The image display device includes an input unit that receives image data, a display unit that displays the image data received by the input unit, a receiving unit that receives drawing data drawn on the image data displayed on the display unit, an output unit that outputs the image data to another device, and a computing unit. The computing unit performs specific image adjustment on the image data, and causes the display unit to display the image data without performing the specific image adjustment on the image data when the specific image adjustment has been performed on the image data received by the input unit.

In a semiconductor integrated circuit, one of two signals generated from a first logic circuit is delayed in a first delay addition circuit, looped back by an input/output terminal, and then inputted to a second logic circuit. The other output of the first logic circuit is looped back by a reference input/output terminal, further delayed in a second delay addition circuit, and then inputted to the second logic circuit. By varying respective amounts of delay added by the first and second delay addition circuits from each other, AC timing specifications are satisfied and it is determined whether or not the semiconductor integrated circuit has passed a test based on whether or not the output of the second logic circuits is a desired signal relative to the input of the first logic circuit.
