Abstract
A method and an apparatus for adjusting output images are provided. In the method, a target area is selected from the original frame received by an image receiving device and an image capturing device is controlled to capture the image within the target area. Hence, users can change angles to view images within different target areas without rotating the lens of the video device. In addition, the image resolution is adjusted automatically according to the screen resolution of the image receiving device or the resolution corresponding to the network bandwidth. Therefore, the defects in the prior art that mechanical operation is easily damaged and the manufacturing cost is high are eliminated. The purpose of effectively enhancing image resolution is also achieved.
