Abstract: In a method for determining a target processing state of a cooking product to be treated using a cooking appliance, a set of images of the cooking product in different processing states is provided to a user, with measurement signatures being stored for the images. When the user selects one of the images, the cooking appliance assumes a corresponding one of the measurement signatures associated with the selected image as a target measurement signature.

Abstract: In a method for operating a cooking appliance, a cooking compartment is irradiated by light of different wavelength ranges. Light reflected in the cooking compartment is measured and measurement results of the light measurement are spectroscopically evaluated. Depending on a result of the spectroscopic evaluation, operation of the cooking appliance is adjusted.

Abstract: In a method for operating a household cooking appliance, a camera records a pixel-based image from a cooking chamber of the household cooking appliance. The image is evaluated with exclusion of brightness values of associated pixels thereof.

Abstract: In a method for operating a cooking appliance, a measurement profile is recorded of a light reflected by a food during a heat treatment cycle. A time instant of a turning point is determined from the measurement profile, and an action is triggered on the basis of the determined time instant of this turning point.

Abstract: In a method for treating food to be cooked in a household cooking appliance, a sensor measures a local distribution of a surface condition of the food to be cooked. A measure of deviation is calculated from the measured local distribution and multiple local power distributions that are known in advance in the region of the food to be cooked in correspondence with different sets of setting values of a unit for treating the food to be cooked. A unit for treating the food to be cooked is operated by using the set of setting values of the one of the power distributions for which the measure of deviation fulfills a predetermined criterion.
