A lossless image compression method comprises: a pre-processing step for dividing a target image into pixel blocks of a specific size; a step for generating a modulation block by performing differential pulse code modulation (DPCM) on the pixel blocks; a step for generating a Golomb-Rice (GR) block by performing variable Golomb-Rice encoding based on the modulation block; a step for generating a code sequence of variable length by detecting the presence or absence of a code for the modulation block and the type of the code, and checking whether or not size data about each pixel of the modulation block corresponds to a specific value and removing a code bit indicating a code of any corresponding pixel from the code sequence; and a step for generating compression image data (including a divisor of the determined variable Golomb-Rice encoding and the code sequence of variable length) based on the Golomb-Rice block and the code sequence.

The present invention relates to a method and system for calculating a consumed amount of food ingredients. The method according to the present invention comprises the steps of: (a) obtaining a consumed food amount of a food searched for in a consumed food amount database in order to be calculated; (b) obtaining an ingredient proportion ratio of the food searched for in the ingredient proportion ratio database, and calculating an ingredient proportion ratio consumed amount using the obtained consumed food amount; (c) determining whether or not the ingredients in the calculated results for the ingredient proportion ratio consumed amount are raw ingredients; (d) accumulating weight data on the ingredients determined to be raw ingredients among the ingredients in the calculated results for the ingredient proportion ratio consumed amount; (e) repeatedly performing steps (b) to (d) on ingredients, which are not raw ingredients, until all of the ingredients in the calculated results for the ingredient proportion ratio consumed amount become raw ingredients; and (f) if all the ingredients in the calculated results for the ingredient proportion ratio consumed amount are raw ingredients, obtaining a consumed amount of food ingredient on the searched food by adding the accumulated weight data to each food ingredient. According to the present invention, all components of a mixed food are converted into food ingredients ultimately, so that more accurate consumed food amount data may be conveniently calculated.
