[0025] figure 1 It is a flow chart of a method for enlarging a display frame by an input device according to an embodiment of the present invention. see figure 1 . A method for enlarging a display screen with an input device, suitable for enlarging a display screen of a computer device, comprising the following steps:

[0026] First, in step S101, the input device receives a notification command from the computer device. In practice, the input device is, for example, a mouse, a keyboard or a computer graphics tablet. This embodiment does not limit the aspect of the input device. For example, the human interface device class (Human Interface Device Class, HID Class) specification is adopted between the computer device and the peripheral products such as the input device, so that the computer device can distinguish the function and identity of each peripheral product such as the input device. Of course, the computer device can also customize its own instructions to notify t...

[0053] image 3 It is a functional block diagram of an input device capable of providing enlarged display images according to another embodiment of the present invention. see image 3 . An input device 1 capable of enlarging a display screen is suitable for enlarging a display screen of a computer device 9 , and includes a control unit 10 , an input operation unit 12 and a connection interface 14 .

[0054] The control unit 10 is coupled between the input operation unit 12 and the connection interface 14 . In practice, the control unit 10 is, for example, a central processing unit (CPU) or a microprocessor (MCU), etc., and is used to perform signal calculation and processing in the input device 1 . Wherein, the control unit 10 determines whether an operating system of the computer device 9 provides a system magnifying glass when the connection interface 14 is connected to the computer device 9 . This embodiment does not limit the aspect of the control unit 10 .

Abstract

The invention relates to an input device and a method for the input device to execute amplification of display images. The method for the input device to execute amplification of display images is applicable to amplification of the display images of a computer device and includes that the input device receives a notification instruction of the computer device, wherein the notification instruction indicates whether an operation system of the computer device provides a system amplification lens; when the operation system support use of the system amplification lens, the input device outputs a first amplification instruction to the computer device according to press of a functional key so that the computer device starts the system amplification lens provided by the operation system according to the first amplification instruction to amplify the display images; when the operation system does not support use of the system amplification lens, the input device outputs a second amplification instruction provided by the input device to the computer device according to press of the functional key, so that the computer device amplifies the display images according to the second amplification instruction.

Description

technical field [0001] The invention relates to an input device, in particular to an input device of a computer device and a method for enlarging a display screen thereof. Background technique [0002] Information products are currently developing towards multi-functional, exquisite and thin. In order to display more detailed and beautiful pictures, the display screens of information products are usually set in a higher resolution display mode, so that all The icons and fonts on the above display screen become smaller, so it will be inconvenient for users who have poor vision such as myopia, presbyopia or amblyopia, or need to browse and observe the icons and fonts on the display screen in detail Displays the picture of the screen. However, the operating systems of some existing information products already provide a system magnifying glass function, which can magnify the images viewed by users on the display screen. Contents of the invention [0003] The present inventi...
