Abstract: A reading processing apparatus for a temperature display device includes: an obtaining device obtaining an image of the temperature display device; a storage storing color fading information for each temperature; and a temperature estimation device estimating an ambient temperature of the temperature display device. The obtaining device includes a time information image indicating time information and a temperature information image displaying information about a temperature and an elapsed time by a change in color, and to which image pickup time information is added. The color fading information indicates a relation between a color changed by a temperature change, an elapsed time, and a temperature. The temperature estimating unit estimates the temperature to which the temperature display device is exposed by checking color information and elapsed time detected from the image against the color fading information stored in the storage.

Abstract: To print a code to be read by a machine as well as information to be read by a user on a limited print surface with efficiency. An ID pattern is defined in a frequency domain and is transformed through an inverse Fourier transform. As a result of the inverse Fourier transform, the ID pattern becomes a pattern (ID background image) dispersed across a screen. In the printing apparatus according to the present invention, the ID background image is set as a background image, on which human-readable information composed of characters, images (designs), and/or the like are printed. Even thought the ID background image is lost, in a portion in which the human-readable information printed, it is possible to restore the ID pattern by Fourier-transforming the pattern in a remaining portion of the ID background image.
