Abstract

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.

Claims

1. A computer camera field of vision automatic switching device in which the signals of a computer camera are transferred to the PC through an image processor IC via USB, enabling the display of the field of vision image on the monitor, the features of which are:

The said computer camera has a minimum of one roller ball switch installed in it and, furthermore, the signal output pin of the said roller ball switch is connected to the control pin of the said image processor IC;

The roller ball of the said roller ball switch when straight ahead is situated at the top extremity;

at the rotation of the said computer camera, a minimum of one said roller ball becomes situated at the said signal output pin position and, furthermore, is in a state of contact, changing the signal normal status of the said image processor IC control pin, the PC program controlling image rotation such that it is the at same rotated angle as the said computer camera, enabling the image to be automatically rotated to the straight-ahead position on the monitor.

2. As mentioned in claim 1 of the computer camera field of vision automatic switching device of the invention herein, two said roller ball switches are installed in the said computer camera and, furthermore, at the straight-ahead position of the said computer camera, the said two roller ball switches each inclined at a suitable angle apart such that the said roller balls are both situated at the top extremities of the said roller ball switches and separated from the said signal output pin such that signal normal status at the two said control pins of the said image processor IC remain unchanged, enabling the display of the image in the straight-ahead position on the monitor.

3. As mentioned in claim 2 of the computer camera field of vision automatic switching device of the invention herein, the said computer camera causes the said two roller ball switches to rotate 90 degrees to the right or 90 degrees in the opposite direction, the said two roller ball switches inclined at a suitable angle apart such that the said roller balls respectively descend to the top extremity and the bottom extremity of the said roller ball switches and, furthermore, the said roller balls contact the said signal output pins, thereby providing for changing the signal normal status of the said image processor IC control pins and enabling the PC program to control image rotation automatically such that it is at the same rotated angle as the said computer camera.

4. As mentioned in claim 2 of the computer camera field of vision automatic switching device of the invention herein, the said computer camera causes the said two roller ball switches to turn around 180 degrees such that the each of the said two roller balls descent to the bottom extremities of the said roller ball switches and, furthermore, both contact the said signal output pins, thereby providing for changing the signal normal status at the said two control pins of the said image processor IC and enabling the PC program to control image rotation automatically such that it is at the same rotated angle as the said computer camera.
