Abstract

The purpose of this study was to investigate the problems concerning how the color condition of a moving visual object and its background will influence the value of the timing error. The results obtaind were as follows: 1) In case that either an object or its background is colored and that the velocity of the object is as slow as 1m/sec, the value of the timing error was small under the condition of the longer wave length and higher chroma. When the velocity of the object was as fast as 7m/sec, the value of the timing error was small under the condition of the high brightness contrast which could be recognized even in comparatively fast speed among the several contrast conditions between the object and its background. 2) In case that the object and its background were in an achromatic condition, that is a moving object was white, while its background was black, gray or white, the timing error increased as the brightness contrast between them became greater, particularly under the condition of the fast velocity of the object. 3) In case that both the visual object and its background were colored with the visual object's velocity of 1m/sec, the small timing error was obtained especially under the condition that the wave length of the visual object was opposite to that of its background, namely, long vs. short or short vs. long. In the case of as fast speed as 7m/sec the small timing error was obtained under the condition of the short wave length of the background regardless of the length of the visual object.
