Abstract: A data analysis system executes data analysis in response to a data analysis request from a plurality of data analysis request sources and includes a filtering unit, a data analysis unit, a data storage unit, and a filter control unit. The filtering unit filters input data by applying a predetermined filter to the input data. The data analysis unit analyzes the filtered input data. The data storage unit stores the input data and result data as data that has been analyzed. The filter control unit records application history of a filter applied in response to the data analysis request, and refers to the filter application history for a new data analysis request to select a filter suitable for data analysis to be executed, and transfers the selected filter to the filtering unit.

Abstract: When a recording medium (5) is inserted or taken out, an LED of an insert opening is made to blink so that a user will not make an error or forget to take the medium. Moreover, prior to an image data read process, a storage device having a storage capacity not smaller than a predetermine storage capacity, is detected and a service is terminated. This avoids a long-time read process. Furthermore, in a date acquisition process, if the image data has no imaging date/time information, file creation date/time information or file update date/time information, associated with the image data is acquired and surely printed on a print object (7).
