A method of producing a digital image with improved resolution during digital zooming, including simultaneously capturing a first low resolution digital image of a scene and a second higher resolution digital image of a portion of substantially the same scene. A composite image is then formed by combining the first low-resolution digital image and a corresponding portion of the high resolution digital image. Digital zooming of the composite image produces a zoomed image with high resolution throughout the zoom range and improved image quality.

An object of the invention is to make it possible to secure data retained by a cache memory with high reliability without increasing the size or cost of a storage device. When a host-handling processor and a disk processor have recognized occurrence of a power failure, operation of a storage device is continued for about one minute on DC power that is supplied from a battery module. After a lapse of one minute from the occurrence of the power failure, the host-handling processor interrupts the connection between the storage device and a host. Then, the host-handling processor turns off a SW of a host I / F and the disk processor writes, to an HDD, data that have been written to a cache memory. After completion of this processing, the disk processor turns off a SW of the disk I / F and a SW of the HDD. Then, the disk processor causes the battery module to supply DC power only to the cache memory.
