  • Patent number: 8334783
    Abstract: A projection display device includes: a dustproof filter that removes dust and a foreign material from drawn air; an air guide path that guides, to a liquid crystal panel, the cooling air blown by a suction fan; an air velocity detector that is arranged in the air guide path and detects the velocity of the cooling air that flows in the air guide path; and a CPU that determines, on the basis of the value detected by the air velocity detector, whether or not the dustproof filter is clogged. The air velocity detector detects the velocity of the cooling air by measuring the temperature of the air in the vicinity of the heat generating element that will be increased due to heat transfer generated by the heat generating element. This configuration improves accuracy in determining whether or not the dustproof filter is clogged.

  • Publication number: 20110075173
    Abstract: A group of spectral data of print mediums and a group of laminating film spectral data are stored, which correspond to a plurality of colors on a color chart. The type of print medium and the type of laminating film are entered. From the group of spectral data of print mediums and the group of laminating film spectral data, spectral data corresponding to the entered type of print medium are entered as first spectral data, and spectral data corresponding to the entered type of laminating film are entered as second spectral data. Colorimetric value data of the colors are calculated using the first spectral data and the second spectral data.

  • Publication number: 20110075172
    Abstract: An association table is generated which associates print information with color values. Print information of a print is encoded into target color values based on the generated association table. Image data of management patches having the target color values are added to image data for printing the print. The print, which is printed by a printing machine, is colorimetrically measured to acquire color values of the management patches. The acquired color values of the management patches are decoded into print information based on the association table. The association table is generated depending on a gamut of the printing machine.

  • Publication number: 20110069332
    Abstract: It is determined whether an entered designated color is a color within a gamut of a printing machine or not. If the designated color is judged as being not a color within the gamut, then the designated color is mapped to converted colors within the gamut according to a plurality of gamut mapping processes. One of the gamut mapping processes which corresponds to one of the converted colors is selected. If the designated color is judged as being a color within the gamut, the designated color is set as a reference color. If the designated color is judged as being not a color within the gamut, then the selected one of the converted colors is set as the reference color.

  • Publication number: 20110069333
    Abstract: Image data used for printing a designated color adjusting color chart having color patches with a printing machine are generated, color values and positions of the color patches being associated with each other. A patch selection image simulating the positions of the color patches on the color chart is displayed. Coordinates corresponding to the position of a color that has been selected as a color that is closest to the designated color from the color patches of the color chart, are indicated on the displayed patch selection image. Color values of the color that is closest to the designated color are calculated based on the color values and positions that are associated with each other and the indicated coordinates.

  • Patent number: 7701608
    Abstract: An automatic counting device for measuring the number of target objects included in an image, which includes a discrimination section, a counting section, and a correction section. The discrimination section discriminates the target objects included in the image based on face information extracted from the image. The counting section measures the number of target objects discriminated by the discrimination means. The correction section corrects the number of each type of target object measured by the counting section such that the counting error arising from the difference in the discrimination accuracy between each type of target object is minimized based on information related to the discrimination accuracy for each type of target object.
