摘要

A video-image selection unit cyclically acquires at least two types of video images. A replacing mask determination unit selects, for each acquired video image, a mask pattern for masking a video image acquired by the video-image selection unit by replacing some pixels composing the video image with pixels of a single color such that said some pixels are spatially removed. Based on the mask pattern, the video-image replacing unit replaces said some pixels composing the video image with the pixels of a single color. A video-image output unit outputs the video image for which the replacement was performed. When selecting a mask pattern, the replacing mask determination unit selects a mask pattern that is different from a mask pattern used for the last video image, the mask pattern being different in the position of pixels not to be replaced with pixels of a single color.

1. An information processing method comprising:
making a video-image selection for cyclically acquiring at least two types of video images; making a mask determination for selecting, for each acquired video image, a mask pattern for masking the acquired video image by replacing some pixels composing the acquired video image with pixels of a single color such that said some pixels are spatially removed; and displaying on a display unit the video image after replacing said some pixels composing the video image with pixels of a single color based on the selected mask pattern, wherein, in the mask determination, when selecting a mask pattern for a certain video image, a mask pattern is selected that is different from a mask pattern used for the last video image, the mask pattern being different in the position of pixels not to be replaced with pixels of a single color, wherein in the mask determination, a mask pattern is determined based on the resolution of the acquired video image, and wherein in the mask determination, if the resolution of the acquired video image in the vertical direction is higher than that in the horizontal direction, a mask pattern that has a periodicity in the vertical direction of the video image is selected, and if the resolution of the acquired video image in the vertical direction is lower than that in the horizontal direction, a mask pattern that has a periodicity in the horizontal direction of the video image is selected.
