Adjusting apparatus, method, and recording medium, and abnormality display apparatus, method, and recording medium

An abnormality display method for displaying an abnormality in a display apparatus, the display apparatus being formed of a plurality of video display units arranged in a matrix and which combine to display an image based on an input video signal, each given one of the plurality of video display units displaying a respective portion of the image based on the position of that display unit in the matrix, the display apparatus having screen information supplying means for supplying screen information including at least position information indicating respective positions of each one of said plurality of individual video display units in the matrix for and/or layout information indicating a number of horizontal display units and a number of vertical display units forming the matrix, and abnormality signal generating means for generating an abnormality signal when the abnormality occurs in an individual one of the plurality of video display units, said abnormality display method comprising the steps of:

• displaying a pseudo screen window that concurrently and schematically represents all of the plurality of video display units that form the display apparatus as a corresponding plurality of pseudo display units, each given one of the plurality of pseudo display units being arranged in the pseudo screen window according to the position of its corresponding display unit in the matrix based on the screen information supplied by said screen information supplying means;
• generating the abnormality signal when the abnormality occurs in the individual video display unit;
• and
• distinguishably displaying, in said pseudo screen window, the particular one of the plurality of display units that corresponds to the individual video display unit having the abnormality based on the generated abnormality signal.

A recording medium storing a program having instructions for carrying out a method of displaying an abnormality in a display apparatus, the display apparatus being formed of a plurality of video display units arranged in a matrix and which combine to display an image based on an input video signal, each given one of the plurality of video display units displaying a respective portion of the image based on the portion of that display unit in the matrix, the display apparatus having screen information supplying means for supplying screen information including at least position information indicating respective positions of each one of said plurality of individual video display units in the matrix for and/or layout information indicating a number of horizontal display units and a number of vertical display units forming the matrix and abnormality signal generating means for generating an abnormality signal when the abnormality occurs in an individual one of the plurality of video display units, said method comprising:

• displaying a pseudo screen window that concurrently and schematically represents all of the plurality of video display units that form the display apparatus as a corresponding plurality of pseudo display units, each given one of the plurality of pseudo display units being arranged in the pseudo screen window according to the position of its corresponding display units in the matrix based on the screen information supplied by said screen information supplying means;
• generating the abnormality signal when the abnormality occurs in the individual video display unit;
• and distinguishably displaying, in said pseudo screen window, the particular one of the plurality of display units that corresponds to the individual video display unit having the abnormality based on the generated abnormality signal.
