    摘要: An electronic camera electronically records an optical image by using a non solid-state memory and includes an image pickup element, an image pickup section, and an external recording section. The image pickup section includes a solid-state memory means for digital-recording at least one-frame image signals supplied from the image pickup element. The external recording section includes a non solid-state memory means, and a D/A converter for analog-recording a digital image signal supplied from the image pickup section on the non solid-state memory means. The image pickup section and the external recording section are detachable.

    摘要: An electronic camera has an image pickup section and a detachable recording section. The image pickup section includes an image pickup element for converting an optical image into an analog image signal. The image pickup section also includes an analog-to-digital converter for converting the analog image signal into digital image signals which are stored in a digital memory within the image pickup section. The detachable recording section includes a digital-to-analog converter for converting the digital signal output from the image pickup section into an analog signal which is recorded in an analog memory within the recording section.

    摘要: In the system disclosed, a feedback circuit connects the output of the last of a plurality of cascaded amplifier stages to the input of the first stage. A photoelectric transducer is connected to one of the stages. The feedback connection compresses the output signal relative to the signal at the photoelectric transducer, logarithmically. Preferably all the stages are linear and the feedback circuit is linear so that no logarithmic members are required. Preferably each of the stages is composed of an amplifier and a connection corresponding to an emitter-follower connection. A suitable system then utilizes the compression characteristic in a shutter control. This system may use a second compression circuit comparable to the first. Additional photographic information may be applied to the input of any of the stages in either compression circuit.
