A conventional design is to linearly map the hand position to the cursor position, however, the control resolution is very low due to the large difference in resolution between the captured image and the display screen Yes, for example, small movements of the user's hand can cause the cursor to move a lot on the display screen, so it is not easy for the user to precisely control the cursor

Embodiment Construction
[0028] Certain terms are used throughout the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.
[0029] The main concept of the invention is to use ...

The invention provides a method for determining control output in control domain and a control apparatus thereof. The control apparatus has a receiving circuit and a processing circuit. The receiving circuit is arranged for obtaining the control input from an input domain, wherein the control input includes a previous input value and a current input value. The processing circuit dynamically adjusts a control resolution setting, and converts the control input of the input domain into the control output in the control domain according to the control resolution setting. The control resolution setting for the current input value is determined according to at least the previous input value, and the current output value is identical to the previous output value when the current input value and the previous input value are generated in response to a same user input. The method for determining control output in control domain and control apparatus thereof greatly improves a user's operation experience and lowers calculation amount.
Description
technical field [0001] The present invention relates to high-resolution control by using low-resolution input, and more particularly to a method and a control device for determining a control output in a control domain by using a variable control resolution technique to convert the input domain The control input of (for example, image-based object tracking domain) is transformed into the control output of the control domain. Background technique [0002] Remote controls have been commonly used to control electronic devices, such as televisions. Although the remote control makes the control of the electronic device more convenient, however, when the back of the electronic device becomes more complicated than before, the number of buttons of the remote control will also increase in order to properly control the electronic device, so remember to assign It is not easy to assign all functions to individual buttons. [0003] To solve this problem, the prior art has proposed seve...
