Embodiment 1

[0027] figure 1 A flowchart showing a photographing method provided by an embodiment of the present invention, such as figure 1 As shown, the method is executed by an electronic device, and the electronic device is provided with a camera. The method provided in this embodiment includes the following steps.

[0028] Step S1, when the image sensor collects an image, detect the brightness of the surrounding environment of the camera.

[0029] Step S2, when it is detected that the luminance value is less than a preset luminance threshold, control the image sensor to use an adding mode (adding mode) to capture an image, and the adding mode is used to increase the sensitivity of the image.

[0030] Specifically, an image sensor is an important part of a digital camera. According to different components, it can be divided into two categories: charge coupled device (Charge Coupled Device, abbreviation: CCD) and metal oxide semiconductor device (Complementary Metal-Oxide Semiconduct...

Embodiment 2

[0035] figure 2 Show the flowchart of the photographing method provided by the next embodiment of the present invention, such as figure 2 As shown, the imaging method in this embodiment includes the following steps.

[0036] Step S1, when the image sensor collects an image, detect the brightness of the surrounding environment of the camera.

[0037] Step S201, when it is detected that the brightness value is lower than a preset brightness threshold, send a request for whether to enable the overlay mode.

[0038] Step S202, when receiving a confirmation message of enabling the superimposition mode in response to the request, controlling the image sensor to use the superimposition mode to acquire images.

[0039] Wherein, the overlay mode is used to increase the sensitivity of the image.

[0040] When the image sensor collects images, the brightness sensor can detect the brightness of the surrounding environment of the camera. When the brightness value is greater than or e...

Embodiment 3

[0044] image 3 Show the flowchart of the photographing method provided by the next embodiment of the present invention, such as image 3 As shown, the imaging method in this embodiment includes the following steps.

[0045] Step S1, when the image sensor collects an image, detect the brightness of the surrounding environment of the camera.

[0046] In step S200, the image sensor uses the collected image as an original image, and the original image includes charges induced by a plurality of pixels. Step S201, when it is detected that the brightness value is lower than a preset brightness threshold, send a request for whether to enable the overlay mode.

[0047] Step S2021, when receiving the confirmation message of turning on the overlay mode in response to the request, add the charges induced by the pixels in adjacent x rows and x columns in the original image, and induce the added pixels The charge of is taken as a pixel, where x is a natural number and ≥2. Step S2022, t...

Abstract

The embodiment of the invention relates a photograph method, device and electronic equipment, belonging to technical field of image. The method comprises the steps of detecting luminance of the surrounding environment of the camera when the image sensor collects images; controlling the image sensor to adopt overlapping mode to collect images when the luminance is smaller than the preset threshold value. The overlapping mode is used for improving sensitivity of the image. When the illumination intensity is low, the shorter exposure time and smaller gain can be used to take images with normal illumination, which avoids that the photos are unclear due to too loud image noise caused by long-time exposure and amplification of gain.

Description

technical field [0001] The present invention relates to the field of image technology, in particular to a photographing method, device and electronic equipment. Background technique [0002] At present, mobile terminal devices such as mobile phones and cameras are usually equipped with cameras, and users can take pictures through the cameras. However, in low light conditions, the image captured by the camera is low in brightness, resulting in blurry photos. [0003] In the prior art, the brightness of the photo can be controlled by adjusting the exposure time and gain of the image sensor in the camera. The longer the exposure time and the higher the gain, the higher the brightness of the photo. [0004] Based on this, the inventors of the present invention found that in the existing method, in order to improve the brightness of the photo, the exposure time is increased and the gain is increased in the case of dark light. Blurred, and photo noise is high, seriously affectin...
