To provide an infrared image pickup apparatus in which image drift can be corrected completely without requiring any cooler.

An infrared ray intercepting means intercepts external infrared rays and the drift component data of an image data picked up while intercepting external infrared rays by the infrared ray intercepting means is stored in a correction data memory 3. Drift component data of the image data picked up while opening the infrared ray intercepting means is stored in a correction data memory 4. The drift component data stored in both memories 3, 4 are then correlated and the drift component included in the image data is removed based on the correlation value.
