Is the head-up camera a computer camera?

No.

The head-up lens places the angle of view at eye level with the subject's eyes, allowing the audience to feel that they are in the scene and observe the subject's face at close range, while the subject or subject is photographed. The subject's head is level with the camera. The position of the lens aperture determines where to shoot more accurately than the bottom of the camera body. You can align the base of your camera with your subject's shoulder so that the aperture of your lens is level with your subject's eyes.
