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

The simple project we implemented in the previous article, and now we continue to add features for this camera. First, in Camera, we can perform simple control over the Camera. When we need to configure more functions, we need to use the Parameters class under Camera. The Parameters class encapsulates most of the funct

Build a Camera Application Some developers may want to customize the Camera user interface in their applications, or provide some special functions. Creating a custom Activity requires more code than using Intent, but it can provide a better user experience. Follow these steps to create a customized Camera interface: 1. Check and access

Camera physical architecture Generally, camera consists of two parts: lens and sensor IC. Some sensor ICPs integrate DSPs, while others do not integrate, but they also need external DSP processing. In terms of subdivision, the camera device consists of the following parts:Lens Lens is the lens. Generally, the lens structure of

Imagine a lot of tourists shooting Eiffel Tower at different angles at the same time, how to describe the process in a mathematical way. The first problem to be solved is positioning, or the choice of coordinates, the Eiffel Tower has only one, if according to Warp, latitude to depict, its coordinates is only certain, but the visitor obviously does not relate to this point, he (she) only according to own preference chooses the angle and the position, therefore, the object (scenery) has the objec
