Abstract
An electronic deviceincludes an image-capturing unit, a line-of-sight detector, and a controller. The controllerfunctions as a low-concentration heat map group estimatorand a high-concentration heat map estimator. The low-concentration heat map group estimatorcan estimate a low-concentration heat map group based on an image. The high-concentration heat map estimatorcan estimate a high-concentration heat map based on the image. The controllercalculates the degree of concentration of a subject based on the low-concentration heat map group, the high-concentration heat map, and a line of sight of the subject. The low-concentration heat map group estimatoris constructed using learning data obtained by machine learning the relationship between learning images and lines of sight for each load factor. The high-concentration heat map estimatoris constructed using learning data obtained by machine learning the relationship between learning images and lines of sight when the load has been removed or the load has been reduced.
