Abstract
Method, system and computer program for visually highlighting identified failing or erroneous pixel elements of a two-dimensional electronic image. Different visual highlighting techniques are stored in memory. A user selects one of the highlighting techniques using a user interface. A processor applies the selected technique(s) to the image and displays the image on a display with visual indications of the failing pixel elements. The techniques include coloring the pixels with a boundary box enclosing all of the erroneous pixels, enclosing separate irregular-shaped groupings of the pixels with a contour-type boundary line, and coloring pixels and enclosing each within a separate box. In the final technique, video lines with some failing pixels, but within allowable tolerances, will have those pixels colored differently and each pixel is enclosed within the same color box. In all cases, it is possible to convert the test image to black and white for display.
