ABSTRACT:
An image pick-up apparatus (1) for picking up a plurality of sub-images and combining them so as to form a composite image, including a correction unit (5) for correcting brightness values of the composite image. The correction unit (5) includes a selection unit (6) for selecting bright and dark parts from the sub-images. There is also provided an arithmetic unit (10) for deriving a gain correction factor from the bright parts and an offset correction term from the dark parts. The correction unit (5) also includes a multiplier unit (8) and an adder unit (9) for multiplying signal levels of a sub-image signal by the gain correction factor and for adding the offset correction term thereto. The image pick-up apparatus is used in an X-ray examination apparatus (20) for picking up an optical image on the exit window (32) of an X-ray image intensifier (24) and for supplying an electronic image signal for a high-resolution composite image so that image information in a medical X-ray image with small details can be suitably reproduced.
