Abstract:
A scanning type image pick-up apparatus comprising:an image pick-up camera including (1) a first optical system for condensing a light wave, (ii) a second optical system for changing an optical path of the light wave condensed by the first optical system, (iii) a charge storage type image pick-up element for receiving the light wave the optical path of which is changed by the second optical system, and performing optical/electrical conversion on the light wave, thereby to obtain a view image, (iv) a first rotating mechanism for rotating the second optical system to scan the light wave over the image pick-up element, and (v) a second rotating mechanism for rotating a rotation axis of the first rotating mechanism around a rotation axis of the first optical system, thereby to change an angle at which the light wave is scanned; camera scanning means for causing the image pick-up camera to linearly scan a view range in a reference direction and shifting a scanning axis along which the image pick-up camera linearly scans the view range such that the scanning axis is perpendicular to the reference direction, thereby to perform two-dimensional scanning; angle speed detecting means for detecting scanning angle speeds in the reference direction and a direction perpendicular thereto: and a controller for controlling driving of the first and second rotating mechanisms of the image pick-up camera based on the scanning angle speeds detected by the angle detecting means, such that the second optical system causes the light wave to perform reverse scanning in association with the two-directional scanning of the camera scanning means.
