Embodiment Construction

[0045] In order to quickly generate a full depth image on a general consumer camera, the present invention synthesizes and simulates a full depth image by shooting two images with different focus distances. In order to improve the existing limitation of having to use a tripod for shooting, and avoid relying on manual and complicated image post-production, the present invention must perform geometric correction on the captured image so that two images with different focus distances can be correctly superimposed, and Only by correctly estimating the relatively clear areas of the two images can compensation be effectively performed. In order to make the content of the present invention clearer, the following examples are listed as examples in which the present invention can actually be implemented.

Abstract

Provided are a method and a device for producing a panoramic deep image. The method for producing the panoramic deep image comprises the steps: (1) shooting according to a main focus distance and a minor focus distance respectively to produce a main focus image and a minor focus image respectively, (2) diminishing the main focus image and the minor focus image respectively, (3) conducting geometric correction on the diminished main focus image and the diminished minor focus image to produce a corrected minor focus image, (4) dividing the main focus image and the corrected minor focus image into a plurality of blocks, (5) judging whether each block in the main focus image needs to be compensated by means of the corrected minor focus image, (6) producing a compensation block by means of an overlap block compensation method and a weight type differential consolidation method, and (7) compensating the main focus image by means of the compensation block to produce the panoramic deep image.

Description

technical field [0001] The present invention relates to an image processing method and device, in particular to a processing method and device for generating full depth images. Background technique [0002] Most of the existing methods for generating full-depth images use a combination of multiple images captured under various shooting conditions. The so-called photographic conditions are only composed of parameters such as aperture, shutter, and focal length. By changing one or more parameters in the photographic conditions, different images of the same scene are shot, and then these images are classified by the definition method. Combined into a clear image. [0003] The technique of using the above-mentioned various shooting conditions to synthesize a full-depth image must rely on a fixed image acquisition device for shooting. Generally speaking, users often use a stable tripod to fix the image acquisition device to ensure that there is no obvious geometric distortion a...
