Embodiment Construction

[0019] The present invention is aimed at a camera device with a viewfinder, and can better meet the user's shooting needs by identifying and enlarging the part of the viewfinder image where the user wishes to obtain details.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] This embodiment is the process of recognizing and enlarging the face in the viewfinder image, such as figure 2 As shown, the process steps are:

[0022] Step 201 : Obtain the to-be-processed area of ​​the face through face recognition.

[0023] In this embodiment, there are two persons A and B in the viewfinder image, and the sizes of their faces in the viewfinder image are inconsistent. like figure 1 As shown, set ③ as the coordinate origin of the viewfinder plane, the direction toward ① is Y, (Y>0), and the direction toward ④ is X, (X>0).

[0024] The face is captured by the camera system, and the active appearance (AAM) fac...

Abstract

The invention discloses a method for processing images in a viewfinder. The method is applied to a camera system with a viewfinder. The camera system captures an image and displays it through the viewfinder. The method includes: identifying the image in the viewfinder The area to be processed, the area to be processed is a rectangular area, and the aspect ratio of the rectangular area is not equal to the aspect ratio of the set size; the length or width of the area to be processed is the larger one unchanged, adjust the size of the other to obtain the adjusted area to be processed, the aspect ratio of the adjusted area to be processed is equal to the aspect ratio of the set size; enlarge the adjusted area to be processed to the The set size is then displayed through the viewfinder. Through the present invention, when the area to be processed is a rectangular area and the aspect ratio does not meet the set condition, image distortion in the enlarging process is avoided without modifying the enlarging scheme. The invention also discloses a device for processing images in the viewfinder.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a method and device for processing images in a viewfinder. Background technique [0002] With the development of computer network and consumer electronics technology, more and more camera products such as portable digital cameras and digital video cameras have entered people's lives, making people's lives more colorful. Although the camera effects of portable camera products are getting better and better, due to the impact of portable applications, the viewfinders of these camera products are relatively small in size and have a low resolution, which makes it difficult for people to view the full image on the viewfinder. Resolve details. [0003] With the development of the current image recognition technology, people use the image recognition technology to solve the above problems. However, these technologies are mainly used in autofocus and exposure control, so that expos...
