preview class for the camera object, which is a Surfaceholder object, set by the Setpreviewdisplay (Surfaceholder) method. Call the Startpreview () method to begin a preview of the camera object. The Takepicture () method is called to take a picture, where the image data is captured by the Camera.picturecallback () callback. When the shot is complete, you need to call the Stoppreview () method to

First, the camera working principleIn the previous article we talked about the composition of the camera module, working principle, as a kind of understanding. Let's analyze how the camera works from the register angle. How to read the camera spec (use key parameters for driver tuning, take GT2005 as an example).The sp

GLSurfaceView is a class in OpenGL and can also be used to preview Camera. It is unique in previewing Camera. Where is the uniqueness? When Surfaceview is powerless and hard to solve, GLSurfaceView can only be used. It can truly separate the data and display of Camera, for example, Camera only enables preview and does

Google has output TextureView from Android4.0. Why? This is to make up for Surfaceview's shortcomings. On the other hand, it is also to balance GlSurfaceView. Of course, this is my speculation. The relationships between TextureView, Surfaceview, SurfaceTexture, and GLSurfaceView will be analyzed after the artist launches GLSurfaceview preview Camera. This article describes how to preview Camera with Texture
