A digital still camera in which a CPU retrieves, when the digital still camera has been switched ON, whether any directory prepared by an external device (other maker's device: e.g., a digital still camera produced by some other maker or a PC) exists on a memory card or not, displays, when it is retrieved that the directory prepared by the external device exists thereon, a message or sign to that effect on an LCD, and reports it to an operator, in addition, the CPU has, as a reproduction mode, a mode for reproducing also a file in a directory prepared by an external device on the memory card.

Digital still camera and control method for accessing image and speech data files

A digital camera includes a memory configured to store image data including thumbnail image data and a display configured to display the thumbnail image data. Further, a controller is configured to control the display of the thumbnail image data and to display page data with the thumbnail image data. The page data can include data of a currently displayed page and data of a total number of pages, and further an operator can set and reset the number of thumbnail images which form one page. Further, the operator can change this setting of the number of thumbnail images in one page while selecting a specific thumbnail image of a currently displayed page of thumbnail image data. The controller can calculate the total number of pages in a currently displayed page, and can recalculate this data if the number of thumbnail images in a page is reset by an operator. Further, each of the pages can be accessed sequentially and the first and last pages can be viewed as sequential pages. Segment data can also be displayed and can be recalculated if a number of thumbnail images which form one page is reset by an operator.

Digital camera and method which displays a page number of a displayed page

A digital camera which captures images and converts the images to a digital form. The digital form of the images is compressed and written into a memory card along with Disk Operating System (DOS) information describing the memory card and files including bios parameters, File Allocation Table (FAT) information, and directory information. When the DOS information within the memory card needs to be changed, the FAT information of the memory card and only a portion of the directory information is read and transferred to a memory within the camera. The directory information which has been loaded into the camera is checked to determine if it is the necessary directory information. If it is not, further directory information is loaded into the memory of the camera. After editing of the FAT and directory information, the edited information is written back into the memory card.

Method and system for processing DOS information within a digital still

A still picture recorder has a video signal producing circuit for converting a picked-up image into a video signal and a memory section for storing information as a still picture from video information transmitted from the video signal producing circuit by a supplied control signal, the memory section transmitting the still picture information stored in accordance with the control signal. A recorder then records the video information to a recording medium in accordance with the control signal. A switch for indicating that the still picture is recorded to the recorder and a control section for transmitting the control signal to the memory section and the recorder by operating the switch are also utilized.
