Prior to capturing images, a camera is turned on and a first image depicting a first optical pattern is captured and a first optical pattern is decoded within the first image. The camera is switched to a first mode corresponding to a first power consumption level. It is ascertained whether the camera has been in the first mode for a first period of time and, if so, the camera is switched to a second mode corresponding to a second power consumption level that is less than the first power consumption level. A code scanning request is detected while the camera is in the second mode and, in response to detecting that the code scanning request has been received while the camera is in the second mode, a second image depicting a second optical pattern is captured with the camera.

Camera start optimization for optical pattern decoding

An optical pattern in a real scene is decoded after acquiring a video stream using a camera of a mobile device, wherein the video stream comprises preview images of the real scene and the optical pattern is in the real scene. A viewport for a screen of the mobile device is defined. The viewport is overlayed on an application window. The video stream is presented in the viewport, wherein at least a portion of the optical pattern is depicted in the viewport. The optical pattern is decoded in one or more images of the real scene acquired by the camera.
