Abstract

A method and system for providing a display on a device to which a detachable solid state memory devices, which includes a plurality of memory blocks, is attached. The method includes the steps of determining to which of a plurality of broadcasting system standards a detected size of each of the memory blocks in the solid state memory device corresponds, and providing a display on an apparatus to which the solid state memory device is attached, such as an electronic still camera, based on the detected size. In a preferred embodiment, the broadcasting standards are NTSC (National Television Systems Committee) and PAL (Phase Alternation Line). A user is warned when a detected size of each of the memory blocks is not a predetermined size, thus, not the correct broadcasting system standard for the apparatus. Each of the memory blocks stores data corresponding to one picture image.

Claims

1. A method for providing a display on a device to which a detachable solid state memory device which comprises a plurality of memory blocks is attached, said method comprising the steps of:

determining to which of a plurality of broadcasting system standards a detected size of each of the memory blocks in the solid state memory device corresponds; and

providing a display on the device to which the solid state memory device is attached based on the detected size in order to display information corresponding to a size of the memory blocks of the solid state memory device, said providing step providing a characteristic display when the detected size of the memory blocks of said solid state memory device does not correspond to a predetermined size.

2. A method according to claim 1, further comprising a step of warning a user when the detected size of each of the memory blocks is not a predetermined size.

3. A method according to claim 1, further comprising a step of controlling writing of data into the solid state memory device, according to the detected size.

4. A method according to claim 1, further comprising a step of providing a semiconductor memory as the solid state memory device.

5. A system for displaying information on a display, said system comprising:

a detachable memory device which includes;

a plurality of memory blocks, and

providing means for providing information identifying to which of a plurality of broadcasting system standards a size of each of the memory blocks corresponds; and

an apparatus attached to said detachable memory device, which includes;

means for receiving the information provided by said providing means, and

display means for providing a display based on the information received by said receiving means in order to display information corresponding to a size of the memory blocks of the solid state memory device, said display means providing a characteristic display when the detected size of the memory blocks of said solid state memory device does not correspond to a predetermined size.

6. A system according to claim 5, wherein said apparatus further comprises means for converting an image into image data to be written into said detachable memory device.

7. A system according to claim 5, wherein said display means provides a warning when the displayed information indicates that a size of the memory block of the solid state memory device is not a predetermined size.

8. A system according to claim 5, further comprising means for controlling writing of data into said detachable memory device, according to the information received by said receiving means.

9. A system according to claim 5, wherein each memory block stores data corresponding to one picture image.

10. A system according to claim 5, wherein said detachable memory device is a semiconductor memory.
