  • Publication number: 20180077321
    Abstract: An image processing apparatus includes an extraction unit, a memory controller, and a transfer unit. The extraction unit extracts, on the basis of image information, pieces of color information having a high frequency of occurrence as color information that is necessary to perform image processing. The memory controller causes a first memory to store a color information group including the pieces of color information extracted by the extraction unit. The transfer unit transfers the color information group from the first memory to a second memory, an access time of the second memory being shorter than an access time of the first memory.

  • Publication number: 20170219260
    Abstract: The purpose of the present invention is to achieve stable operation when using a low pressure, low GWP refrigerant. In the present invention, a control device (16) is provided with an estimation unit (31), a determination unit (32), and an activation control unit (33). The estimation unit (31) estimates the amount of air entering using a degree of influence of air entering, which represents the ease with which air enters determined by the structure of the chiller, and a variable obtained by a function including pressure as a parameter. The determination unit (32) determines whether a total value for the amount of air entering is greater than or equal to a preset tolerance value. The activation control unit (33) activates a bleed device when the total value of the amount of air entering is equal to or greater than the tolerance value.

    Abstract: A technique which comprehensively optimize passengers' convenience and a power consumption amount. An operation schedule evaluation apparatus has a passenger flow calculator and a power consumption amount calculator. The passenger flow calculator creates passenger flow information related to a passenger flow generated by transportation of a train, based on operation schedule information of each train and passenger information related to an entry and an exit of a passenger at a station. The power consumption amount calculator calculates the number of passengers or a car occupancy of each train based on the passenger flow information created by the passenger flow calculator, the operation schedule information and car information of each train, and calculates a power consumption amount of each train per unit time which reflects car weight corresponding to the number of passengers or the car occupancy.
