摘要： An electronic camera records files of photographed images in such a manner that files of images photographed under different photographing circumstances (e.g., different exposure modes, compression rates, or photographing dates/times) can readily be distinguished. In certain preferred embodiments, a data management index corresponding to a first photographing circumstance is recorded at a first hierarchy level and a file name assigned to an image photographed under the first photographing circumstance is recorded in association with the file management index at a hierarchy level different from the first hierarchy level. A second data management index corresponding to a second photographing circumstance or a file name assigned to an image photographed under a second photographing circumstance is also recorded at the first hierarchy level.

摘要： An electronic still camera, for recording the image signal in compressed state in a memory medium such as a memory card, is provided with a calculation circuit, for calculating the remaining number of still recordable frames in the memory medium in more reliable manner, and the number of already recorded frames and the remaining number of still recordable frames are simultaneously displayed in order to inform the photographer of the remaining state of the memory card in securer manner.The remaining frame number is calculated in securer manner by detecting the remaining capacity of the memory card and dividing the remaining capacity with the amount of compressed signal averaged over the latest 100 image frames. A display device is provided for indicating thus determined remaining frame number together with the number of already recorded frames.For calculating the remaining frame number in more reliable manner, there are determined the average data amount of the recorded frames, the standard deviation, and the remaining capacity of the memory card, and the minimum remaining frame number is determined by dividing the remaining capacity with the average data amount plus standard deviation, while the maximum remaining frame number is determined by dividing the remaining capacity with the average data amount minus standard deviation. Also there is provided a display device for indicating the remaining frame number in the form of a range defined by the minimum and maximum remaining frame numbers.

摘要： An image data recording method in a digital still video camera capable of selecting one of the single shot mode for photographing and recording only a single image and the sequential shot mode for sequentially photographing and recording a plurality of images comprises the steps of distinguishing whether a recorded image was photographed in the single shot mode or in the sequential shot mode, giving a file name correspondingly to the photographed image, and recording the photographed image. File names for each single shot image may be stored at a given hierarchy level. A name (e.g., a subdirectory name) representative of a plurality of sequential shot images may be stored at the same level as the single shot file names and file names of the sequential shot images stored under the representative name at a different hierarchy level.
