PURPOSE:To attain high resolution and high-speed image pickup by rotating a linear light sensor around the optical axis of an image pickup lens to obtain a 2-dimensional visual field. CONSTITUTION:A detection head 10 formed by incorporating a linear optical sensor 3b and an image pickup lens 2 is rotated by psi-degrees for N times by a scanning circuit 5 and a moving device 4 at each end of electric scanning of the linear light sensor 3b. The operation is repeated till the relation of psi.N=180 deg. exists to pick up the circular 2-dimensional visual field 1 on an object face and the output of the light sensor 3b obtained by the turning scanning is inputted to a processing section 8, where it is processed. Thus, the 2-dimensional visual field is obtained without being affected by its image pick up range and the image pickup device with high resolution and high speed is obtained.
