Patent ID: 7170547

Claim:
A stereoscopic image-taking lens apparatus which is attachable to an image-taking apparatus provided with an image-pickup element, comprising: an optical system which forms right and left optical paths for guiding light from an object, which has entered said right and left optical paths, to said image-pickup element; a shutter which is changed over so as to guide the lights which have respectively entered the right and left optical paths alternately to said image-pickup element; a control circuit which changes over said shutter so that lights from said right and left optical paths are guided alternately to said image-pickup element at every predetermined time so as to allow said optical system to form parallax images in time sequence on said image-pickup element; and a communication circuit which performs communications with said image-taking apparatus; wherein the control circuit sends a signal for inhibiting an image-taking operation in which the charge-storage time of said image-pickup element is longer than the predetermined time for changing over said shutter to the image-taking apparatus via said communication circuit.
