  • Patent number: 8218176
    Abstract: A communication device is configured to transmit subject data to be transmitted. A desired destination is designated by designating a desired abbreviated number contained in a facsimile number list which contains abbreviated numbers and respectively corresponding facsimile numbers. A predetermined operation is applied to a facsimile number corresponding to the desired abbreviated number to obtain a first operated value. Then, the desired abbreviated number and the first operated value are stored. The predetermined operation is applied again to a facsimile number corresponding to the desired abbreviated number as stored to obtain a second operated value after the transmission instruction is acquired. Whether the second operated value coincides with the second operated value is judged, and transmission of the subject data is aborted if the first operated value does not coincide with the second operated value.

  • Patent number: 5986767
    Abstract: A calorimetric apparatus includes an image pickup unit, an optical unit, a plurality of optical bandpass filters, a switching unit, an arithmetic processing unit, and an optimum filter selection unit. The image pickup unit picks up the image of light from a target object. The optical unit allows the light from the target object to form an image on the image pickup unit. The plurality of optical bandpass filters are arranged between the target object and the image pickup unit and have pass bands different from each other. The switching unit switches the plurality of optical bandpass filters. The arithmetic processing unit performs arithmetic processing for colorimetry on the basis of the spectrum data of the target object whose image is picked up. The optimum filter selection unit selects, from the plurality of optical bandpass filters, a filter suitable for colorimetry by the arithmetic processing unit.
