  • Publication number: 20220292814
    Abstract: An image processing apparatus applies a learning process to a learning model using training data generated from first original images obtained by capturing a subject of inspection. The apparatus then performs, using the learned learning model, deduction processing on input data generated from a second original image obtained by capturing a subject of inspection. The training data is generated using a plurality of partial images from each of the first original images, and the deduction process uses a partial image of the second original image as the input data. The detection rate of an abnormal portion having a small size included in images of the subject of inspection is thereby improved.

    Abstract: A stereoscopic image display apparatus including: a light source unit; a light guide plate having an incidence surface and an emission surface; and a liquid-crystal panel which spatially modulates light. The light source unit emits the light so that the light is incident on the incidence surface in the first and second directions for the right and left eyes of a viewer, which are different from each other and each is inclined at a predetermined angle in the emission surface with respect to a reference direction perpendicular to an alignment direction of the right and left eyes of the viewer. Also, the light emitted from the emission surface of the light guide plate is in a direction which is determined according to the propagation direction of the incident light and in which a component in the alignment direction, included in the propagation direction, is maintained.
