Abstract
Abstract A digital still video camera including a camera processor which processes image data of a subject, a recording processor which generates recording data based on the processed image data, a recording controller which controls recording of the recording data to a recording medium, a memory which stores image data processed by the camera processor and recording data recorded in the recording medium, a control device which controls the camera processor, the recording processor, and the recording controller, and an evacuating/writing device which interrupts control by the control device and evacuates/writes the recorded recording data between the recording medium and the memory.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A digital video still camera comprising: a camera processor which processes image data of a subject; a recording processor which generates recording data based on said image data which have been processed by said camera processor; a recording controller which controls recording of said recording data to a recording medium; a memory which stores said image data which have been processed by said camera processor; a control device which controls said camera processor, said recording processor, and said recording controller; and an evacuating/writing device which interrupts said control device when an evacuate/write operation is necessary and controls said camera processor and said recording controller to perform said evacuate/write operation wherein: said recording data which have been recorded in said recording medium are transferred to said memory, said recording medium is erased, and a portion of said recording data which has been transferred to said memory is transferred to said recording medium.
Claim 2
Dependent Claim
151 words
A digital video still camera comprising: a camera processor which processes image data of a subject; a recording processor which generates recording data based on said image data which have been processed by said camera processor; a recording controller which controls recording of said recording data to a recording medium; a memory which stores said image data which have been processed by said camera processor; a control device which controls said camera processor, said recording processor, and said recording controller; and an evacuating/writing device which interrupts said control device when an evacuate/write operation is necessary and controls said camera processor and said recording controller to perform said evacuate/write operation wherein: said recording data which have been recorded in said recording medium are transferred to said memory, said recording medium is erased, and a portion of said recording data which has been transferred to said memory is transferred to said recording medium.
