Abstract
Abstract Audio signals that correspond with still images are recorded in an electronic still camera on the same magnetic disc as the visual images. By time-base compressing the audio signal and dividing each record track into a number of segments, ten seconds of audio can be recorded for each image without requiring a large processor memory. Identification codes are added to the time-base compressed audio to permit multiple audio tracks to be associated with a recorded image less than the allotted duration, so that a number of images can be recorded in rapid succession without waiting for each of the successive allotted audio time periods to expire.
