The device and the method of generating strictly the pixel value of the pixel in the picture in order to generate the specimen point making use of decisive theory method

摘要

(57) Abstract The computer graphics device, the becoming dim with the movement vis-a-vis the scene which illuminates by the illuminant which has, the limited extent of the disk and the like (1) unlike the point light source, it occurs the soft shadow, (2) simulation of depth of field, (3), (4) jitter, including, pixel value of the pixel in the picture of the object in the scene is generated the series whose mismatch is small, for example making use of hole ton series as a specimen point in order to calculate integral calculus which is used in order to simulate several computer graphics technologies, strictly decisive theory. The computer graphics device generates the specimen point over the limited territory of the illuminant which has illuminated the scene making use of the series whose mismatch is small, (1) pertaining to the soft shadow, (2) pertaining to the simulation of depth of field, generates the specimen point over the territory of the lens with the scene and the picture, (3) pertaining to the becoming dim with the movement, generates the specimen point over the temporal interval which should simulate the blurring of the movement vis-a-vis the object where the inside of the scene is moving, at the same time, (4) pertaining to jitter, over the pixel which the picture or plural adjoins, jitter the specimen point which is doneIt occurs. Because the series whose mismatch is small unlike the random number which is used pertaining to the Monte Carlo analysis, guarantees that the specimen point is distributed evenly over the respective territory or temporal interval, error in the picture which has the fact that it occurs as a result of the thing where that kind of specimen point which has the fact that it occurs with the Monte Carlo analysis becomes firm is decreased. Especially as for this invention, when at the same calculation cost as those in the Monte Carlo analysis, using the specimen point of the same number, occurrence of the picture where picture quality improves is made easy.
