Abstract
Abstract In an electronic still camera operable with a memory card or similar storage medium removably mounted thereto, a first controller causes, before a continuous shoot mode or similar mode operation begins, a memory card to develop attributes information particular to and stored in the card to a second controller. The attributes information include one representative of a storing speed available with the card. Then, the first controller selects a clock frequency of a clock signal which matches the storing speed and provides the card with a reference for operation. The first controller generates a clock signal having the clock frequency selected and sends it to the card together with image data representative of a scene. As a result, the image data are written to the card at a speed synchronous to the frequency of the clock signal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
184 words
An electronic still camera operable with a storage medium which is removably mounted to said camera for storing data and includes a semiconductor memory device, said camera comprising: imaging means for picking up an object and producing image data representative of said object; processing means for processing the image data produced by said imaging means to convert said image data to image data capable of being written to the storage medium; storing means for temporarily storing the image data processed by said processing means; first control means for controlling said processing means and said storing means such that the image data processed by said processing means and then stored in said storing means are written to the storage medium; and second control means for commanding said first control means to read attributes information representative of attributes of the storage medium out of said storage medium and execute operation control matching said attributes information; said first control means controlling, in response to a command from said second control means, a shooting operation of said camera and writing of the image data in the storage medium.
Claim 2
Dependent Claim
184 words
An electronic still camera operable with a storage medium which is removably mounted to said camera for storing data and includes a semiconductor memory device, said camera comprising: imaging means for picking up an object and producing image data representative of said object; processing means for processing the image data produced by said imaging means to convert said image data to image data capable of being written to the storage medium; storing means for temporarily storing the image data processed by said processing means; first control means for controlling said processing means and said storing means such that the image data processed by said processing means and then stored in said storing means are written to the storage medium; and second control means for commanding said first control means to read attributes information representative of attributes of the storage medium out of said storage medium and execute operation control matching said attributes information; said first control means controlling, in response to a command from said second control means, a shooting operation of said camera and writing of the image data in the storage medium.
Claim 3
Dependent Claim
112 words
A camera in accordance with claim 1, wherein said first control means comprises reading means for reading the attributes information out of the storage medium; said second control means comprising: identifying means for identifying the attributes information read out by said first control means; and deciding means for determining, based on the attributes information identified by said identifying means, whether or not the image data can be written to the storage medium by the operation control of said first control means; said first control means controlling, based on a result of decision of said deciding means, the shooting operation of said camera and writing of the image data in the storage medium.
Claim 4
Dependent Claim
58 words
A camera in accordance with claim 2, wherein said first control means comprises: clocking means for selecting and outputting, based on the result of decision of said deciding means, a clock signal for providing the storage medium with a reference for operation; and transferring means for transferring the clock signal and the image data to the storage medium.
Claim 5
Dependent Claim
28 words
A camera in accordance with claim 1, wherein the attributes information include information representative of a storing speed particular to the semiconductor memory device of the storage medium.
Claim 6
Dependent Claim
26 words
A camera in accordance with claim 1, wherein the attributes information include information representative of a kind of the semiconductor memory device of the storage medium.
Claim 7
Dependent Claim
34 words
A camera in accordance with claim 1, further comprising display means for displaying information associated with the attributes information, said second control means transferring information represented by said attributes information to said display means.
Claim 8
Dependent Claim
35 words
A camera in accordance with claim 1, wherein said first control means further comprises setting means for setting, in a continuous shoot mode, an interval between continuous shots on the basis of the attributes information.
