Abstract: A control apparatus 220 controls the in-focus positions of a plurality of image capturing apparatuses that perform image capturing from a plurality of directions in order to generate a virtual-viewpoint image. Specifically, the control apparatus 220 obtains an image capture parameter related to image capturing by one or more image capturing apparatuses included in an image capturing apparatus group 100. The control apparatus 220 controls on the basis of the obtained image capture parameter, the in-focus position of a target image capturing apparatus corresponding to the image capture parameter such that the distance from the target image capturing apparatus to the in-focus position of the target image capturing apparatus is shorter than the distance from the target image capturing apparatus to a point of interest.

Abstract: A cell type page which displays a fixed number of images at fixed positions with fixed size on a screen and a free type page which displays equal to or more than one image at arbitrary positions with arbitrary size on the screen are provided. In response to an image insertion order in the cell type page, images belong to the cell type pages behind that cell type page are sent astern without influencing positions of images belong to the free type pages behind that cell type image and blank pages are added if there is no blank cells. In response to an image deletion order from the cell type page, images behind an image to be deleted belong to the cell type pages behind that cell type page are closed ahead without influencing positions of images belong to the free type page behind that cell type page and the blank pages are deleted if the blank pages are appeared.

Abstract: A recording apparatus for recording moving image data on a disk-like recording medium detects a defective area on the disk-like recording medium, determines a continuous data area for the moving image data on the basis of a data rate of the moving image data to be recorded and the detected defective area, and records the moving image data in accordance with the continuous data area.

Abstract: A coated preparation for the detection of a H. pylori infection according to a urea breath test protocol which comprises a core composition containing at least an isotope C-labeled urea, an excipient and a lubricant in defined proportions and covered with 0.1˜10 weight % of a coating agent based on 100 weight % of the core composition. With this preparation, the influence of the urease-producing bacteria resident in organs other than the stomach, such as the mouth and throat, is excluded to enable a diagnosis of H. pylori infection without the risk for a false-positive test and with reasonable rapidity.

Abstract: Provided is an information recording/reproducing method and apparatus which can reduce the frequency of access to an information recording medium as much as possible and shorten reading/writing time. An application program or a file system driver has a means for setting a predetermined area in the cache buffer area to overwrite inhibited. Thus, when the data to be read out again is set to overwrite inhibition, the data is not deleted from the cache buffer. Therefore, access to the disk is not caused at the time of re-reading or re-writing, which can shorten reading/writing time.

Abstract: A cell type page which displays a fixed number of images at fixed positions with fixed size on a screen and a free type page which displays equal to or more than one image at arbitrary positions with arbitrary size on the screen are provided. In response to an image insertion order in the cell type page, images belong to the cell type pages behind that cell type page are sent astern without influencing positions of images belong to the free type pages behind that cell type image and blank pages are added if there is no blank cells. In response to an image deletion order from the cell type page, images behind an image to be deleted belong to the cell type pages behind that cell type page are closed ahead without influencing positions of images belong to the free type page behind that cell type page and the blank pages are deleted if the blank pages are appeared.

Abstract: An operation of a recording/reproducing portion is controlled by a control portion so as to record data in a predetermined recording region on a recording medium, and perform update recording in the predetermined recording region in accordance with occurrence of update information of the data. The control portion further has a function of controlling the recording/reproducing portion so as to record an update portion of data in a temporary storage region in a part of the recording medium and record an update flag showing whether the predetermined recording region has been updated with the update portion or has not been updated with the update portion in an update flag region, and in update recording with respect to the predetermined recording medium, successively performs operations of recording the update portion in the temporary storage region, setting the update flag in a non-updated state, recording the update portion in the predetermined recording region, and setting the update flag in an updated state.

Abstract: In response to a request for deletion of intermediate portion of moving picture data stored on a random-accessible storage medium, data corresponding to the request is substantially deleted, and the portion corresponding to the deletion request is excluded from the subject of reproduction in precise frame units. When a request for deletion of intermediate portion of moving picture stream data has been made, the data from a GOP immediately after a deletion start position to a GOP immediately before a deletion end position is deleted. Then a play list is generated to exclude frames from the deletion start position in a GOP designated with the deletion start position and frames before the deletion end position in a GOP designated with the deletion end position from the subject of reproduction.
