Abstract: An article image data acquirer acquires article image data as a target of optical character recognition (OCR). An inference result data generator generates first inference result data and second inference result data by inputting the article image data as the target of the OCR into a trained model. An inference result data outputter outputs the first inference result data and the second inference result data. An image filter generator generates a first image filter based on the first inference result data and a second image filter based on the second inference result data. An image filter outputter outputs the first image filter and the second image filter.

Abstract: A training data acquirer acquires training data including article image data, image-filter-related data indicating a combination of a plurality of image filters used for image processing of the article image data and a value of a parameter for each of the plurality of image filters, and optical character recognition (OCR) score data indicating a score of character recognition output through OCR when image processing is performed on the article image data using the image filters based on the image-filter-related data. A trained model generator generates a trained model indicating a relationship between the article image data, the image-filter-related data, and the OCR score data through machine learning using the training data.

Abstract: A communication device and a data collection system that, when lower connection devices are connected to a communication device, improve efficiency of communication between the communication device and an upper connection device. There is an acquirer that acquires data from the lower connection devices, and a transmission setter that sets a transmission period, which is a time interval in which the data acquired by the acquirer from the lower connection devices is compiled and the compiled data is transmitted to the upper connection device as transmission data, to be equal to or longer than a communication period that is the longest among communication periods of the lower connection devices. Further, there is a transmitter that transmits the transmission data to the upper connection device with the transmission period that is set by the transmission setter.
