Abstract: A display device includes a display in which an image is displayed; an output controller configured to display an image in the display; an imager configured to capture an image of an object present within a field of view of a user; a visually recognized object identifying unit configured to identify, based on the captured image, a type of the object present within the field of view of the user; and a visual recognition count identifying unit configured to, based on an identification result by the visually recognized object identifying unit, identify a visual recognition count indicating a number of times by which the user has looked at the object for each of the identified type, wherein the output controller is further configured to display in the display, based on the visual recognition count, a sub image including information on the object for each of the identified type.

Abstract: An information providing device includes a display unit configured to output a visual stimulus; a sound output unit configured to output an auditory stimulus; a sensory stimulus output unit configured to output a sensory stimulus; an environment sensor configured to detect position information of the information providing device; a biological sensor configured to detect cerebral activation degree of a user; an output selecting unit configured to select, based on the environment information, one of the display unit, the sound output unit, and the sensory stimulus output unit; an output specification deciding unit configured to decide on a reference output specification for adjusting outputs of the display unit, the sound output unit, and the sensory stimulus output unit, based on the position information; and a user state identifying unit configured to calculate an output specification correction degree for correcting the reference output specification, based on the cerebral activation degree.

Abstract: An input two-dimensional image is divided into equal-size blocks. MIP maps with different resolutions are generated in response to each of the blocks. A memory stores data representative of the MIP maps for each of the blocks. Polygon data represent conditions of a polygon and also a correspondence between the polygon and positions of pixels of a two-dimensional image to be applied to the polygon. On the basis of the polygon data, at least one is selected from the MIP maps represented by the data in the memory as a desired MIP map on a pixel-by-pixel basis. Data representative of the desired MIP map are read from the memory. Calculation is made as to a color intensity of each pixel in a final image in which the desired MIP map is applied to the polygon on a pixel-by-pixel basis. Data representative of each calculated pixel color intensity are outputted.

Abstract: Original data is reconstructed from an MPEG (Moving Picture Experts Group) bitstream including at least one elementary layer bitstream. The elementary layer bitstream is made of an upper layer bitstream and a plurality of lower layer bitstreams that follow the upper layer bitstream. A start code added to a header of the MPEG bitstream is detected to generate a start code detection signal. Control packets are generated when it is judged, in response to the detection signal, that the detected start code is added to the header of the upper layer bitstream. The control packets carry information on reconstruction of the original data that has been coded into the lower layer bitstreams. The lower layer bitstreams are processed according to the control packets to reconstruct the original data. The start code judgement and the control packet generation are achieved by software. On the other hand, the lower layer bitstream processing is achieved by wired-logic circuitry.

Abstract: A jagged-edge killer circuit for a three-dimensional display, comprises a frame buffer for storing data of each pixel on the display screen by a pixel unit; a Z-buffer for storing distance data in a depth direction of a picture by a sub-pixel unit into which the pixel as a storage unit of the frame buffer is subdivided in a predetermined number; a picture data buffer for storing picture data by the sub-pixel unit; an element for comparing the distance data stored in the Z-buffer with new distance data in the depth direction about each new sub-pixel into which new pixel is subdivided in the predetermined number when picture data of said new pixel are written in the picture data buffer; a first element for renewing storage contents of the picture data buffer about only sub-pixel having nearer distance in the depth direction within the sub-pixels subdivided from the new pixel into the predetermined number on the basis of a comparison result of the comparing element; a second element for renewing storage contents
