Abstract: In a scene recognition photographing device of the present invention, a feature quantity of an acquired image acquired from an image pickup element is calculated from the acquired image. Plural types of reference feature information having a feature quantity serving as a reference at the time of determining a composition are stored as a database in an internal memory or a storage device. Moreover, a camera control unit retrieves reference feature information having a feature quantity similar to the feature quantity of the acquired image from among the reference feature information by comparing the calculated feature quantity and the reference feature information. Then, information relating to composition is displayed on a display device on the basis of a result of comparison between the acquired image and the retrieved reference feature information.

Abstract: An electronic camera detects a person's face image from an object image obtained by photographing an object, executes an enlarging process on the detected face image so as to obtain a face image whose face size is suitable, and displays the face image which is enlarged into the suitable size on a display device. When a plurality of people are present on the object image, the enlarged face images are switched by an image operating switch. As a result, the switched face image is displayed on the display device.

The invention also relates to a composition for oral cavity containing a peptide in which arginine and histidine bind alternately. Preferably, the invention includes a composition for oral cavity including the peptide of a pentamer of (arginine-histidine).

Abstract: A camera divides a light beam having passed through a taking lens unit into two light beams. One light beam forms an image on a silver salt film. Another light beam forms an image on a CCD. A light path for said another light beam is provided with an aperture diaphragm. The taking lens unit has an aperture diaphragm. Said two aperture diaphragms are correlatively controlled by a controller incorporated in the camera.

Abstract: An image observation device which is so arranged that a user can look an image in through an ocular window thereof with the device being fitted to the user's head for example, that the image changes in linkage with movement of the user's head, and that unnecessary change of the image is prevented during the observation. The image observation device includes an eye access detector for detecting whether the user's eyes approach thereto or not, and includes, a controller by the operation of which the image changes in linkage with movement of the user's head only if the eye access detector detects that the user's eyes approach thereto, and by the operation of which the image does not change in linkage with movement of the user's head if the eye access detector does not detect that the user's eyes approach thereto.

Abstract: In a moving picture decoding display apparatus and moving picture decoding display method according to the present invention, moving picture decoder 101 decodes a moving picture signal, RGB matrix manipulation section 103 converts the decoded video signal in YCbCr format into a video signal in RGB format, contrast/brightness adjusting section 104 adjusts the contrast and brightness of the video signal in RGB format, and liquid crystal display module section 110 displays the adjusted video signal on liquid crystal panel 109. At this point, operation control section 105 switches on and off the operation of RGB matrix manipulation section 103 and contrast/brightness adjusting section 104 corresponding to the actual frame rate in moving picture decoder 101, and only when the operation is “on”, the section 105 controls so that the video signal from contrast/brightness adjusting section 104 is stored in video RAM 107 in liquid crystal display module section 110.

Abstract: A storing-reproducing unit 200 recognizes a free space of a contents storage area by a storage-area-administrating device, sets a recording timing duration based on the recognized free space of the contents storage area, and selects a schedule information of a contents to be recorded from recording schedule list information. Hence, frequency of storing the contents in the HDD 270 can be reduced, thereby avoiding that the contents which has not yet watched is erased by self-erasing, so that the contents can be effectively recorded. Therefore, a user can secure flexibility in time in watching the contents.

Abstract: A storing/reproducing device includes a storing controller that recognizes programming information read out from timer recording list information and the data size of a content corresponding to the programming information, and compares the data size with free spaces of an automatic recording area 272 and a manual recording area 273 both forming a content recording area 271, the free spaces being recognized by a storing area manager. When the content is recorded based on the programming information set with input operation by a user, the storing controller records the content in the automatic recording area 272 if the storing controller judges that there is not enough free space in the manual recording area 273. Accordingly, other pieces of information will not be recorded in the manual recording area 273, thereby securing free space in the manual recording area. Therefore, manual recording with the input operation by the user can surely be performed.

Abstract: An image display apparatus has an observation room for housing an observer, and the side faces, floor face, and ceiling face of the observation room are used as screens, onto which images displayed on a smaller number of image display devices than the number of screens are projected. At least one image display device displays, on a time-division or screen-division basis, images to be projected onto two or more screens so that images are projected onto all of the screens.

Abstract: A projector, which projects color images using the three liquid crystal panels (41-43) while cooling them by the fans (611-613) for G, R, and B panels, comprises the level calculation unit (711) for finding the intensity levels of the R, G, and B components of image signals, the level calculation unit (721) for finding the voice levels of voice signals, the fan control unit (73) for controlling the numbers of revolutions of the fans (611-613), and the memory (761) for storing the cumulative amount of lighting time of the lamp (21). As the intensity levels get higher, the numbers of revolutions of the fans are increased, and as the cumulative amount of lighting time becomes larger, the numbers of revolutions of the fans are decreased. As a result, unnecessary noises caused by the fans (611-613) can be reduced while the liquid crystal panels (41-43) are properly cooled.
