    Abstract: Cooking system comprising a cooking area (1) with actuators (2) which are adjustable to change relevant parameters determining the cooking process of a food.

The processor (5) is associated with a memory device (7) storing typical cooking programs consisting each of a different combination of process parameters. The processor (5) is responsive to the incoming data to select the most suitable among the stored cooking programs, whereby it compares the parameters thereof with the corresponding information from the camera (3) to control the actuators (2) with respective error signals.
