Problems solved by technology

For the filmed film, in the prior art, due to single-lens shooting, the effect of the film is often fixed. Although it can be set in the early stage or edited in the later stage, the processing is also on the whole. Make adjustments to the finished film; and if the user wants to highlight the subject in the captured image, such as a portrait or a lotus, it is difficult to achieve the desired effect through pre- or post-editing

Abstract

The present invention provides a photographing device, method and mobile terminal. The first image of the subject is captured under normal exposure conditions through the first camera module, and the subject is captured under dark light conditions through the second camera module. The second image, wherein the brightness of the subject is greater than the brightness of the background, and the actual distance between the subject and the background is greater than or equal to a preset distance; the image of the subject is separated from the first image to obtain the object image, the object image An image of the subject is included; the subject image and the second image are superimposed to form a composite image. Through the implementation of the present invention, the object image collected under normal exposure has a clear contrast with the lightness and darkness under dark light conditions, and the superimposition of the two can significantly highlight the position of the subject in the composite image, and the film is real and natural.

Description

Technical field [0001] The present invention relates to the field of photographing and photography, and more specifically, to a photographing device, method and mobile terminal. Background technique [0002] Camera photography is playing an increasingly important role in people's lives. This is a very convenient way to record life. Users only need to gently press the shooting button to save the current shooting moment. For the filmed film, in the prior art, since the single-lens filming is mostly, the filming effect is often fixed. Although it can be set in the early stage or retouched in the later stage, the processing performed is also on the whole. Adjust the film; and if the user wants to highlight the subject in the captured image, such as a portrait or a lotus flower, it will be difficult to achieve the desired effect through pre- or post-retouching. Summary of the invention [0003] The technical problem to be solved by the present invention is how to avoid the problem tha...
