Abstract

The present invention provides a generation method of an image bokeh effect and an image acquisition device. The generation method of the image bokeh effect comprises the following steps: obtaining image frames including a current input pixel, and performing fuzzification processing of the image frames by respectively employing a first image fuzzy filter and a second image fuzzy filter to generate a plurality of first blurred images and second blurred images with respect to different fuzzy degrees; calculating the distance between the current input pixel and a focusing plane to obtain a current distance; respectively selecting a first current blurred image and a second current blurred image from the first blurred images and the second blurred images according to the current distance, and combining the first current blurred pixel of the first current blurred image and the second current blurred pixel of the second current blurred image according to the current distance to generate a current output pixel.

Description

technical field [0001] The invention relates to a method for generating image bokeh effects and an image acquisition device. Background technique [0002] In photography, the so-called "bokeh" (Bokeh) means that in photographic imaging with a shallow depth of field, the images falling outside the depth of field will gradually produce a loose and blurred effect to highlight the subject in the captured image, or Enhance the artistic sense of images. [0003] In general, camera lenses are limited in the amount of bokeh they can produce. To obtain a better bokeh effect, the following important conditions usually need to be met at the same time: large aperture and long focal length. In other words, in order to achieve the bokeh effect, it is necessary to rely on a large-aperture lens to enhance the blurring of distant objects, so that the clearly imaged subject can stand out from the background. However, large-aperture lenses are bulky and expensive, and cannot be equipped wit...
