  • Patent number: 5987166
    Abstract: It is an object to provide an image processing apparatus which can obtain an image reproduction that accurately corresponds to an original color when an ordinary color original is read and which can obtain an accurate marker edition result when a marker original is read. When a color scanning mode to read the color image is selected, an original ground removal by a prescan is not performed. When a marker edition scanning mode to read the marker original is selected, the original ground removal is executed. Thus, a color reproduction which accurately corresponds to the original is executed in the color scanning mode. In the marker edition scanning mode, the color recognition of the marker color is accurately performed without being influenced by the ground color.

  • Patent number: 5974171
    Abstract: An image processing apparatus prevents the misdetermination of a read color and allows correct marker edition. A marker registration circuit reads and register color data marked by a predetermined color marker and a color determination circuit compares the color data registered and the read color data at the reading of the document sheet to determine a color code of the marker color. An area determination circuit determines whether an area being read belongs to a normal area, a line area or a paint area and an output color determination circuit determines a color to be outputted in accordance with the color code and the area being read.

  • Patent number: 5959644
    Abstract: An image is recorded by repeating a recording operation which includes a main scanning operation performed by moving a recording head in which recording elements are arrayed in a direction perpendicular to a direction in which the recording elements are arrayed. A vertical scanning operation is performed by moving a recording medium in a direction perpendicular to the horizontal scanning direction through a distance corresponding to a recording width after the horizontal scanning operation is completed. When image data having a width narrower than a maximum recording width of the recording head is recorded, for example when a reduction recording is performed, a number of image data having the narrower width are combined so that image data having the maximum recording width can be recorded in one recording operation using the plurality of recording elements.

  • Patent number: 5855512
    Abstract: According to a method of programming a TV-game of the present invention, the event variation process 40 is added between processes of the TV-game program. Therefore, one of the processes of the TV-game program or the event variation process 40 is selected according to a situation of a TV-game scenario. Namely, the event variation process 40 is executed only when the event variation process 40 is selected. The event variation process 40 is not executed when anther process is selected. Therefore, the CPU load is light, because the event variation process 40 is not executed at each time. Further, even if the characters of the TV-game are many, the character motion is not paused. Therefore, the TV-game can include a variety of situations, because the steps in the TV-program are not cut off.

  • Patent number: 5768484
    Abstract: A printing apparatus capable of printing a mirror image without increasing the apparatus size. Print data for one band image is stored into an image memory 7 in accordance with an address (in an ascending order) generated by an address counter 103. After storing the print data for one scanning by a print head 101 has been completed in the image memory 7, the print data is read out in accordance with an address (in an descending order) generated by an address counter 104 from the image memory 7, and outputted to the print head 101. At this time, since print data which has previously been used for printing is used no longer, the address counter 103 is set to generate an address in the descending order, and storing of the next print data is made in parallel to the printing. When the printing based on the print data in one scanning has been completed, an address counter 106 is set to generate an address in the ascending order for the next image printing.

  • Patent number: 5202199
    Abstract: This invention relates to the battery and its marking process with desired designs marked on the surface of a metal container consisting of case and cover containing battery system elements within and an external metal jacket by scanning pulse laser beams and leaving a certain arrangement of dotted irradiated traces. The above marking process is suitable for inscribing finely detailed marks on small-sized batteries extensively marketed these days. Also, this process can handle frequent changes of inscription to be marked quickly and economically without losing superior clarity. Moreover, the industrial benefit will be further increased by combining it with the existing mechanical marking process, using convex dies for stamps.

  • Patent number: 4583129
    Abstract: A color TV signal playback apparatus capable of applying H (horizontal sync) period compensation and color sequence compensation to a color TV signal stored in a magnetic tape. A 1-H delayed reproduced color signal and a non-delayed reproduced color signal are switched from one to the other in response to a color sequence compensating signal. The selected reproduced color signal is multiplexed with a reproduced luminance signal to prepare a composite video signal. A signal produced by delaying the composite video signal by a period of time equal to a deviation in the period of a horizontal sync signal and the non-delayed composite video signal are selected in response to an H-period compensating signal, thereby producing a compensated color TV signal.
