Problems solved by technology

When the text to be scanned is small, you often see a large piece of text in the preview image, which makes it impossible to accurately scan the desired content. At this time, you need to zoom in on the focal length to obtain a larger picture and more accurate recognition content, but Due to hardware limitations such as the limited focal length of the camera of the smart watch, even if the maximum focal length is set, it is still impossible to obtain the desired content range, which affects the user experience

Embodiment Construction

[0013] The present invention will be further described below. It should be noted that this embodiment takes the technical solution as the premise, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0014] This embodiment provides a method for a smart watch to realize camera preview magnification, and the specific process is as follows:

[0015] S1. Obtain the Camera object by calling the start camera method open of the Android camera Camera development API, and obtain the maximum focal length through the getMaxZoom method of the Camera internal class Parameter, thereby setting the maximum focal length of the Camera camera;

[0016] S2. Obtain the View object that renders the camera preview interface, and realize the substantial enlargement of the View by setting the scaleX and scaleY of the View property animation ObjectAnimator. The magnification of scaleX and sc...

Abstract

The invention discloses a method and equipment for realizing camera preview amplification of a smart watch, on the basis of original maximum focal length limitation, secondary amplification of a drawing range of SurfaceView or TextureView for rendering a preview picture is realized by software means through scaeX and scaeY of attribute animations ObjectAnimation, the attribute animations are View changes in a real sense, not only are amplification on preview, but also are amplification on TextureView. Data processing can also be amplified according to the proportion, and the method can be well matched with small-size screen equipment such as an intelligent watch and the like to obtain large previews when the small-size screen equipment wants to obtain the large previews.

Description

technical field [0001] The invention relates to the technical field of smart watches, in particular to a method and device for realizing camera preview magnification for smart watches. Background technique [0002] With the popularity of smart watches, more and more users use smart watches, and at the same time, wearable devices such as smart watches are more and more widely used, such as OCR recognition and learning by scanning text, words, words, etc. through cameras. When the text to be scanned is small, the preview image often sees a large piece of text, which makes it impossible to accurately scan the desired content. At this time, it is necessary to enlarge the focal length to obtain a larger picture and more accurate identification content, but Due to hardware limitations such as the limited focal length of the camera of the smart watch, even if the maximum focal length is set, it is still impossible to obtain the real desired content range, which affects the user exp...
