Camera, and image display apparatus including the same

A camera comprising:

• a first optical structure configured to refract and reflect a first input beam to output a second beam with a width smaller than a width of the first input beam;
• and
• a second optical structure configured to refract and reflect a second beam from the first optical structure to output a third beam with a width greater than the width of the second beam,
• wherein a ratio of the width of the second beam to the width of the first input beam is greater than 0.5 and smaller than 1.

An image display apparatus comprising:

• a case;
• a display;
• a camera disposed at a rear of the case;
• and
• a controller configured to control the display to display an image captured by the camera,
• wherein the camera comprises:
• a first optical structure configured to refract and reflect a first input beam to output a second beam with a width smaller than a width of the first input beam;
• and
• a second optical structure configured to refract and reflect the second beam from the first optical structure to output a third beam with a width greater than the width of the second beam,
• wherein the first optical structure comprises a first reflection surface configured to reflect the first input beam, and
• wherein a first angle between the first reflection surface and the second beam, a second angle between an orthogonal surface orthogonal to the first input beam and the first reflection surface, and a third angle between the rear surface of the rear case and the first reflection surface are each greater than 0° and smaller than 45°.
