Problems solved by technology

[0011] Compared with offline processing, online composition guidance is more practical, because post-processing is time-consuming and labor-intensive and will inevitably reduce image quality (such as reducing resolution), and currently there is no shooting device on the market that has the function of suggesting composition

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] The implementation process of the present invention is as attached figure 1 As shown, the specific steps include:

[0026] 1) Input picture;

[0027] 2) Perform subject detection on the picture to find out the position of the subject;

[0028] 3) Detect the location of one or more gaze points;

[0029] 4) Determine whether the position of the gaze point coincides with the position of the subject, if it coincides, it is considered that there is no background interference, and perform step 6); otherwise, it is considered that there is background interference, and then perform step 5);

[0030] 5) Give suggestions for reconstructing the image, if accepted, reconstruct the image, remove interference, and go to step 3), if not accepted, go to step 6);

[0031] 6) Output pictures.

[0032] Among them, it mainly includes three parts: subject position detection, in...

Abstract

The invention provides a method for improving the picture composition effect of a digital camera. The method comprises the following steps of: detecting a main body position in a picture by using a main body detection module, detecting a fixation point position in the picture through a fixation point detection module by using a bottom-to-top visual attention model, then judging whether background interference exists by analyzing the relative relationship between the main body position and the fixation point position, and if so, giving a suggestion for reconstructing the picture. Based on a simple interactive calibration main body object, the method can be used for automatically detecting the interference and suggesting reconstructing the picture; and proved by experiments, the adopted method can be operated quickly and can be used for effectively improving the picture composition effect.

Description

technical field [0001] The invention relates to computer image processing, in particular to a method for improving image effects of digital cameras. Background technique [0002] With the development of science and technology and the improvement of people's living standards, digital cameras, mobile phone cameras and other shooting devices are becoming more and more popular. Using these devices to record life anytime and anywhere has gradually become a living habit of people. In the past ten years, the hardware development of the camera has made great progress. On the one hand, the imaging components of the camera are becoming more and more sophisticated, and the imaging quality is getting better and better. On the other hand, the chip processing capability of the camera has also improved rapidly. The existing image processing technology has been solidified on the camera to further improve the imaging capability of the camera. For example, Canon’s new camera has solidified th...
