Abstract:
A depth of field rendering apparatus, method and program displays a sense of distance using a Z buffer to establish a depth direction of objects in an image and generating an image in a just-in-focus state while writing a Z value of each of dots in the image into the Z-buffer. A blurred image is produced from the just-in-focus image and portions of the blurred image are selectively overwritten on the just-in-focus image by comparing a preset Z value to the Z value of each of the data in the Z buffer.
Abstract:
An information perusal program arranges information within a virtual space, where the information is arranged in uniquely specified storage positions. The information perusal program detects a position specified arbitrarily by the user within the virtual space. The information perusal program then detects an arrangement position within the virtual space in an area having a virtual spread in relation to the specified position and acquires information from the storage position corresponding to the arrangement position. Accordingly, the user is able to easily peruse information whose storage position is uniquely specified, such as, for example, a site on the Internet, a local folder and/or file, and so forth without performing complex and complicated input operations in order to specify the storage position. In addition, it is possible to easily realize perusal information without a specific object.
