摘要： The gradation correction of input video signals is conducted in the gradation correctors based on lookup table data. The cumulative histograms of the input video signals are generated in cumulative histogram generators to set highlight points and shadow points. Based on the highlight and shadow points, the standard lookup table data stored in the standard lookup table storage is converted in lookup table data associated with the input video signals and outputted to gradation correctors. According to this method, an appropriate gradation correction can be achieved depending on the input video signals. The standard lookup table storage need only be loaded with the standard lookup table data, namely, a great volume of lookup table data need not be stored.

摘要： Tone correction for input video signals is performed on the basis of look-up table data. The state of color tone is decided by using chroma signals each corresponding to one of input video signals, and a luminance signal produced from the input video signals. In response to the particular state decided, signals are produced by applying color correction level adjustment to the input video signals. A highlight point and a shadow point are set up based on one of such adjusted signals so as to produce look-up table data for each of the input video signals. This allows input video data to be subjected to tone correction which corresponds to particular photographing conditions, thereby eliminating overcorrection or undercorrection. Hence, the operator's decision as to the state of color tone is needless so that the ease of operation is promoted.

摘要： Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered.

摘要： A holding stand is constituted by a carrying case for holding sheets of electronic paper and a base for uprightly supporting the carrying case that is substantially vertical. From the holding stand, two page fields, each expressing the number of pages of sheets of electronic paper to be displayed and position page field expressing a current page position of electronic paper and incremented on each of the sheets, are added to image data, and the image data is output to the sheets of electronic paper. In each sheets, when the two page fields coincide with each other in comparison between the two page fields, an image based on the image data is displayed in a display region. When the two page fields are different from each other, the position page field is incremented by one, and the position page field is transmitted to the next electronic paper.

摘要： To fill the ink cartridge with the ink, a first air introduction hole of a negative pressure generator chamber is sealed up, and a pressure pump is connected to a second air introduction hole of a storage chamber, to raise pressure inside the storage chamber so as to exhaust air out of an ink bag. While keeping the storage chamber under the high pressure, the second air introduction hole is sealed up, the first air introduction hole is opened, and an ink filling pump is activated to inject the ink through an ink outlet into the negative pressure generator chamber. When a predetermined amount of ink is injected, the second air introduction hole is opened, and the ink filling pump is reactivated to fill up the ink bag as well as the negative pressure generator chamber with the ink.

摘要： An ink cartridge, which is removably set in a printer, has an ink chamber storing ink, an absorbent chamber containing a sponge that absorbs the ink from the ink chamber and holds it, and a fuel chamber storing a liquid fuel to be supplied to a fuel cell of the printer. The fuel chamber is located outside and adjacent to the ink chamber, so that the ink stored in the ink chamber is kept in a constant temperature range. Data on residual amounts of the ink and the fuel in the ink cartridge are detected by a residual ink detector and a residual fuel detector of the printer, and are written in a memory card that is removably attached to the ink cartridge.

摘要： An image output system processes an input image signal from an image signal source, such as a television camera, to produce an output image signal to record an image on an image recording medium. The input image signal is logarithmically converted into an image signal which matches the image output system, using a first look-up table which is selected to match the image signal source. Then, the image signal, which has been converted by the first look-up table, is linearly converted into an image signal based on first corrective parameters set to achieve given color qualities. The image signal, which has been linearly converted, is converted an image signal which matches the image recording medium, using a second look-up table which is selected to match the image recording medium. The image signal, which has been converted by the second look-up table, is exponentially converted into an exponential output image signal based on second corrective parameters set to achieve given color qualities.
