    • In principle, an I-frame is inserted every 50 frames and other frames are made P-frames. If the maximum amount of data that can be received by a terminal device to which a transmission is to be made is 300 KB, then frames up to a 144th frame for which the amount of data after compression will not exceed 300 KB is adopted as a first partitioned moving picture file. Since the 145th frame is the leading frame of the next partitioned moving picture file, it is made an I-frame. Frames from the 145th frame to a 289th frame are made a second partitioned moving picture file, and frames from a 290th frame to a 411th frame are made a third partitioned moving picture file. Since the leading frame of a partitioned moving picture file represents one complete frame, the moving picture can be reproduced and the number of partitions can be reduced.
    • 原则上,每50帧插入一个I帧,其他帧是P帧。 如果要进行发送的终端设备可以接收的最大数据量为300KB,则采用压缩后的数据量不超过300KB的第144帧的帧作为 第一分区运动图像文件。 由于第145帧是下一个划分的运动图像文件的前导帧,所以它被制成I帧。 将从第145帧到第289帧的帧作为第2分割运动图像文件,将从第290帧到第411帧的帧作为第3分割运动图像文件。 由于分割运动图像文件的前导帧表示一个完整帧,因此可以再现运动图像,并且可以减少分割数。

    • First and second data areas are defined in an image file, and each area is defined to have an image data recording area and a header data recording area. When the image file is reproduced, header data in a first header data recording area at the leading end is read and first image data that has been recorded in the first image data recording area is reproduced. If an image file reproducing apparatus is one that can reproduce second image data that has been recorded in the second data area, then the second image data is read from the second area and reproduced. The first image data is data that has undergone JPEG compression, and the second image data is data that has not been compressed. Since the compressed first image data and uncompressed second image data can be stored in one file, an increase in number of files can be reduced even if there is an increase in types of image format.
    • 第一和第二数据区域被定义在图像文件中,并且每个区域被定义为具有图像数据记录区域和头部数据记录区域。 当再现图像文件时,读取在前端的第一标题数据记录区域中的标题数据,并且已经记录在第一图像数据记录区域中的第一图像数据被再现。 如果图像文件再现装置是可以再现已经记录在第二数据区域中的第二图像数据的图像文件再现装置,则从第二区域读取第二图像数据并再现。 第一图像数据是经过JPEG压缩的数据,第二图像数据是未被压缩的数据。 由于压缩的第一图像数据和未压缩的第二图像数据可以存储在一个文件中,所以即使图像格式的类型增加,也可以减少文件数量的增加。

    • An input apparatus reads a patient ID from an ID card and transmits it to a computer. On the basis of the patient ID, the computer obtains corresponding patient information containing a photograph of the patient's face and the patient's name, from a medical database, and then transmits the patient information to the digital camera together with the patient ID. The digital camera displays the patient information on the liquid crystal monitor to enable confirmation of the patient, who is a subject to be photographed. After the patient has been confirmed, the patient ID is filled in a header part of an image file for the image photographed using the digital camera, and the image file is transmitted to the medical database or the like. Thus, when identification information on the subject is recorded in connection with the photographed image, the input of the identification information is simplified, and the correspondence between the subject identification information input before photographing and the subject to be photographed can be easily confirmed. Further, the digital camera obtains locational information from a car navigation apparatus. The locational information is classified into added-to-image information added to the subject image (GPS information indicative of latitude, longitude, and altitude) and display information associated with the added-to-image information (the place name corresponding to the GPS information). The digital camera stores the location information obtained in a non-volatile memory and displays the display information (place name) of the locational information on the liquid crystal monitor of the camera. Subsequently, after photographing has been completed, the added-to-image information (GPS information) of the locational information stored in the non-volatile memory in connection with the image. Thus, if additional information input from an external device is recorded in connection with the subject image, the camera can be used to easily check what added-to-image information is used, whether or not the added-to-image information is correct as information to be added to the subject image, and the like.
