Embodiment 1

[0023] figure 1 It is a schematic flowchart of a method for enabling an HDR function on a smart terminal provided in Embodiment 1 of the present invention. The method can be executed by a device for enabling the HDR function on the smart terminal. The device can be realized by software and / or hardware, and be built in an intelligent terminal with HDR function. For example, a smart terminal may be an electronic device such as a smart phone, a tablet computer, or a personal digital assistant. see figure 1 The method for enabling the HDR function on the smart terminal provided in this embodiment specifically includes the following steps:

[0024] Step S110, acquiring the image captured by the camera through the camera;

[0025] Step S120, identifying whether the image satisfies the preset strong contrast condition;

[0026] Step S130, if the condition of strong contrast is satisfied, the HDR function of the camera is turned on.

[0027] At present, after starting the camera...

Embodiment 2

[0037] figure 2 It is a schematic flowchart of a method for enabling an HDR function on a smart terminal provided in Embodiment 2 of the present invention. In this embodiment, on the basis of the first embodiment above, the step of "identifying whether the image satisfies the preset strong contrast condition" is further optimized. see figure 2 The method for enabling the HDR function on the smart terminal provided in this embodiment specifically includes the following steps:

[0038] Step S210, acquiring the image captured by the camera through the camera;

[0039] Step S220, divide the image into multiple block images according to preset division rules;

[0040] Step S230, calculating the brightness value of each block image;

[0041] Step S240, according to the calculation result, identify whether the image satisfies the preset strong contrast condition;

[0042] Step S250, if the condition of strong contrast is satisfied, the HDR function of the camera is turned on. ...

Embodiment 3

[0055] Figure 3A It is a schematic flowchart of a method for enabling an HDR function on a smart terminal provided in Embodiment 3 of the present invention. This embodiment provides a preferred implementation solution based on all the foregoing embodiments. Referring to FIG. 3, the method for enabling the HDR function on the smart terminal provided in this embodiment specifically includes the following steps:

[0056] Step S310, acquiring an image captured by the camera through the camera.

[0057] In the embodiment of the present invention, the image captured by the camera through the camera is: the camera captures the raw data of the current scene, and the YUV or RGB obtained after the raw data is processed by the built-in ISP (image signal processing, image data processing) chip format image. This image will be displayed in a viewfinder presented on the terminal screen.

[0058] If the obtained image is an image in RGB format, each pixel in the image is composed of thr...

Abstract

The embodiment of the invention discloses a method and a device for opening an HDR (high-dynamic range) function on an intelligent terminal. The method comprises the steps of acquiring an image captured by a camera through a camera head; identifying whether the image meets a preset contrast ratio intensification condition or not; and opening the HDR function of the camera if the image meets the preset contrast ratio intensification condition. According to the technical scheme provided by the embodiment of the invention, opening of the high-dynamic range function can be controlled in an intelligent mode, and shot images with excellent image quality can be acquired without manual operations of a user.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a method and a device for enabling a high dynamic range (HDR) function on a smart terminal. Background technique [0002] Currently, cameras on smart terminals are generally provided with an HDR (High-Dynamic Range, high dynamic range) function. If the user manually activates this function, when the camera is turned on to take a photo, the camera will continuously take multiple photos under underexposure, normal exposure and overexposure conditions, and then combine these photos to obtain an HDR image. For HDR images, the details of both the highlights and shadows are relatively clear, which can better reflect the visual effects in the real environment. [0003] However, the opening of the HDR function often requires the user to manually open it, and many users do not know the function of this function, so this function is often left idle. Conte...
