Claim Text:
1. A display device, comprising: a display unit configured to display images each corresponding to a respective one of a plurality of shutter mechanisms that carry out opening and closing operation at timings different from each other, in such a manner as to switch the images in a time-division manner; and a shutter controller configured to set a respective one of the shutter mechanisms to an opened state in a display period of the image corresponding to the respective one of the shutter mechanisms, and variably control at least one of start time and length of an opened-state period of the shutter mechanism, wherein the plurality of images are a left-eye image and a right-eye image having parallax, further comprising a video processor configured to detect at least one of an amount of parallax and contrast between the left-eye image and the right-eye image, wherein the shutter controller sets at least one of the start time and length of the opened-state period based on at least one of the amount of parallax and the contrast, the display unit performs displaying by writing a video signal while line-sequentially scanning a display screen, the video processor detects a profile of the amount of parallax along direction of the scanning, the shutter controller changes the start time depending on the profile of the amount of parallax, and the shutter controller changes the start time set based on a first position on the screen to a time earlier than a previous start time if a position at which the amount of parallax is largest is closer to a scanning start position than the first position, and changes the start time to a time later than the previous start time if the position at which the amount of parallax is largest is closer to a scanning end position than the first position.
