  • Patent number: 9131225
    Abstract: A video display apparatus can adjust the parallax level of stereoscopic video images in accordance with the video image size and allows a user to make further parallax adjustment. The video display apparatus acquires the video image size of the stereoscopic video images, sets a default value of a depth adjustment value for adjusting the parallax level of the stereoscopic video images based on the acquired video image size, changes the depth adjustment value when the user has provided an input representing a change in the depth adjustment value, sets a parallax adjustment level of the stereoscopic video images based on the changed depth adjustment value, and adjusts the parallax level of the stereoscopic video images based on the parallax adjustment level.

  • Publication number: 20130229501
    Abstract: A video display apparatus includes a display section that carries out a display process based on a drive signal and a drive section that outputs to the display section a first drive signal based on a video signal having undergone video processing in a first video processing section at a fixed cycle and a second drive signal based on a video signal having undergone video processing in a second video processing section at the same cycle as the cycle at which the first drive signal is outputted but at timing shifted from the first drive signal by one-half the cycle. When the video signals contain two-dimensional video images, the first video processing section produces a video signal for two-dimensional video images and the second video processing section produces a video signal for black screen insertion.

  • Patent number: 7347564
    Abstract: The projector comprises an image forming panel that forms an effective panel image for modulating the light into an image light in an image forming area of a panel surface, and an image capturing unit for capturing a specific projection area wherein the image light corresponding to a specific area in the image forming area is projected. The projector calculates one or more edges of the outside perimeter lines of the screen and of the specific projection area by detecting plural points in a captured image. Based on the detection results, a post-correction image forming area is calculated, and trapezoidal distortion is corrected by forming the effective panel image within the post-correction image forming area. When only three or less of the four edges of the outside perimeter lines of the screen are detected, the projector calculates the post-correction image forming area based on the position and slope of the detected edge within the captured image.

  • Patent number: 7252386
    Abstract: The method comprises the steps of: capturing an output image projected on an actual projection surface; outputting imaging information that includes brightness information having a correlation to a brightness; and correcting a distortion of the output image in relation to the input image according to the imaging information. The distortion correcting step comprises the steps of: providing the image projector with a correction image for using in compensation of the distortion of output image; and determining a peak position movement amount, and also distorting in advance the input image so as to compensate for the distortion. The correction image is configured such that an angle change amount of the peak position according to the peak position movement amount, seen from the image projector is closer to the angle of the slope than an all white pattern image.
