A method and apparatus for displaying an image that is subject to multiple distortions substantially without distortion is provided. The image is recorded from a first viewpoint and subject to a first distortion and played back from a second viewpoint and subject to a second distortion. The display surface may also be distorted (e.g., curved). By mapping back through the projector to the screen and through the camera (at the viewpoint), the image is transformed so that it can be viewed from the viewpoint with little or no distortion.
An imaging apparatus includes an objective lens system for forming an image of an object, a solid-state image pickup device, a signal processor and a display device. The objective lens system includes at least one revolutionally asymmetrical refractive surface for deforming the image formed by the objective lens system and is configured so as to deform further the image which is deformed by the signal processor.
In a signal processing circuit used for displaying an image on a two-dimensional display element, an inverse-distorted image creator is provided which previously distorts the image to be displayed on the two dimensional display element so as to have a characteristic inverse to the distortion generated in the eyepiece optical system. The inverse-distortion correction is made for each of the image signals of the three primary colors R, G and B.
A method is for inverting a distorted surface presentation into an undistorted surface presentation in a detail-in-context presentation system including the steps of: selecting an input point on the undistorted surface; calculating a vector from the input point to a reference viewpoint; locating a starting point lying above the distorted surface and on the vector; locating a first bracketing point for a first intersection point of the vector and the distorted surface lying above the distorted surface and on the vector; locating a second bracketing point for the first intersection point lying below the distorted surface, and below the first intersection point, but above any subsequent intersection points of the vector and the distorted surface; locating a midpoint between the first and second bracketing points; and, determining if the midpoint is an acceptable approximation for the first intersection point thus being an inversion point corresponding to the input point.
An endoscopic viewing system for maintaining a surgeon's normal sense of kinesthesia during endoscopic surgery regardless of the orientation of the endoscope vis-a-vis the surgeon.
The present invention relates to a video system for entertainment and game apparatus. The video system includes a data carrier on which the game is stored. Video informations (pictures) stored on the data carrier are displayed on a display unit. By a lens and projection system the picture is imaged on a curved projection screen that at least partially surrounds the player. Preferably, the video informations are stored on the data carrier in pre-equalized form so that the image projected on the projection screen is essentially free of distortion.
