Problems solved by technology

Once selected improperly, it may make the pattern that is expected to be clear, because the object being photographed does not fall into the target depth of field and become blurred

Embodiment Construction

[0027] The following uses simple geometric optics to introduce the imaging principle of the camera and its impact on in-focus and out-of-focus objects.

[0028] Please refer to Figure 1A , which shows the imaging of the in-focus object 20 and the bokeh produced by an out-of-focus light source. The so-called bokeh is the part of the image that is out of focus.

[0029] The focal length of the photographing lens 25 is f, and the focus object 20 is on the first side of the photographing lens 25 at twice the focal length (2f). It can be deduced from a simple optical theory that a real image 22 of the same size will be produced at a position on the second side of the shooting lens 25 at twice the focal length (2f). In other words, the clear pattern of the in-focus object 20 can be obtained by moving the optical sensor of the camera to the position of the real image 22 on the second side of the shooting lens.

[0030] Assuming that the focal length of the photographing lens 25 is ...

Abstract

The invention discloses an image editing method and an image processing apparatus which can be used for editing an original image. The original image at least comprises a clear pattern and a fuzzy pattern which correspond respectively to a focusing object and a defocusing object. The image editing method comprises the steps of obtaining a defocusing object distance from the defocusing object to a lens; conducting defuzzy processing for the fuzzy pattern to obtain a processed pattern based on the defocusing object distance and an optical parameter; and forming a processed image based on the processed pattern and the clear pattern.

Description

technical field [0001] The present invention relates to an image processing method and device, in particular to a method and device for processing an original image captured by a digital camera. Background technique [0002] Due to the rapid development of image capture technology, digital cameras have become an indispensable electronic device in daily life. In order to be able to easily operate digital cameras, commonly used consumer cameras (point-and-shoot cameras or cameras equipped with mobile phones) have a deep field of depth (field of depth), so they can easily shoot clear images. [0003] Professional cameras (such as SLR cameras) have the characteristics of large aperture and shallow depth of field, which require users with high shooting skills to operate. However, the image captured by the SLR camera has a high sense of hierarchy, and the consumer camera cannot capture the shooting effect similar to that of a professional camera. [0004] However, as users know,...
