Abstract: A method of providing information includes acquiring allergy information related to a user from a first server, the allergy information including information indicating a level of an allergic reaction of the user to each ingredient, generating, based on the menu information and the allergy information, a personalized menu arranged for the user according to the allergy information, the menu information including information indicating one or more ingredients contained in each dish and an amount of each ingredient, and transmitting the personalized menu to the information terminal. In the generating of the personalized menu, when the level of the allergic reaction of an ingredient in the menu information is equal to or lager that a criterion value, the ingredient is determined as an allergy ingredient that causes allergy. The personalized menu includes one or more dishes, in each of which the allergy ingredient that causes allergy is reduced.

Abstract: In a converting method relating to picture luminance according to one aspect of the present disclosure, the picture luminance is formed by luminance values in a first luminance range. In this method, a first luminance signal that indicates code values obtained by quantizing the luminance value of the picture is obtained, code values, which are associated with the code values indicated by the obtained first luminance signal by quantization for a second luminance range different in a maximum value from the first luminance range are determined as converted code values, and the first luminance signal is converted into a second luminance signal indicating the converted code values. As a result, the converting method is further improved.

Abstract: To provide an encoding method for reducing deterioration in encoding efficiency when encoding a video/an image by selecting one operation mode out of a number of operation modes. The encoding method includes: extracting one or more features from one or more reconstructed pixel groups; categorizing the one or more reconstructed pixel groups using the extracted one or more features and a first machine learning model; and performing an encoding process on a current block of image samples included in a current picture using a parameter set corresponding to a result of the categorizing, the parameter set being one of a plurality of predefined parameter sets.
