Abstract: In a perimetry to be conducted, designating an inspection region through a region designator, stimuli are presented to regions separated in an up/down direction, an oblique direction and a right/left direction from the inspection region (“the spaced region”) in addition to the designated inspection region. At the result, examinees are not able to predict to which of both regions, the inspection region and the spaced region the stimuli are presented, thereby obtaining correct inspection results that do not receive a prediction of the examinees.

Abstract: A video image decoding device includes a processor that executes a process. The process includes extracting group information expressing a group from an input stream indicating encoded data of blocks obtained by dividing each picture included in video image data, calculating decode time information for each group, calculating an output time for each group; receiving the input stream, decoding the input stream, outputting decoded blocks, saving the decoded blocks, outputting the decoded blocks included in each group saved in a frame memory, and controlling display of each group. The decoding includes confirming whether all data used for decoding has arrived at the decode time of one group. The controlling includes controlling the outputting to display another decoded block saved in the frame memory instead of the decoded blocks included in the one group, when all data used for decoding hasn't arrived.

In such a configuration, an examinee knows the time to finish the inspection, and is able to highly keep his (her) concentration in comparison with a case where the required time is not known, thereby improving precision of the inspection.

Abstract: Through the present invention, a perimetry result is obtained for a position on a retina surface designated as a position to be tested. As illustrated in the drawing, “the position of a ganglion cell (RGC)” and “the position of a photoreceptor cell (C) for sending information to the ganglion cell (RGC)” are offset on the retina surface (macular part). Here, when position (P1) is designated as a test position for testing the functioning of a ganglion cell at position (P1), the perimeter of the present invention finds “the position (P2) of the photoreceptor cell for sending information to the ganglion cell at position (P1),” presents a visual target at position (P2) rather than position (P1), and tests a visual field. The information of the visual target is sent to the ganglion cell at position (P1), and the functioning of the ganglion cell can therefore be tested.

Abstract: A video encoding apparatus appends decoding delay and display delay correction information to encoded video data in order to ensure that even when one or more pictures that are later in encoding order than a starting encoded picture in a video data stream to be spliced to a trailing end of another encoded video data stream have been discarded from among pictures contained in the video data stream, the starting encoded picture and its subsequent pictures can be continuously decoded and displayed by a video decoding apparatus. The correction information is calculated based on a decoding interval between each discarded picture and a picture that immediately precedes the discarded picture. The video decoding apparatus corrects the decoding delay and display delay of the starting encoded picture and its subsequent pictures by using the calculated correction information.
