  • Publication number: 20120056895
    Abstract: The present invention provides an image processing device, a color correction table generation device, a display device, an image processing method, a color correction table generation method, a color adjustment method of a display device, and an image processing program capable of color matching to preferred colors of which excessive emphasis in chroma is suppressed. There are provided a chroma limit setting section for setting a chroma limit based on a optimal color, and a color correction table generation section for generating a color correction table by making a correspondence between an input color and an output color having chroma no greater than a chroma limit. The color correction table is stored in a color correction table storage section. The color correction execution section executes color correction along the color correction table so that the projector outputs a color with chroma no greater than the chroma limit.

  • Publication number: 20080259369
    Abstract: The present invention has an object of providing an image processing device, a color correction table generation device, a display device, an image processing method, a color correction table generation method, a color adjustment method of a display device, and an image processing program capable of color matching to preferable colors of which the excessive emphasis in chromaticness is suppressed. [Means for Resolution] There are provided a chromaticness limit setting section 203 for setting a chromaticness limit based on a brightest color, and a first color correction table generation section 204 for generating a first color correction table by making a correspondence between an input color and an output color having chromaticness no greater than a chromaticness limit and included in a color reproduction area of the projector 1. The first color correction table generation section 204 stores the first color correction table thus generated in a first color correction table storage section 211.

  • Patent number: 6637218
    Abstract: The present invention provides a gas heat pump-type air conditioner that can reliably notify a user that the time for changing the engine oil of the gas engine that drives the compressor has arrived without stopping the operation of the gas engine. In a gas heat pump-type air conditioner that forms a cooling cycle by circulating refrigerant using a compressor having a gas engine as a drive source, when the cumulative hours of operation t of the gas engine reaches a second predetermined time T2 (S3), a warning display A is displayed while the operation of the gas engine continues, and thereby the user is notified that the time for changing the engine oil has arrived (S4), and at the same time, after the initial stop procedure is carried out subsequent to reaching the predetermined time T2 (S5), a warning display B is displayed (S6), and the warning restoration operation procedure (S7) is carried out.
