  • Patent number: 7668368
    Abstract: A correction processing section 1 performs a color correction such that a movement amount indicating how much input values of image signals should be moved for the purpose of color correction becomes smaller as the distance between the input values and the coordinates of the center of region to be corrected becomes larger in the region to be corrected, based on the input values of the input signals (L signal, *a signal, *b signal), conditional data (such as radius r) defining a local region to be corrected, the coordinates (Lc, *ac, *bc) of the center of the region to be corrected and the coordinates (Lm, *am, *bm) of the center of an ideal color region to be targeted.

  • Patent number: 7668473
    Abstract: There are provided a fixing device and an image forming apparatus capable of reducing a sensing error of a surface temperature of a heating roller. The fixing device includes a temperature sensor for sensing the surface temperature of the heating roller, and a temperature calculation circuit. The temperature calculation circuit includes a noise removal prevention circuit. The temperature sensor includes an infrared ray sensing thermistor and a compensation thermistor, and the noise removal prevention circuit prevents removal of a part of an AC component (such as a high frequency component in a noise) included in a difference between outputs (difference output) of the infrared ray sensing thermistor and the compensation thermistor. Thus, the AC component is prevented from being offset when the difference outputs are averaged, thus reducing the sensing error of the surface temperature of the heating roller based on the average value of the difference outputs.

  • Patent number: 7665104
    Abstract: In a conventional content transmission system, there has been a problem that it takes a long time from when a user, who tries to start viewing and listening of content, issues a command to a receiver by using a remote controller or the like until when the user can actually view and listen to the content from content viewing and listening equipment (content starting time). To this end, a content transmission system according to the present invention has a transmitter and a receiver including a human sensor and has a configuration that the state of the receiver is changed corresponding to a detection result of the human sensor so as to reduce the content starting time and power consumption.

  • Patent number: 7662288
    Abstract: In a water treatment system, micro-nano bubbles are used in a production device and a detoxification device as one example of the upstream treatment devices which perform specified treatment with use of water. The micro-nano bubbles are used again in the waste water treatment by a waste water pretreatment device and a waste water treatment device in the subsequent step. Since the micro-nano bubbles are reused, the efficiency of the micro-nano bubbles can be enhanced. Moreover, according to the waste water pretreatment device, treatment water is pretreated with the microorganisms activated by micro-nano bubbles and propagating in a polyvinylidene chloride filler material and then it is introduced into the waste water treatment device in the subsequent step. Thereby it is possible to reduce the waste water treatment load in the waste water treatment device in the subsequent step.
