ABSTRACT:
In an image pickup apparatus according to the present invention, a rotary scanning mirror (2) is rotated to sense the image of an original (10) by a linear image sensor (4), which in turn outputs picture signals to be stored in a frame memory (5), so that the image of the original (10) is displayed on a display unit (6) on the basis of the stored picture signals. A light pen (9) specifies a scanned range of the image displayed on the display unit (6) and a controller (8) indicates rotation angles of the rotary scanning mirror (2) on the basis of position signals from the light pen (9) to specify the scanned range while varying the step size of the rotary scanning mirror (2) thereby to vary resolution. Thus, a noted region in the original (10) can be easily image-sensed in high resolution.
