Abstract
A cathode-ray tube image recording device for recording images on a photosensitive thermal development recording medium which may have a reduced sensitivity due to time deterioration. An image of a density wedge is exposed and developed then sensed to determine the sensitivity of the recording medium. The sensing operation produces a density identification step number which is used to set one or both of the brightness and light emission time of the cathode-ray tube in accordance with a predetermined characteristic curve or function. A switchable resistor circuit or read-only memory may be used for applying the characteristic function.
