Electronic still camera using variable-length data compression for storing still image signals

摘要

An image pick-up section generates an electronic still image signal. An A/D conversion section converts the electronic still image signal generated by the image pick-up section into a digital signal. A data compressing section causes variable-length encoding data compression to the digital signal obtained by the A/D conversion section so as to obtain compressed image data. A recording section records the image data compressed by the data compressing section in a recording medium having a predetermined recording capacity. A calculating section calculates an estimated count of electronic still images which can be recorded in the recording medium in accordance with quantitative data associated with the image data recorded in the recording medium by the recording section and quantitative data associated with the recording capacity of the recording medium. An indicating section indicates the estimated count of the recordable electronic still images calculated by the calculating section.
