Improving a depth image subject to a shadow effect

A processor device configured to produce a final image that comprises pixels juxtaposed in a substrate presenting thickness and producing an image that possesses thickness so that each pixel produces a shadowing effect on its neighboring pixels, said processor device comprising:

• an acquisition unit for acquiring a target image;
• and
• a determination unit configured to use the target image to determine a production setpoint suitable for being used by an image production device to produce said final image;
• wherein the determination unit is configured to perform operation comprising:
• modeling the image production device by means of a transfer function transforming a production setpoint into a corresponding predicted image;
• and
• by inverting at least a portion of the transfer function, determining an improved production setpoint suitable for use as a production setpoint by the production device in order to produce said final image in such a manner as to correct at least in part the shadowing effect in the final image.
