Image forming apparatus, method for controlling image forming apparatus, and storage medium storing computer program

A processing apparatus comprising:

• a camera which captures an object in front of the processing apparatus;
• a display which displays a screen;
• one or more controllers including one or more processors, the one or more controllers configured to:
• acquire a face image of a first user and a face image of a second user, is the first and second users being within a first distance from the processing apparatus, the face images being captured by the camera;
• receive an authentication result of user authentication performed based on the acquired face images of the first and second users;
• and
• cause the display to display a screen corresponding to the user who has been authenticated and reached a second distance if one of the authenticated first and second users has reached the second distance from the processing apparatus, the second distance being shorter than the first distance,
• wherein when the first user reaches the second distance before the second user, the screen corresponding to the first user is displayed even when the second user has been authenticated before the first user and when the second user reaches the second distance before the first user, the screen corresponding to the second user is displayed even when the first user has been authenticated before the second user.

A method for controlling a processing apparatus including a camera which captures an object in front of the processing apparatus, and a display which displays a screen, the method comprising:

• acquiring a face image of a first user and a face image of a second user, the first and second users being within a first distance from the processing apparatus, the face images being captured by the camera;
• authenticating the first user based on the acquired face image of the first user and authenticating the second user based on the acquired face image of the second user;
• and
• causing the display to display a screen corresponding to the user who has been authenticated and reached a second distance if one of the authenticated first and second users has reached the second distance from the processing apparatus, the second distance being shorter than the first distance,
• wherein when the first user reaches the second distance before the second user, the screen corresponding to the first user is displayed even when the second user has been authenticated before the first user and when the second user reaches the second distance before the first user, the screen corresponding to the second user is displayed even when the first user has been authenticated before the second user.
