Abstract
An object of the present invention is to control the lens iris and shutter speed such that automatic light quantity adjustment is made of an object the image of which is to be picked up without being influenced by the ambient quantity of light. Another object of the present invention is to control the shutter speed of an image pickup camera to pick up the image of a target object during the rotation of a rotational stand without allowing the image to flow asynchronously. An image pickup camera 1 comprises a vertical position detector 12 and a horizontal position detector 13 for detecting the rotational position of the camera 1. Data 21 on control over the quantity of light for the detected positional information 20 is beforehand stored in a correction data storage 14. Correction data 21 for the position information 20 is delivered to the camera 1. A lens iris driver 10 subtracts the correction data 21 from the quantity of light from a lens 2 to produce a signal to automatically control the light quantity of the lens iris 11.
