Abstract

The invention discloses a device comprising a processing device and a method for color correction of an image in the processing device, the method comprising: obtaining an image; determining the Laplacian matrix of the image; obtaining the a first region of an image, the first region indicating a portion of the image to be color corrected; obtaining a second region of the image; obtaining a first recolored image based on the second region; determining a first corrected region of a first corrected image with the Lass matrix and the first recolored image; and obtaining and outputting a corrected image based on the first corrected region of the first corrected image.

Description

[0001] The present disclosure relates to a method and apparatus for correcting an image in a processing device. Background technique [0002] A very well-established process in studio photography is to photograph objects in front of the background that are easily separated from the foreground. This background is usually blue or green, so it is called blue screen photography or green screen photography. This setup enables automatic subsequent removal of the background using so-called chroma keying, which is why it is largely considered the industry standard. However, a side effect of this process is that light spills from the background onto the object, which leads to incorrect coloring of the final image. [0003] Various procedures called "overflow correction" have been proposed to alleviate this problem, see eg US 6,553,140, ​​US 7,280,117, US 7,692,664, US 8,081,821 and CN 101764913. [0004] However, these methods do not provide images corrected to a satisfactory level. ...
