Problems solved by technology

Therefore, whether it is a professional shooting device or the above-mentioned digital shooting device, it can only be used for light painting shooting in a dark shooting environment; There are a large number of other bright spots polluting the image, and it is not possible to obtain a clear light painting trace
[0005] Therefore, the existing shooting device can only perform light painting photography in a dark shooting environment (such as night), and cannot perform light painting photography in a bright shooting environment (such as daytime), and cannot meet the user's needs for light painting creation anytime and anywhere. demand, poor user experience

[0033] see figure 1 , the first embodiment of the shooting method of the present invention is proposed, and the shooting method includes the following steps:

[0034] Step S101: Obtain and store the features of the auxiliary target. Before shooting starts, the shooting device can directly obtain ready-made feature data from the outside, or prompt the user to select the auxiliary target on the preview interface, and extract the feature data of the auxiliary target selected by the user and save it. storage.

[0035] It is better for the auxiliary target to have obvious features, so that the shooting device can track the auxiliary target according to the characteristic parameters in the subsequent shooting process. The auxiliary target can be a stylus, a human hand, or a combination of both. The stylus can be any object that can emit light.

[0036] Step S102: After the shooting starts, the camera continuously collects images

[0052] see figure 2 , the second embodiment of the shooting method of the present invention is proposed, and the shooting method includes the following steps:

[0053] Step S201: Obtain and store the features of light-painted bright spots

[0054] Before shooting starts, the shooting device can directly obtain ready-made feature data from the outside, or prompt the user to select the light-painting bright spot on the preview interface, and extract and store the feature data of the light-painting bright spot selected by the user. The characteristics of the light-painted bright spot include the brightness, area, outline, diameter, etc. of the bright spot. The light-painting bright spot is the bright spot formed by the light-painting pen emitting light.

[0055] In this embodiment, the features of the light-painted bright spots are stored in advance, so that the light-painted bright spots can be directly tracked later.

[0056] Step S202: After shooting starts, the camera con...

Abstract

The invention discloses a shooting method and a shooting device. The shooting method comprises the steps of continuously acquiring images, reading the acquired images and searching the image read at present according to a pre-stored characteristic to identify a light painting region in the image read at present, extracting the light painting region and superposing the light painting region on a foundation image in a corresponding position to perform image synthesis, and taking the synthesized image as the foundation image for next time of image synthesis. As only the light painting region is superposed and synthesized and other light spot regions in the image are not in the synthesized image to cause pollution on the synthesized image, a clear light painting trajectory can be recorded in the final synthesized image, light painting shooting in bright shooting environment is realized, the application occasions of the light painting shooting are expanded, the requirement of a user on light painting creation anytime anywhere is met and the experience of the user is enhanced.

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] In recent years, a shooting mode of light painting photography has emerged, and users can use light painting photography for artistic creation. The light painting photography refers to a shooting mode that utilizes long-time exposure to create special images through changes in light sources during the exposure process. Due to the need for long-time exposure, corresponding photosensitive hardware is required to support it, and the photosensitive hardware that can support long-time exposure is relatively expensive. It is impossible for the shooting device to be equipped with such expensive hardware equipment. [0003] In order to realize light painting photography on a digital camera device, a solution is proposed in the prior art, in which image data is collected continuously through a...
