Problems solved by technology

The acquisition of the application window handle must apply to the display system, so the back and forth interaction between the camera application layer and the camera service layer is delayed for a long time, resulting in a slow preview display
It takes a certain amount of time for the camera application layer to create an application window, and the time is not stable, so the startup time fluctuates, and even a short black screen on the display and other bad user experience

Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] The method and system for quickly starting the camera preview provided by the smart device and the smart device provided by the present invention can establish a local window by the camera service layer for quick preview before previewing the application window, and obtain the application window handle sent by the camera application layer at the camera service layer Then switch the window to the application window for display.

[0046] Please refer to image 3 with Figure 4 , are respectively a flow chart and a process schematic diagram of a method for quickly starting a camera preview on a smart device according to the first embodiment of the present invention. Such as image 3 with Figure 4 As shown, the method for quickly starting c...

Abstract

The invention relates to a method and a system for quickly starting the camera previewing of intelligent equipment and the intelligent equipment. The method at least comprises an application window creation step, a previewing data acquisition step and an application window previewing step, and also comprises: steps of a local window creation step that a camera service layer transmits a local window creation instruction to a display system after receiving a camera connection instruction, and receives a local window handle from the display system; and a local window previewing step that the camera service layer calls a created local window to display acquired previewing data after detecting that the local window handle is acquired. The camera service layer directly interacts with the display system to establish the local window for previewing in an early stage before an application window is created for previewing, and the local window is smoothly switched to the application window for display when an application window handle created by a camera application layer is acquired, so that frequent interaction during starting is avoided, and the aim of quick and stable display previewing is fulfilled.

Description

technical field [0001] The present invention relates to the technical field of smart devices, and more specifically, relates to a method, a system and a smart device for quickly starting a camera preview on a smart device. Background technique [0002] Most of the current smart devices have a camera function. Most camera modules on smart devices designed with layered software architecture adopt C / S (client / server) mode in software implementation, and camera applications and services run in different processes. Such a system provides a conventional process to operate the camera hardware and the display system. When starting, the camera service layer generally needs to bridge the camera application layer to interact with the display system. [0003] Please refer to figure 1 with 2 , which is a flowchart of a method for starting a camera preview by a smart device in the prior art and a schematic diagram of the process. Such as figure 1 with figure 2 As shown, the camera ...
