Electronic image pick-up device for a single-lens reflex camera having an interchangeable finder
First Claim
1. An electronic image pick-up device for attachment to a single lens reflex camera of the type which can accept a replaceable optical finder at a finder unit receptacle on the camera body, comprising:
- (a) a casing shaped to fit the finder unit receptacle on the camera body;
(b) a solid state image pick-up element having an image receiving surface arranged within said casing so that an object image provided in the camera is applied on said image receiving surface when said casing is attached to the camera, and said solid state image pick-up element operates to produce picture signal elements in response to said object image;
(c) a readout control circuit coupled to said solid state image pick-up element for reading out a picture signal of prescribed form including said picture signal elements from said solid state image pick-up element; and
(d) a picture signal output terminal on said casing, said picture signal output terminal being coupled to said readout control circuit to provide said picture signal.

Abstract
A removably attachable electronic image pick-up device for use with a single lens reflex camera, includes a casing which is shaped to fit in a receptacle on the camera body, which receptacle is otherwise used to seat a replaceable optical finder to display an object image. The device also includes a solid state image sensor arranged within the casing to produce photosignals which are processed by a control circuit to a prescribed form of picture signal, and the picture signal is then supplied to an outlet connector. Accordingly, when a display device or a video tape recorder is connected to the outlet connector, the object image can be displayed on the display device, or the image can be recorded on the video tape recorder.
