Abstract: In order to avoid a load change which occurs when seam O passes by the heads affect image information, a dyeing layer transfer head and recording heads are located in equal intervals having length P, which is obtained by equally dividing an entire circumference K of a recording intermediate belt by n (n is integer), and, given that the position of the seam of the recording intermediate belt, which does not have an end obtained by coupling two ends of a belt body of a band shape, is origin O, images are formed in portions except for portions at origin O, or at a distance of 1×P, 2×P, . . . (n?1)×P from origin O. In this way, it is possible to prevent deterioration in the image quality, such as a stripe line in an image formed by an image forming apparatus.

Abstract: When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. If multi-screen print is carried out on a printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

Abstract: When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. By turning on a reproduction switch, a picture file is read out from the nonvolatile memory means, the compressed data is expanded and converted to an analog signal, and the converted picture is displayed on a liquid crystal display. By pressing a display feed key, another picture file is read out and displayed. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. The nonvolatile memory means can be removed. By mounting this memory means on a printer unit, display unit or picture transmission unit, the digital camera also can be used during print, display or transmission of the picture.

Abstract: An image forming apparatus is provided, which comprises a dye transfer section for transferring a dye of a dye transferring member onto an outer surface of a circularly moving recording intermediate belt, wherein the dye transferring member comprises a base material and the dye is provided on the base material; and a recording paper transfer section for transferring the dye transferred onto the recording intermediate belt onto recording paper. In a dye transfer operation state, the second roller draws out the dye transferring member and the dye on the drawn dye transferring member is transferred onto the recording intermediate belt facing the dye transferring member. When the dye transfer operation state is changed to a standby state, the first roller winds back the dye transferring member so that a portion of the dye transferring member from which the dye has been transferred faces the recording intermediate belt.

Abstract: An apparatus for printing video images is disclosed. First the percentage of backlighting or people in the image is detected. That is, the probability of the presence of backlighting or people is detected. Then, the density gradation table is modified based on the detection result, and the presence of backlighting or the presence of people in the image is evaluated based on optical information, to select the best density gradation table from among plural density gradation tables, or to synthesize the best density gradation table. A luminance table is generated using the optimized density gradation table, and gradation correction of the image is then accomplished using that luminance table.

Abstract: In an image data including tone information, a level of an attentional picture element in an image and a level of an adjacent picture element located adjacent to the attentional picture element are smoothed to create a first substitution level, and by internally dividing the level of the attentional picture element and the first substitution level with a predetermined internal division ratio to obtain a second substitution level which finally substitutes the level of the attentional picture element.

Abstract: The present invention discloses a missing pixels interpolating method and an apparatus using the method. The method forms a second image from a first image by interpolating a plurality of pixels constituting the first image with a plurality of first pseudo-pixels in such a way that they neighbor to the pixels diagonally and with a plurality of second pseudo-pixels in such a way that they neighbor to the pixels vertically and horizontally. The method comprises the first process of computing values of the first pseudo-pixels using a first monotonous increasing non-linear function, and the second process of computing values of the second pseudo-pixels using a second monotonous increasing non-linear function.

Abstract: An image data processing apparatus for generating a font with contour lines expressed with gradations comprises a font ROM for storing a binary font data. An output port is provided for reading a target pixel with ambient pixels arranged in 3.times.3 matrix of the binary font data stored in the font ROM. A shift register produces an address data based on the binary data read from the font ROM. A look-up table has 2.sup.3.times.3 elements in which multilevel values in commensurate with the pixel patterns included the 3.times.3 matrix. One data of the multilevel data is output from the look-up table by designating one element by said address data, and is used as a gradation data of the target pixel. Thus, pixel of font can be expressed with a gradation, the jagged contour of the font is reduced.
