Abstract
Abstract Picture signals entering a picture input device 4 are compressed by a picture compression device 5 for storing the resulting compressed picture data in a secondary storage device 7 via a primary storage device 6 . The picture compression system is switched for recording a moving picture and for recording a still picture by switching picture compression parameters of the picture compression device 5 by a picture compression system switching device 10 between those for moving picture recording and those for still picture recording.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
178 words
A still/moving picture recording apparatus comprising: picture compression means for generating, for a moving picture recording mode, picture data compressed based on compression parameters for moving picture recording, and for generating, for a still picture recording mode, compressed picture data compressed based on compression parameters for still picture recording; and recording means for recording picture data generated by said picture compression means on an exchangeable recording medium, wherein picture data inclusive of the still picture recording mode information specifying that the picture is a still picture is recorded on said recording medium for the still picture recording mode, and wherein said compression parameters for the still picture provide that, in compression encoding the compression parameters for still picture in accordance with MPEG as the standard for encoding, the quantization coefficient of the first macro-block of the picture data be fixed at a pre-set specified value, and wherein the information in which the quantization coefficient of the first macroblock of the picture data is fixed at the pre-set specified value is utilized as the still picture recording mode information.
Claim 2
Dependent Claim
178 words
A still/moving picture recording apparatus comprising: picture compression means for generating, for a moving picture recording mode, picture data compressed based on compression parameters for moving picture recording, and for generating, for a still picture recording mode, compressed picture data compressed based on compression parameters for still picture recording; and recording means for recording picture data generated by said picture compression means on an exchangeable recording medium, wherein picture data inclusive of the still picture recording mode information specifying that the picture is a still picture is recorded on said recording medium for the still picture recording mode, and wherein said compression parameters for the still picture provide that, in compression encoding the compression parameters for still picture in accordance with MPEG as the standard for encoding, the quantization coefficient of the first macro-block of the picture data be fixed at a pre-set specified value, and wherein the information in which the quantization coefficient of the first macroblock of the picture data is fixed at the pre-set specified value is utilized as the still picture recording mode information.
Claim 3
Dependent Claim
144 words
A still picture recording method: wherein, for a moving picture recording mode, picture data compressed based on compression parameters for moving picture recording is generated for recording on a recording medium, wherein, for a still picture recording mode, picture data compressed based on compression parameters for still picture recording is generated based for recording on the recording medium along with the still picture recording mode information specifying that the picture recorded in a still picture, and wherein the compression parameters for still picture provide that, in compression encoding by MPEG as a standard for encoding, the quantization coefficient of the initial macro-block of picture data be fixed at a pre-set specified value, and wherein the information in which the quantization coefficient of the initial macro-block of picture data is fixed at the pre-set specified value is used as the still picture recording mode information.
Claim 4
Dependent Claim
144 words
A still picture recording method: wherein, for a moving picture recording mode, picture data compressed based on compression parameters for moving picture recording is generated for recording on a recording medium, wherein, for a still picture recording mode, picture data compressed based on compression parameters for still picture recording is generated based for recording on the recording medium along with the still picture recording mode information specifying that the picture recorded in a still picture, and wherein the compression parameters for still picture provide that, in compression encoding by MPEG as a standard for encoding, the quantization coefficient of the initial macro-block of picture data be fixed at a pre-set specified value, and wherein the information in which the quantization coefficient of the initial macro-block of picture data is fixed at the pre-set specified value is used as the still picture recording mode information.
