摘要： 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. If multi-screen print is carried out on the 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.

摘要： 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. The primary derived functions of the first and second monotonous increasing non-linear functions are upwards convex, the domains of definition of input values thereof are consistent with the respective ranges of mapping values, and only one input value other than the limits in each domain of definition is equal to its mapping value. The only one input value and the mapping value are the central neighborhood values of the domain of definition and the range, respectively.

摘要： 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.
