Embodiment 1

[0025] Such as figure 1 As shown, a kind of method of improving backlight photographing effect of the present embodiment comprises the following steps:

[0026] S101, the light perception value difference range of non-backlight is preset in the processor;

[0027] S102, the front camera monitors the surrounding ambient light value of the device and sends it to the processor;

[0028] S103, the rear camera monitors the ambient light sensitivity value 2 on the back of the device and sends it to the processor;

[0029] S104, the processor calculates the difference after receiving light-sensing value 1 and light-sensing value 2 and compares it with the backlight preset value;

[0030] S105, if the light sensitivity value difference exceeds the backlight preset value range, the processor sends a signal to the camera controller;

[0031] S106, the camera controller turns on the flash to shoot.

[0032] As an improvement of the technical solution of the present invention, the fro...

Embodiment 2

[0035] Such as figure 2 Shown: This embodiment is a device for improving the effect of taking photos against the light according to the light sensitivity value. The device includes a front camera and a rear camera for monitoring the light sensitivity value of the front and back of the device; One and the photosensitive value two and calculate its difference and then compare it with the processor of the preset value; the camera controller for controlling the camera flash light switch; the front camera and the rear camera are respectively electrically connected to the processor, and the processing The device is electrically connected to the camera controller.

[0036] As an improvement of the technical solution of the present invention, the preset value is the difference range of the light sensitivity value of non-backlight.

Abstract

The invention provides a method and a device for improving the effect of photographing against the light. The method and the device adopt the principle that light sensation data are obtained according to preview images received via camera bodies; and when a judging result shows that the photographing condition of the user is against the light, and a flashlight is turned on automatically to perform a supplemental lighting effect. Two sensors are required according to the method. When the camera comprising the camera bodies is turned on for photographing, environmental light intensities acquired according to the front camera body and the back camera body respectively are read, and are compared to obtain brightness difference, and whether the photographing condition of the camera is against the light or not is judged by analyzing the brightness difference; and if the judging result shows that the photographing condition of the camera is against the light, the flashlight of the back camera body is turned on automatically to perform the supplemental lighting effect and further improve the photographing effect under the condition.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for improving the effect of backlight photographing. Background technique [0002] In today's society, mobile devices emerge in an endless stream, especially mobile phones, tablet computers and cameras. People's requirements for spiritual life are increasing day by day. Whether it is traveling or daily life, people will use mobile phones or cameras to record life anytime and anywhere. [0003] When taking pictures under backlighting conditions, since the environment is still relatively bright, the flash will not be turned on, so the exposure time is relatively short, and the backlit scenes (such as human faces) will be very dark and difficult to see clearly. Contents of the invention [0004] In view of this, the present invention provides a method and device for improving the effect of backlight photography. The principle of the present invention is to obtain t...
