  • Patent number: 10088364
    Abstract: The invention relates to a method for two-dimensional, spatially resolved measurement of tristimulus values of light emitted from a plurality of positions on a sample. It is an object of the invention to provide an improved method and system for spatially resolved chromaticity and luminance measurement in a standardized color space for display testing. The method of the invention comprises the steps of: directing a first portion of the light to an RGB camera which produces a two-dimensional map of RGB color values; transforming the RGB color values into first tristimulus values to produce a map of tristimulus values; directing a second portion of the light to a colorimeter which produces second tristimulus values; deriving a tristimulus correction by comparing the second tristimulus values with at least a subset of the first tristimulus values; and applying the tristimulus correction to the first tristimulus values to produce a corrected map of tristimulus values.

  • Patent number: 8123117
    Abstract: In a proximity card function content distribution system of the invention, an IP-side apparatus 5 adds identification information of a user to simplified data of contents for the proximity card function, a mobile terminal 1A acquires the simplified data from the IP-side apparatus 5, and distributes the simplified data to another mobile terminal 1B, and when the another mobile terminal 1B performs proximity card communication with a R/W of the IP-side apparatus 5, the another mobile terminal 1B checks whether the terminal 1B has the specific simplified data, and communicates the checking information.

  • Publication number: 20070087785
    Abstract: A mobile terminal device and receiver sensitivity informing method for suitably receiving an electromagnetic wave from an external reader/writer to enable a user to use service promptly and reliably. In a mobile terminal device 1 that performs communication with an external R/W 2 in a noncontact matter, when an IC card section 12 receives an electromagnetic wave from the external R/W 2, a control section 11 determines a receiver sensitivity of the device 1 corresponding to the electromagnetic wave, and an informing section 14 informs the user of a different item of content corresponding to the determined receiver sensitivity of the device 1. The informing section 14 informs the user of the content using a display 141, vibrating device 142, speaker 143, emitting device 144 or a combination thereof.
