Embodiment Construction

[0043] The following uses simple geometric optics to introduce the imaging principle of the camera and its influence on the focused object.

[0044] Please refer to figure 2 , which shows the imaging principle of the camera. The focal length of the photographing lens 25 is F, and the focused object 20 is outside 2 times the focal length (2F) of the first side of the photographing lens 25 . Obviously, a smaller real image 22 will be generated between the 1x focal length (F) and the 2x focal length (2F) of the second side of the photographing lens 25 . In other words, a clear image of the focused 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.

[0045] Assuming that the focal length of the photographing lens 25 is F, the distance between the focused object 20 and the photographing lens 25 is Dn, and the distance between the real image 22 and the photographing lens 25 is In, then...

Abstract

The invention relates to an image editing method for editing an original image, and the original image at least comprises a first object and a second object. The image editing method comprises the following steps: obtaining a first distance between the first object and a lens; obtaining a second distance between the second object and the lens; obtaining a fuzzy matrix system according to the first distance and an optics parameter; obtaining a first fuzzy matrix from the fuzzy matrix system according to the second distance; and forming a fuzzy second object after performing a fuzzy processing action on the second object according to the first fuzzy matrix, wherein the first object and the fuzzy second object form a simulation image.

Description

technical field [0001] The invention is an image editing method, and in particular relates to a method of converting an original image into a simulated image conforming to the optical characteristics of a lens by utilizing the distance between each object in the original image and the shooting lens. 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 cann...
