摘要： When a digital camera is set to retrieval mode, a map-style retrieval screen having a matrix structure is displayed on a display device. The digital camera searches for images photographed in the regions corresponding to each cell in the matrix structure, based on shooting location information appended to the images. The number of found images is displayed within each cell. When the user inputs a zoom in or zoom out command, the regions corresponding to each cell are made smaller or larger, according to the command. At the same time, a new retrieval is performed for images photographed in the regions corresponding to each of the modified cells. The number displayed within each cell is updated according to the number of images found in the new retrieval. When a single cell is selected, a list view of the images photographed in the region corresponding to the selected cell is displayed.

摘要： A permanent magnet generator incorporated in a diskette that can be inserted into a floppy disk drive is disclosed. In the permanent magnet generator, electric power is generated as a rotor is caused to rotate at a revolution twice to ten times as high as that of the drive shaft of a floppy disk drive by transmitting the rotation of the drive shaft to a rotor via a speed increasing mechanism incorporated in a diskette. Since the cogging torque of the generator is reduced, the rotor can be caused to rotate with a small drive torque. This allows the generator to produce a high output.
摘要翻译：公开了一种结合在可插入软盘驱动器的软盘中的永久磁铁发生器。在永久磁铁发电机中，当通过将驱动轴的旋转传递给转子时，通过将驱动轴的旋转传递到转子而使转子旋转的速度是软盘驱动器的驱动轴的两倍至十倍的旋转，产生电力结合在磁盘中的增速机制。由于发电机的齿槽转矩减小，所以能够以小的驱动转矩使转子旋转。这允许发电机产生高输出。
