Information display processing device and control program for information display processing device

An operation-assisting device for assisting user operations related to a target software, comprising:

• a) an identification-header detection section for detecting a single identification header displayed on a screen of a display unit, the single identification header being in a predetermined positional relationship to a code image, and holding only information which enables locating the code image;
• b) a code-image detection section for detecting, based on the predetermined positional relationship with the identification header detected by the identification-header detection section, the code image in which a specified item of information related to the target software is held in a coded form;
• c) a decoding section for decoding the code image detected by the code-image detection section, to obtain the specified item of information;
• and
• d) an execution section for performing a specified process associated with the specified item of information obtained by the decoding section wherein the code image and the identification header are composed of a plurality of pixels having color differences which are difficult to be visually recognized by users;
• and wherein the display unit displays the code image and the identification header in a uniformly-colored area within a designated region occupied by a color close to the plurality of pixels.

An operation-assisting device for assisting user operations related to a target software, comprising:

• (i) an information display processing device for displaying a predetermined process result on a screen of a display unit, the information display processing device including:
• a) an encoding section for creating a code image by encoding a piece of information held in the device;
• and
• b) a display control section for displaying, on the screen, the code image created by the encoding section and a single identification header in a predetermined positional relationship to the code image,
• wherein the single identification header holds only information which enables locating the code image;
• wherein the code image and the identification header are composed of a plurality of pixels having color differences which are difficult to be visually recognized by users;
• and
• wherein the display control section displays the code image and the identification header in a uniformly-colored area within a designated region occupied by a color close to the plurality of pixels;
• (ii) an identification-header detection section for detecting a single identification header displayed on a screen of a display unit, the single identification header being in a predetermined positional relationship to a code image, and only holding information which enables locating the code image;
• (iii) a code-image detection section for detecting, based on the predetermined positional relationship with the identification header detected by the identification-header detection section, the code image in which a specified item of information related to the target software is held in a coded form;
• (iv) a decoding section for decoding the code image detected by the code-image detection section, to obtain the specified item of information;
• and
• (v) an execution section for performing a specified process associated with the specified item of information obtained by the decoding section,
• wherein the identification-header detection section is configured so that, for a natural number N equal to or greater than three, the identification-header detection section searches the screen in the row direction, examining a value of each pixel, and if a pixel whose color differs from a preceding pixel is detected, the identification-header detection section determines whether or not the detected pixel is a pixel in an N+1 st column of the identification header, and if a determination result is negative, the identification-header detection section resumes the search from a pixel which is N columns far ahead of the detected pixel.
