    • A manipulation of the shutter release button mechanism causes the first signal to be detected by the control processor, which selects in turn the still picture mode effecting still picture recording on a data recording medium. A further manipulation of the release button mechanism causes the second signal to be detected by the control processor, which selects in turn the movie picture mode effecting movie picture recording on the data recording medium. In the still picture mode, pixel signals generated by the image sensor are transferred on the frame basis, while in the movie picture mode, pixel signals are transferred on the interlaced field transfer basis. The pixel signals are converted into corresponding digital image data to be stored in the frame memory, from which the control processor read the stored image data. In the still picture mode, a frame of image data is sequentially read out from the memory and compressed as a still image to be recorded on the oprical disk. In the movie picture mode, part of a frame of image data is read out from the memory with any movement of the camera compensated for on the basis of signals obtained from the movement sensor and compressed as movie images to be recorded on the same optical disk.
    • 快门释放按钮机构的操作使得控制处理器检测到第一信号,控制处理器依次选择在数据记录介质上实现静止图像记录的静止图像模式。 释放按钮机构的进一步操作使得控制处理器检测到第二信号,控制处理器依次选择影响数据记录介质上的电影图像记录的电影图像模式。 在静止图像模式中,由图像传感器生成的像素信号以帧为基础传送,而在电影图像模式中,以隔行扫描的场传送为基础传送像素信号。 将像素信号转换成相应的数字图像数据以存储在帧存储器中,控制处理器从该存储器读取存储的图像数据。 在静止图像模式中,从存储器中顺序地读出一帧图像数据,并将其压缩为要被记录在opical磁盘上的静止图像。 在电影图像模式中,通过基于从移动传感器获得的信号进行补偿的相机的任何移动,从存储器读出一帧图像数据的一部分,并将其压缩为要记录在同一光盘上的电影图像 。
