 ### How to Implement
 
 * The APIs for AI text recognition are encapsulated in **CameraModel**. For details about the source code, see [Camera.ets](entry/src/main/ets/common/utils/Camera.ets).
-    * Camera module: encapsulates the APIs for initializing and releasing the camera.
-    * On the Index page, a click event triggers camera shooting. After the photo output stream is obtained, use @hms.ai.ocr.textRecognition to extract the text from the photo.
