Abstract: A method of switching between multiple operating systems of a computer system includes the following steps. Firstly, the computer system is in an environment of a first operating system. Then, a system management interrupt is triggered to allow the computer system to enter a system management mode, and a controlling authority of the computer system is transferred from the first operating system to a basic input output system. Then, a backup of a first environmental parameter of the first operating system is created. If the second environmental parameter is not included in the computer system, a second operating system is loaded in a normal mode. On the other hand, if the second environmental parameter is included in the computer system, the second operating system is booted according to the second environmental parameter.

The method is for enlarging a specific zone at the touch control screen and for the user to edit or selection at the enlarged zone. The method includes steps of: determining whether a plurality of first touch points stay at the touch control screen over a predetermined time; enlarging a partial zone image for showing an enlarged zone on the touch control screen; providing a second touch point on the enlarged zone for generating a corresponding position signal; and scaling the position signal, generating a converted signal and inputting the converted signal to a control module.

Abstract: A display control method of a touch control screen and an electronic device applying the same are provided. According to the method, small user interfaces are magnified, and the user selects a target user interface according to a magnified zone. The method includes steps of: forming a touch boundary according to a position signal of a touch point; determining whether the touch boundary collides with a user interface; executing an image magnifying action according to the touch boundary and displaying the magnified zone on the touch control screen if the touch boundary collides with the user interface at the touch control screen; vanishing the touch point on the touch control screen after moving the touch point to a target user interface to execute a corresponding function of the target user interface via a control application module.

Abstract: A method for image auto-selection and a computer system thereof are provided. In the method, a characteristic value of each of the images is compared with the predetermined characteristic value stored in a characteristic value database, and the images with less difference between the characteristic value and the predefined characteristic values are selected automatically. As a result, the image selection can become more objectively, and the efficiency of image selection can be improved due to the reduction of the manual selection time.

Abstract: A computer system and a method for calculating straightness of facial are provided. In the method, an image is processed to obtain a facial area and eyes locations. The facial area is divided into two sub-areas. Then, each of the sub-area and the corresponding symmetric image thereof are coupled together to form two reference images. Finally, the characteristic values of the facial area and two of the reference images are used for calculating the straightness of the facial area based on the principle of facial symmetry. As a result, the judgment on the straightness of the facial in an image can be more correct and objective, and the situation of taking an image with a tilted angle of facial can be avoided.

Abstract: A method for changing a booting source when a first operating system is being executed is disclosed. The method is utilized in a computer system having a first storage device storing the first operating system and a second storage device storing a second operating system. The method includes: receiving a signal from the second storage device; detecting whether the second storage device is a target device; setting the second storage device as a booting device; rebooting; and executing the second operating system from the second storage device.

Abstract: A method of relocating a notification icon corresponding to a notification area displayed on a computer screen includes providing a display window displayed on the screen, hooking messages inputted to or outputted from the notification area, obtaining icon information and function information of the notification icon according to the hooked messages, hiding the notification icon, displaying the notification icon on the display window according to the icon information, and then providing functions of the notification icon according to the function information.
