while the exposure is improper when the distance is beyond the range. The arrangement of the present invention provides a flash photographing device of the above-described type which controls the diaphragm at the smallest aperture value of the lens independently of the value of a detected object distance when the detected object distance is beyond the range of operative engagement.

  • Patent number: 4466123
    Abstract: An apparatus for producing a contour line pattern image from an original image such as a character or the like recorded in binary format in a memory couples image element points equidistantly isolated from edges of the original image and thereby forms a contour line pattern curve. The coupling of the equidistant points and the formation of the contour line pattern curve in the contour line pattern image are repeatedly carried out. Smudged areas of the contour line pattern image are detected and eliminated and missing portions of the contour line pattern image are regenerated.

  • Patent number: 4440513
    Abstract: A character shaping device includes a tablet or the like upon which characters are written or drawn, and a device for determing distribution functions for the character as projected in the x- and y-directions. From this information the "center of gravity" of the character is calculated, and the x- and y-dimensions of the character are detected to determine the character area. The image is then centered within a normalization area and enlarged or reduced in size according to scale factors dependent upon the relative dimensions of the character area and the normalization area, to obtain a well balanced and sized character which may then be printed along with other characters to form sentences on a printed document or the like.

  • Patent number: 4422153
    Abstract: An oblique projection original is formed by deforming an orthogonal projection original in such a manner that a rectangular original is transformed into a trapezoidal original by compressing the orthogonal projection original by thinning scanning lines in a horizontal direction. In addition, predetermined bits in each scanning line are thinned in a vertical direction, and each line is compressed by reducing first and last portions of each line by half the number of bits thus thinned. Finally, white bits are inserted at the first and last portions of each scanning line to complete each scanning line.
