Abstract: [Problem] To evaluate objective cell groups by estimating a mixing ratio of objective cell group without affecting treatment itself and its production process when the objective cell groups include plural kinds of cell groups having different attributes, and to provide an image analysis system and a culture management system capable of accurately perform a quality control and a production control with low cost. [Solution] The cell quality evaluation system 1 detects a feature amount in each cell easily analyzable from images, and estimates a mixing ratio of each of plural kinds of cell groups included in the objective cell groups based on a distribution of the detected feature amount and pre-recorded information of the feature amount. As the feature amount, the embodiment uses a migration speed of each cell, easily distinguishable by analyzing tracking of each cell from plural images in time series.

Abstract: The sanitary management system S includes a plurality of portable communication terminal devices 10, a manager terminal device 20 and a server device 40. The server device 40: (1) extracts two or more feature values related to the color of each pixel constituting a culture medium image; (2) executes statistical analysis based on distribution of pixels of the culture medium image by using a coordinate system prescribed by the extracted two or more feature values of each pixel, and calculates a linear function prescribing relation of the two or more feature values in each pixel; and (3) detects the colonies in the culture medium image based on the calculated linear function and counts the number of colonies.

Abstract: The sanitary management system extracts food produced or inspected using a work line including one or more production process or inspection process as a specimen, and registers culture medium information obtained by a portable communication terminal device before and after culturing the extracted specimen to a server device in correspondence with work line related information related to the work line including information of sanitary management of the work line from which the specimen is extracted.
