Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] like figure 1 As shown, the method for removing screen shake in the embodiment of the present invention includes the following steps:
[0027] S1. Obtain the display range information of the image display control. The image display control uses integer coordinates to control the movement of the image; the display range information limits the display range of the control and is the boundary coordinates of the original control.
[0028] S2. Generate a first image display area according to the display range information of the image display control, and display the image to be displayed by the ...

The invention discloses a method for removing frame jitter and an image display control. The method comprises the following steps: acquiring display scope information of the image display control, wherein the image display control uses an integer coordinate to control movement of the image; generating a first image display area according to the display scope information of the image display control and displaying the image which needs to be displayed by electronic equipment in the first image display area, wherein the first image display area uses a floating point coordinate to control the movement of the image. According to the invention, when the image display control is moved at a variable speed, the movement of the first image display area can be more fluent from a visual aspect. In the prior art, the image display control generates the frame jitter during the variable speed movement. By using the method and the control of the invention, the above problem can be solved.
Description
technical field [0001] The invention relates to image processing, in particular to a method for removing image shake and an image display control. Background technique [0002] In the process of using the handleless control, in order to improve the development efficiency, all interface elements are inherited from the handleless control; then when the control has integer coordinates, the interface elements are developed based on integer coordinates. Therefore, the variable speed animation developed will produce shaking phenomenon; the variable speed animation includes when the current smart device drags the scroll bar or slides the screen with the hand in a certain direction, the effect of changing the acceleration of the screen (from fast to slow, and finally stops), and many more; [0003] For example: when the current screen movement is about to stop, first slide at a speed of 0.25 pixels / S for 1 second, then slide at 0.15 pixels / S for 1 second, and finally slide at 0.1 p...
