1. An inference device for inferring image filters usable for image processing to be performed before performance of OCR on article image data that is data of an image of an article captured by an imaging component, the OCR being optical character recognition, the inference device comprising:
article image data acquiring circuitry to acquire the article image data as a target of the OCR;
inference result data generating circuitry to generate, by inputting the article image data as the target of the OCR into a trained model, inference result data indicating a combination of a plurality of image filters usable for image processing of the article image data as the target of the OCR and a value of a parameter for each of the plurality of image filters, the trained model being generated through machine learning using training data including (i) the article image data acquired in advance, (ii) 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 (iii) OCR score data indicating a score of character recognition output through the OCR when image processing is performed on the article image data using the image filters based on the image-filter-related data, the inference result data generating circuitry being to generate first inference result data as the inference result data and second inference result data as the inference result data different from the first inference result data; and
inference result data outputting circuitry to output the first inference result data and the second inference result data.
