Abstract
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 m…
