Abstract: A digital camera which converts a picked-up optical image of an object into digital image data comprises a memory card slot part and a disk drive part. Digital image data can be transferred between a memory attached to the memory card slot part and a small disk inserted into the disk drive part.

Abstract: A digital camera can be selectively installed in a cradle in whichever states where an imaging lens is arranged toward the outside in the cradle or where a liquid crystal display portion is arranged toward the outside in the cradle, and a device connected to the cradle and the digital camera is allowed to perform a linkage operation.

Abstract: There is disclosed a digital still camera in which a direction and speed of a tracing operation by user's fingertips on a touch panel are judged and a dynamic image reproduction process is executed in accordance with the direction and speed. For example, fast forward/rewind reproduction of a dynamic image is executed in response to a long and fast tracing operation to the right from the left or to the left from the right.

Abstract: A display panel includes row and column electrodes. Capacitive light-emitting elements are provided at crossing portions of the row and column electrodes. A drive unit drives the display panel in response to an input image signal. The drive unit includes a column electrode driver for applying a pixel data pulse to each of the column electrodes. The pixel data pulse has a pulse voltage corresponding to pixel data derived from the input image signal. The column electrode driver includes a power source circuit for generating a resonance pulse power source voltage having a predetermined resonance amplitude. The power source circuit also applies the. resonance pulse power source voltage to a power source line. The column electrode driver also includes a pixel data pulse generator circuit for selectively connecting the column electrodes with the power source line based on the pixel data, to apply the pixel data pulse to the column electrodes.

Abstract: A plasma display panel driving method and a plasma display apparatus which can reduce power consumption. A selective discharge is generated at least once for selectively setting each of discharge cells of a plasma display panel either to a lit discharge cell state or to an unlit discharge cell state in accordance with a video signal. In this case, the number of times the selective discharge is generated is changed in accordance with the power consumption associated with the selective discharge.

Abstract: A list of the selected and input virtual directory names are displayed on the display screen by operating the album key and a predetermined virtual directory name is selected from the list of the virtual directory names being displayed on the display screen by operating any of the movement keys and the determination key. The image data obtained as a result of an imaging operation are recorded in a directory corresponding to the selected virtual directory name and conforming to the DCF Standard.

Abstract: A virtual directory name (TRAVEL) having a form not specified in the DCF Standard is employed as a recording name in a directory (101TOSHI) recorded in a file management structure complying with the DCF Standard, whereas a virtual directory management file which corresponds to the virtual directory name (TRAVEL) and the name (101TOSHI) of a directory of the DCF Standard corresponding thereto is created to record in a recording medium.

Abstract: A method and an apparatus of processing files according to the present invention comprise a first and second apparatus for recording data in a manner complying with the DCF standardized file-managing structure. In the method and apparatus, a file for management is formed with respect to a directory recorded in a manner complying with the DCF standardized file-managing structure. In the file, a virtual directory name in a form not defined as the DCF standard is to be compatible with a DCF standardized directory that corresponds to the virtual directory name. The file for management is to be maintained, whereas data is transmitted between the first and second apparatus.

Abstract: A multiscan compatible horizontal deflection driving circuit prevents the flow of an excessive current through a transistor in a horizontal deflecting circuit when the frequency of a horizontal synchronization signal is switched. In the horizontal deflection driving circuit according to the invention, when a frequency of an H sync pulse of an input composite video signal decreases, a driving power source voltage is reduced earlier than a reduction of a frequency of a horizontal driving pulse, thereby preventing an excessive collector current from flowing in the transistor in the horizontal deflecting circuit.
