DISPLAY APPARATUS, CONTROL METHOD, AND STORAGE MEDIUM

A display apparatus includes a display that displays an image captured by an imaging unit that captures an image of a view behind a moving object, a half mirror that reflects the view behind the moving object and disposed on an anterior surface of the display, one or more memories storing instructions, and one or more processors executing the instructions to switch a state between a mirror surface display state where a reflection image on the half mirror is displayed and an image display state where the image is displayed on the display and perform adjustment so that a viewing angle of the image displayed on the display and a viewing angle reflected by the half mirror are approximately the same as each other while switching the state between the mirror surface display state and the image display state.
