Abstract: An information processing device for facilitating a user's recognition of relevant information when relevant information concerning a predetermined menu item of a digital household electronic appliance, for example, is presented to the user.

Abstract: An image processing method is provided for detecting the position of a specific subject from a moving image and combining a display of detection result indicating the detected position with the moving image. The image processing method includes a step of determining, depending on a display time of the detection result, whether the detection result should be continuously displayed, when the subject cannot be detected during the display of the detection result combined with the moving image.

Abstract: When a plurality of items of data are sequentially read and reproduced from a data storing means which stores the data, data suited to a user's mood at the moment or a situation is selected to be reproduced without needing any complex operation.

Abstract: In a content output apparatus which is connected to at least one content playback apparatus, lists of content which are respectively reproducible by the connected content playback apparatuses are acquired. When the acquired lists of the content are output in order for a user to select any of the listed content, the content playback apparatus capable of playing back the selected content is specified, and a playback instruction signal for instructing the specified content playback apparatus to play back the selected content is output so as to output a signal which is pertinent to the content played back by the content playback apparatus. As a result, the content output apparatus is more convenient to use.

Abstract: The coordinate-position input device has a frame with a reflecting member for recursively reflecting light provided in an inner side from four edges of the frame forming a rectangular form. Two optical units irradiate light to the reflecting members and receive the reflected light. With the mounting member(s) the frame can be detachably attached to a white board. The two optical units are located at both ends of any one of frame edges forming the frame, and at the same time the two optical units and the frame body are integrated to each other.

Abstract: The present invention is relative to an apparatus for retrieving desired music number data from a large number of music number data recorded on a large capacity recording medium. The apparatus includes memories (11), (12) in which to store a plural number of music number data, a rhythm inputting unit (13) to which a rhythm pattern of a music number is input, a retrieving unit (18) for retrieving music number data stored in the memory (11) based on the input rhythm pattern input at the rhythm inputting unit (13) and a display unit (23) in which to display the information relevant to the music number data as found out by the retrieving unit (18). The retrieving unit (18) detects plural registered rhythm patterns which are stored in the memory (11), (12) and which are similar to the input rhythm pattern, while retrieving plural content data corresponding to the plural registered rhythm patterns. Moreover, the retrieving unit (18) is responsive to the user input to select one of the plural content data.

Abstract: A coordinates input device comprises, two optical units which emit a light flux onto a panel and also receive the light flux. The coordinates input device then calculates the coordinates of an obstacle in the light flux on the panel based on the result of light flux detection in the optical units and the dimensions of the panel. The coordinates input device further comprises a sound-wave generator and a sound-wave detector for measuring the dimensions, used in the calculation of the coordinates, of the panel.

Abstract: A coordinate-position detecting device comprising a white board as a coordinate-position entry area, and three reflecting members each for recursively reflecting light from two optical units. The angle between the write-in surface of the white board and the reflecting surface of the reflecting member at the bottom is an obtuse angle. Further, of angles obtained by dividing the above angle by a horizontal surface, the angle between the horizontal surface and the reflecting surface is an acute angle.

Abstract: A device for securing an operation panel on an office machine such as a copier or the like where the parts to be engaged between the operation panel and the machine frame are arranged symmetrically relative to a rotating axis of the operation panel. Electrical wiring extending from the interior of the machine to the operation panel are provided with sufficient lengths, so that the operation panel can be secured to the machine frame in either of two positions rotated from one each other through an angle of 180.degree.. The engagement between the operation panel and the machine frame is of a snap or a slide latch type of coupling.
