Electronic still camera using variable-length data compression for storing still image signals
First Claim
1. An electronic still camera for recording a plurality of one-frame electronic still image signals, comprising:
- image pick-up means for generating an electronic still image signal;
A/D conversion means for converting the electronic still image signal generated by said image pick-up means into a digital signal;
data compressing means for applying variable-length encoding data compression to the digital signal converted by said A/D conversion means so as to obtain compressed image data;
recording means for recording the compressed image data obtained by said data compressing means in a recording medium having a predetermined recording capacity, with a plurality of one-frame compressed image data being assigned spaces, respectively, on said recording means, and wherein the size of a given space is determined in accordance with amount of data in the one-frame compressed image data recorded therein;
calculating means for calculating an estimated count of recordable electronic still image frames which can be recorded in the recording medium in accordance with quantitative data per frame associated with the plurality of one-frame compressed image data recorded in the recording medium by said recording means and quantitative data associated with the recording capacity of the recording medium; and
indicating means for indicating the estimated count of the recordable electronic still image frames calculated by said calculating means.

Abstract
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.
