ABSTRACT:
In a video display terminal (VDT) adapter connected to a moving picture output device, inputting means inputs, from the moving picture output device, an input moving picture signal indicative of input moving pictures having brightness which changes drastically. Connected to the inputting means, picture temporal frequency attenuator means selectively attenuates a particular frequency band of the input moving picture signal to produce a smoothly-changing moving picture signal indicative of smoothly-changing moving pictures. The particular frequency band includes human sensitive frequency components. Connected to the picture temporal frequency attenuator means, outputting means outputs the smoothly-changing moving picture signal as an output moving picture signal. The particular frequency band may lie on a range not less than 7 Hz.
