Abstract
Abstract This invention relates to an electronic still camera for imaging a desired object through an imaging device, and provides a continuous-shot means with large-capacity recording. When image data RAW retrieved through predetermined imaging means is data processed to record the image on a recording medium, a high buffer memory with high speed is provided which stores image data RAW temporarily.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
259 words
An electronic still camera having first operational mode for creating a single image of a light image from an object, and a second operational mode for continuously imaging said light image, said camera comprising: an imaging device for photoelectronically converting said light image to an output image signal; image data processing means for processing said image signal into digital image data; memory means for temporarily storing said image data, said memory means having a memory access time; recording means for recording said image data on the recording medium, said recording means having a recording access time which is longer than said memory access time; compression means for compressing the image data from said image data processing means; switching means for selectively supplying said image data to said compression means and to said memory means; control means for supplying the image data from said image data processing means directly to at least one of said recording means and compression means in said first operational mode, and for supplying the image data from said image data processing means to said memory means in said second operational mode; means for converting the image data from said image data processing means into image data having higher resolution; and switching means for selectively supplying said image data to said means for converting and to said memory means, wherein said control means controls said switching means to supply said image data to said converting means in said first operational mode, and to supply said image data to said memory means in said second operational mode.
Claim 2
Dependent Claim
259 words
An electronic still camera having first operational mode for creating a single image of a light image from an object, and a second operational mode for continuously imaging said light image, said camera comprising: an imaging device for photoelectronically converting said light image to an output image signal; image data processing means for processing said image signal into digital image data; memory means for temporarily storing said image data, said memory means having a memory access time; recording means for recording said image data on the recording medium, said recording means having a recording access time which is longer than said memory access time; compression means for compressing the image data from said image data processing means; switching means for selectively supplying said image data to said compression means and to said memory means; control means for supplying the image data from said image data processing means directly to at least one of said recording means and compression means in said first operational mode, and for supplying the image data from said image data processing means to said memory means in said second operational mode; means for converting the image data from said image data processing means into image data having higher resolution; and switching means for selectively supplying said image data to said means for converting and to said memory means, wherein said control means controls said switching means to supply said image data to said converting means in said first operational mode, and to supply said image data to said memory means in said second operational mode.
Claim 3
Dependent Claim
19 words
The electronic still camera according to claim 1, wherein said memory means comprises a static random access memory (SRAM).
Claim 4
Dependent Claim
16 words
The electronic still camera according to claim 2, wherein said recording medium comprises an magneto-optical disc.
Claim 5
Dependent Claim
16 words
The electronic still camera according to claim 2, wherein said recording medium comprises a flash memory.
