Problems solved by technology

In this way, not only will there be deviations in the judgment of whether to start the HDR camera mode, but also the startup process is cumbersome.
[0005] The HDR shooting mode can also be activated according to the scene judgment. The general scene judgment method is mainly based on the analysis of the brightness histogram of the preview image, so as to determine whether it belongs to the backlight scene. However, due to the complexity of the backlight scene itself, the simple brightness histogram judgment method There will be large misjudgments and omissions

[0025] figure 1 It is a flow chart of the method for taking photos of backlit scenes provided by the first embodiment of the present invention. This embodiment can be applied to the processing of backlit scenes when a photographing device takes photos. equipment to perform.

[0026] see figure 1 , the photo shooting method of the backlight scene comprises:

[0027] S11, detecting real-time environmental parameters of photo shooting.

[0028] It can be understood that when a digital camera or mobile terminal is used to take photos, the environment where the digital camera or mobile terminal is located can be characterized by real-time environmental parameters. The real-time environment parameters may include: time information, time zone information, global positioning position information, weather condition information, terminal orientation information, and the like. The real-time environment parameters are parameter data that can be collected by the digital camera or the m...

[0037] figure 2 It is a flow chart of scene recognition in the method for taking photos of backlit scenes provided by the second embodiment of the present invention; this embodiment is based on the above-mentioned embodiments of the present invention, and further provides a method for scene recognition in the method of taking photos of backlit scenes a technical solution. In this technical solution, performing backlight scene identification according to the real-time environment parameters includes: determining the confidence level of being in a backlight scene according to the values ​​of the real-time environment parameters; and determining whether the current scene is in a backlight scene according to the confidence level.

[0038] see figure 2 , performing backlight scene recognition according to the real-time environment parameters includes:

[0039] S21. According to the value of the real-time environment parameter, determine the confidence level of being currently i...

[0046] image 3 It is a flow chart of determining confidence in scene recognition provided by the third embodiment of the present invention; this embodiment further provides a technical solution for determining confidence in scene recognition based on the above-mentioned embodiments of the present invention.

[0047] see image 3 , according to the value of the real-time environment parameter, determining the confidence level of the current backlight scene includes:

[0048] S31. Determine a positioning position confidence level according to a matching result between the global positioning position information and the time zone information.

[0049] If the global positioning position information cannot be obtained for a period of time, it is judged that it is more likely to be an indoor environment, and a lower confidence level of the positioning position is given.

[0050] When the global positioning location information can be obtained, compare the geographic location info...

Abstract

The embodiment of the invention discloses a method and device for shooting a picture in a backlight scene. The method comprises the following steps of: detecting a real-time environmental parameter for picture shooting; performing identification of the backlight scene according to the real-time environmental parameter; and performing auxiliary shooting processing of the backlight scene according to the identification result. According to the method and device for shooting the picture in the backlight scene provided in the embodiment of the invention, the starting process of auxiliary processing of the backlight scene is simplified.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of smart terminals, and in particular to a method and device for taking photos of backlit scenes. Background technique [0002] With the popularization of digital cameras and various mobile terminals equipped with cameras, taking digital photos has become commonplace in people's lives. [0003] When taking digital photos, it is often encountered that the object to be photographed must be backlit. Photos taken in this situation often suffer from loss of detail in the highlights or shadows of the image. If a high dynamic range (High dynamic range, HDR) photographing mode is adopted, the above-mentioned problems can be well solved. [0004] However, in existing photographing devices, whether to start the HDR photographing mode usually requires human judgment and setting. That is to say, the user of the photographing device will manually activate the HDR photographing mode when he feels ...
