A method for an apparatus including an acquisition unit for acquiring moving image data, and a recording unit for recording the acquired moving image data in a loaded recording medium, includes determining whether the recording medium is a recordable and non-erasable recording medium, and if the recording medium is a recordable and non-erasable recording medium, controlling the recording unit so as to automatically stop recording of the moving image data according to the fact that a predetermined time has elapsed from the recording start of the moving image data, and if the recording medium is not a recordable and non-erasable recording medium, controlling the recording unit so as not to automatically stop recording of the moving image data, even if the predetermined time has elapsed from the recording start of the moving image data.

Recording apparatus

A recording or playback apparatus classifies privacy-related information such as information concerning an operation of an apparatus and information for identifying an operator into, e.g., an individual identification information category, playback contents information category, apparatus maintenance information category, and photographing environment information category, and controls recording, playback, display, transfer, or erase of the privacy-related information by the apparatus in accordance with the classified categories.

Recording apparatus, playback apparatus, and privacy protecting method

A recording/reproducing apparatus has a network mode for transmitting and receiving image data through a network and a normal mode for recording and reproducing image data without connecting to a network. In a mode capable of switching between the network mode and the normal mode, the apparatus prohibits the data recording operation on a recording medium and the data erasing operation on the recording medium regardless of whether an accidental-recording prevention means is in a recording-allowed state or in a recording-prohibited state.

A control apparatus controls information exchange among portable terminals which perform wireless communication via a communication network. A unit accepts a specific information-provision request from a first portable terminal. A unit determines a prescribed area based on the accepted information-provision request. A unit sends the information-provision request to a second portable terminal in the prescribed area. A unit accepts a response to the information-provision request from the second portable terminal. A unit sends the response to the information-provision request to the first portable terminal.

Information exchange system

Images sensed through object lensesR andL, having zoom lenses, with image sensorsR andL are processed by image signal processorsR andL, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor, where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensorsR andL and that they fall within the both focal depths of the image sensorsR andL.

When a region of interest of an image is compressed with high quality by an image sensing apparatus, such as a digital camera or the like, the region of interest (ROI) can be compressed by a compression coefficient different from that of other regions of the image according to the so-called JPEG 2000 method. However, setting the ROI is a complicated operation for a user. In the present invention, when a continuous photographing mode is not set, a single image sensing operation is assumed and the ROI is automatically set in a first region, which is the largest of three regions. Whereas in the continuous photographing mode, if a low-speed mode is set, the ROI is set in a second region smaller than the first region, and if a high-speed mode is set, the ROI is set in a third region, which is the smallest. In other words, the ROI is automatically set in the largest region in the single photographing mode, and when the continuous photographing mode is set, the ROI is automatically set larger in the low-speed mode than in the high-speed mode.
