Patent attributes
An operation determination device that determines a change in the facing direction of a user's face as a contact-free operation on a display image includes an image acquisition unit that acquires a captured image that is captured of the user's face and an image processing unit that performs image processing on the captured image and detects the direction of the user's face. The image processing unit includes a first processing unit that detects a portion of the user's face in the captured image and a second processing unit that determines the direction of the user's face in relation to a display surface that displays the display image, on the basis of the portion of the user's face detected in the captured image. The first processing unit includes hardware that executes specific detection processes, and the second processing unit includes one or more processors executing software that execute processes according to output from the first processing unit.
