Traditionally, the conventional analysis of continuous dynamic images in terms of the cineradiographic images lacks objective criterion so that the quality analysis and comparison of the continuous images can hardly be seen. Therefore, some attempt was made to qualify the data using the visual experiment, especially in this study, focusing on the discriminative ability for the contrast of the images in the cineradiographic images, i.e. signal detection ability in the complex of the noises. Through the series of this study, our observed results indicted that 1) the contrast of the image is affected by the observation time of the series of the cineradiographic images, 2) the critical and threshold point measurement which were derived from the relationship between the time and contrast supplies the possible objective qualification and comparison among the series of the cineradiographic images, and 3) viewing the continuous dynamic images is superior to observing one frame static image with respect to the discriminative ability of the contrast.
