Abstract
An improved method for display of a transitional region of interest while transitioning between a first region of interest and a second region of interest within visual information on a display screen of a computer. The method comprising the steps of applying a transitional transformation to the visual information and displaying the transitional transformed visual information on the display screen. The transitional transformation requiring a reduced calculation for transforming the visual information in the transitional region.
Claims38
A method for generating a presentation of a region of interest in an original image for display on a display screen, comprising:
- applying a lens to a border region of the region of interest in the original image by displacing the border region onto the lens and projecting the displacing onto a plane in a uniform direction aligned with a viewpoint, wherein at least one of the lens and the viewpoint remain constant while transitioning between first and second locations for the region of interest in the original image.
A system for generating a presentation of a region of interest in an original image for display on a display screen, comprising:
- a processor coupled to memory and the display screen;
- and, modules within the memory and executed by the processor, the modules including:
- a module for applying a lens to a border region of the region of interest in the original image by displacing the border region onto the lens and projecting the displacing onto a plane in a uniform direction aligned with a viewpoint, wherein at least one of the lens and the viewpoint remain constant while transitioning between first and second locations for the region of interest in the original image.
A system for displaying a region of interest while transitioning between first and second locations for the region of interest within visual information on a display screen, comprising:
- a processor coupled to memory and the display screen;
- and, modules within the memory and executed by the processor, the modules including:
- a module for applying a transformation to a border region of the region of interest in the visual information to improve visual detail in the border region of the region of interest by:
- establishing a lens surface for the border region having a lens surface shape;
- and, generating a presentation by overlaying the visual information on the lens surface and projecting the lens surface with the visual information onto a plane in a uniform direction aligned with a viewpoint, wherein at least one of the lens surface shape and the viewpoint remain constant during the transitioning between the first and second locations;
- and,
- a module for displaying the presentation on the display screen.
