Abstract: A method for identifying stored products in household storage devices. A set of images of a stored product of the storage device is captured, and the stored product is identified by evaluating image data of the set of images by a standard identification algorithm. The standard identification algorithm has been trained by way of a standard set of images captured with a standard configuration. Before the standard identification algorithm is used, a data characteristic of the image data is adapted to a standard data characteristic of the standard set of images by way of an adaptation algorithm that is at least partially trained based on a configuration of the household storage device. The method is particularly applicable for domestic food handling appliances such as refrigerators and cooking appliances and also extractor hoods.

Abstract: An economical household appliance device, in particular a household refrigerator device, includes at least one storage space and at least one food inspection or monitoring device for determining at least one food parameter of at least one item of food in the storage space by spectral analysis.
