Passive optical mouse using image sensor with optional dual mode capability |
摘要 |
A passive optical mouse is provided. The mouse does not require an interrogating light source. Instead, the mouse includes a sensor array and lens assembly that captures ambient images from arbitrary sources. A comparison is made between successive images to determine movement of the mouse. The movement of the mouse causes a movement vector to be output, which is used to control movement of a cursor of a computer. In addition, the mouse is configured to provide dual mode operation wherein the mouse can also operate as a video camera. |
