Combination still and motion picture electronic camera/recorder
First Claim
1. A combination still and motion picture electronic camera/recorder comprising:
- a sensor for spatially sampling an optical image corresponding to picture elements to convert it into an electric signal;
a readout circuit, operatively connected to said sensor, for reading out stored information signals of the sensor at a still-mode scanning speed in the case of taking a still picture and for reading out the stored information of the sensor at a movie-mode scanning speed in the case of taking a motion picture;
a control unit, operatively connected to said readout circuit, for generating scanning synchronizing signals for still pictures for operating the readout circuit at the still-mode scanning speed and scanning synchronizing signals for motion pictures for operating the readout circuit at the movie-mode scanning speed;
a mode select unit, operatively connected to said readout circuit and said control unit, for sending to the recording unit, in accordance with the scanning synchronizing signals for still pictures, information signals corresponding to all picture elements in the case of signals being read out from the sensor by the readout circuit at the still-mode scanning speed and for sending to the recording unit, in accordance with the scanning synchronization signals for motion pictures, information signals such that at least one of the number of picture elements per frame and the number of quantized bits per picture element is smaller than the number of picture elements per frame and/or the number of quantized bits per picture element in the case of taking a still picture when the information signals are read out from the sensor by the readout circuit at the movie-mode scanning speed; and
a recording unit, operatively connected to said control unit and said mode select unit, for recording signal at a fixed speed.

Abstract
An electronic combination still-movie camera with which it is possible to take both still and motion pictures through the use of a simple recording device of audio grade. Stored information from optoelectro transducers is read out by a readout circuit at a still-mode scanning speed in the case of taking a still picture and at a movie-mode scanning speed in the case of taking a motion pictures. In the former case, signals corresponding to all pictures elements are sent to a recording unit for recording and, in the latter case, signals such that at least one of the number of picture elements per frame and the number of quantize bits per picture element is smaller than in the former case are sent to the recording unit for recording.
