Problems solved by technology

[0004] Due to the long duration of shooting star trails, during the shooting of star trails, there are usually unexpected interferences. For example, if a car passes by the shooting scene, the ambient light of the shooting scene suddenly becomes brighter due to the car lights. At this time, it will collect Images with abnormal backgrounds, which will affect the quality of the final composite image and reduce the shooting effect

[0032] see figure 1 , the first embodiment of the shooting method of the present invention is proposed, and the shooting method includes the following steps:

[0033] Step S101: start shooting

[0034] Step S102: Detect whether the ambient light changes abruptly

[0035] During the shooting process, the shooting device detects the ambient light in real time or every preset time, preferably through an ambient light sensor, which can be a light metering module on the camera or a light sensor of the shooting device such as a mobile phone itself . The scene where the ambient light changes suddenly, such as when a car passes by the shooting scene, the light of the car causes the shooting scene to suddenly become brighter.

[0036] Specifically, the shooting device detects whether the brightness of the ambient light exceeds a preset threshold or a statistical value, wherein the statistical value refers to a normal range value of the ambient light in the current shooting environme...

[0046] see figure 2 , the second embodiment of the shooting method of the present invention is proposed, and the shooting method includes the following steps:

[0047] Step S201: start shooting

[0048] Step S202: Detect whether the ambient light changes abruptly

[0049] When a sudden change in the ambient light is detected, go to step S203; otherwise, continue normal shooting and continue to detect the ambient light. .

[0050] Step S203: Do not use the currently collected image

[0051] When the photographing device detects a sudden change in the ambient light, it may discard (delete) the currently captured image, and not use the image for image synthesis. Alternatively, the currently collected images can also be stored without being synthesized, and the user decides whether to delete them after the shooting is completed.

[0052] Step S204: Detect whether the ambient light returns to normal

[0053] When it is detected that the ambient light returns to normal, go to...

Abstract

The invention discloses a shooting method and a shooting device. The shooting method comprises the following steps: detecting whether ambient light is suddenly changed in the shooting process, if so, pausing shooting or not using the currently acquired image; when the ambient light returns to normal, recovering the shooting or returning to use an subsequently acquired image, thereby avoiding acquiring the image with abnormal background or removing the image with abnormal background, the image with abnormal background can be prevented from synthesizing to the final synthesis image to influence the picture quality, the interference of the suddenly changed ambient light on the shooting process is eliminated, and the shooting effect is improved.

Description

technical field [0001] The present invention relates to the technical field of photographing, in particular to a photographing method and a photographing device. Background technique [0002] Star trail shooting refers to the shooting mode in which the shooting device shoots the trajectories of stars through long-term continuous exposure. When shooting star trails, the exposure time usually takes 20 to 60 minutes, and the photosensitive hardware that can support long exposure is relatively expensive. Only professional camera devices such as SLR cameras are equipped with the aforementioned photosensitive hardware. For digital shooting devices such as digital It is impossible for cameras, mobile phones, tablet computers, etc. to be equipped with such expensive photosensitive hardware. [0003] The Chinese patent with application number 201410112654.3 discloses a shooting method of a mobile terminal, which uses a camera to capture an image every preset time, and performs image...
