Abstract:
An image input device for executing successive operations for picking up images comprising:an image pickup means for picking up an image of an object to obtain image data for the object for a certain number of pixels; alight-shuttering means for performing a light-shuttering operation to form a light-shuttered state relative to said image pickup means; a strobo-light emitting means for emitting strobo-light when an image of an object is picked up by said image pickup means; a first control means for controlling a second operation for picking up an image among successive operations for picking up images by said image pickup means at a timing when the image data obtained in a first operation for picking up an image among the successive operations for picking up images by said image pickup means is read out from said image pickup means, and also for controlling, after said second operation for picking up the image, the light shuttering operation by said light-shuttering means at a timing earlier than a timing when the image data obtained in said second operation for picking up the image is read out from said image pickup means; and a second control means for controlling an operation for emitting strobo-light by said strobo-light emitting means so that a time interval from starting of said second operation for picking up an image until second strobo-light is emitted is made shorter than a time interval from starting of said first operation for picking up an image until first strobo-light is emitted.
