Abstract:
1. An image processing apparatus, comprising: a display module for displaying a digital image; a control module, connected to the display module for controlling the display module and conducting image processing; and a five-direction scroll wheel module, connected to the control module for being operated to generate at least five control signals for controlling the control module, the scroll wheel module further comprising: wherein the scroll wheel can be pressed vertically towards the base, so that a bottom portion of the frame touches and thereby triggers the first touch switch on the base; and when a predetermined force is applied to the scroll wheel towards either of two sides thereof, the sliding rails tilt downwards towards a direction in which the force is applied so as to cause a corresponding one of the protrusions formed on the frame to touch and thereby trigger a corresponding one of the two second touch switches on the base.
