Abstract: A image providing device provides a user with realistic and natural past-experience simulation through stereoscopic photographs. Specifically, feature-point extractors extract feature points from a foreground image and a background image, respectively. A stereoscopic matching module searches for pairs of feature points matching between the foreground image and the background image and obtains using the feature point pairs a transformation matrix for projecting the foreground image onto the background image. The transformation by the transformation matrix obtained by the matching unit is applied to foreground depth data, which is depth data of the foreground image. Lastly, depth based rendering is performed based on the transformed foreground depth data to obtain two or more viewpoint images corresponding to the foreground image.

Abstract: A image providing device provides a user with realistic and natural past-experience simulation through stereoscopic photographs. Specifically, feature-point extractors 15 and 22 extract feature points from a foreground image and a background image, respectively. A stereoscopic matching module 25 searches for pairs of feature points matching between the foreground image and the background image and obtains using the feature point pairs a transformation matrix for projecting the foreground image onto the background image. The transformation by the transformation matrix obtained by the matching unit is applied to foreground depth data, which is depth data of the foreground image. Lastly, depth based rendering is performed based on the transformed foreground depth data to obtain two or more viewpoint images corresponding to the foreground image.

Abstract: A processor detects a function which includes no function call instruction and no update of the return address /calculation register from an assembler program. After the detection, the processor outputs a special return address to the end of the function detected, and executes the assembler program. The processor stores a return address not only on the stack but in the return address/calculation register. When the special return instruction has been fetched, the return address is moved from the return address/calculation register without accessing to the stack.

Abstract: A resource assignment apparatus for use with a software compiler or translator for compiling or translating a high-level source program into a machine language program, wherein the resource assignment apparatus assigns the variables in the high-level source program to system resources consisting of registers, memory, and the like. The resource assignment apparatus generates assignments consisting of the variables and their live ranges and finds the interference cost incurred when assigning these various assignments to each of the various resources, consisting of data registers, address registers, memory, and the like. The apparatus sorts the assignments into groups whereby these interference costs will be the lowest. The resource element minority assignment unit then carries out the assigning of each of these groups of sorted assignment. The various assignments with live ranges which interfere are assigned to different resource elements.
