Abstract
Abstract A solid-state still camera includes a detector (304a, 306a) for detecting how much track space is already occupied and producing a detector signal for every occupied track. A counter (521, 522) counts the detector signals and produces a counter signal representative of the number of occupied tracks. The solid-state still camera is also provided with a manually operable mode selector for selecting video recording mode from among a plurality of different modes, such as frame mode and filed mode. An arithmetic circuit (523) receives counter signals and a selected mode indicative signal. The arithmetic circuit (523) derives the number of pictures that can be taken based on the counter signal value and the selected mode indicative signal. The value derived by the arithmetic circuit is displayed on a visual display. Preferably, the solid-state still camera also includes an audio recording feature. The detector (304a, 306a) also detects the tracks occupied by recorded audio signals. The indicator makes it possible to conveniently known the number of blank tracks available for taking pictures or recording audio sounds.
