Image synthesis method and system based on front camera and rear camera

Abstract

The invention is applied to the technical field of communications, and provides an image synthesis method and system based on a front camera and a rear camera. The method comprises the steps that a front-shot image and a rear-shot image are obtained through the front camera and the rear camera respectively; a character image area is recognized and extracted from the front-shot image; the character image area is synthesized into the rear-shot image to generate target images. Therefore, image synthesis of the front camera and the rear camera can be achieved on the basis of hardware of an existing terminal device, the content of the synthesized image is more accurate and conforms to needs of a user better, and therefore interestingness and user experience of shooting operation are improved; meanwhile, more cost is saved. Better yet, before the images are synthesized, image parameters of the character image area can be adjusted and processed, the adjusted and processed character image area is closer to the quality of the rear-shot image, and therefore the image of the front camera and the image of the rear camera are fused together more naturally, and the quality of the synthesized image is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image synthesis method and system based on front and rear cameras. Background technique [0002] On the basis of the rapid development of hardware in mobile phones and other terminals, the function of previewing or shooting with the front and rear cameras can already be realized, which mainly outputs the image data of the front and rear cameras to the screen for preview, and what you see is what you get saved as an image. When the existing front and rear cameras are turned on for preview or shooting at the same time, the image generated by the front camera and the image generated by the rear camera are directly superimposed to synthesize the image. Therefore, in the synthesized image, there is a clear boundary between the images of the front and rear cameras, and the user can clearly feel that the two images are superimposed together. [0003] In summary, ther...

Problems solved by technology

When the existing front and rear cameras are turned on for preview or shooting at the same time, the image generated by the front camera and the image generated by the rear camera are directly superimposed to synthesize the image. Therefore, in the synthesized image, there is a clear boundary between the images of the front and rear cameras, and the user can clearly feel that the two images are superimposed together, and the effect shown is rough and stiff, which cannot meet the expected satisfactory effect of the user

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
