Computer camera field of vision automatic switching device

摘要

A computer camera field of vision automatic switching device consisting of a computer monitor equipped with a camera that has a minimum of one roller ball switch installed in it, the signal output pin of which is connected to the input terminal of an image processor integrated circuit for capturing the control signal based on the position of the roller ball in the roller ball switch. After the image processor integrated circuit receives the changed signal normal status, the signal is transferred via the universal serial bus to a personal computer, where an image processing program determines the control signal value and verifies that the computer camera is at the rotated angle, the image processing program controlling image rotation based the determined angle of the computer camera lens and the quantity of roller ball switches. As such, whatever the interval of rotation, 90 degrees or 180 degrees, the field of vision is always displayed on the monitor in the current straight ahead position, without requiring the manual selection of numerous vertical or horizontal rotation command items, thereby achieving automatic field of vision switching and providing user convenience.
