Apparatus and method for processing image, and computer-readable storage medium

摘要

An apparatus and a method for processing an image. The method includes: increasing contrast of an input image to generate a first image; adding a mask having a pattern showing an image effect, to the first image to generate a second image; and adjusting a range of pixel values of the second image to generate a resultant image.

1. A method of processing an image, comprising:
capturing the image; receiving a user selection of an image effect; increasing the contrast of the captured image according to a first look-up table (LUT) to generate a first image, wherein the first LUT is configured to adjust pixel values in a 1-1st brightness range of low brightness values to a minimum brightness value of the pixel brightness values, increase contrast of pixel values in a 1-2nd brightness range of intermediate brightness values, and adjust pixel values in a 1-3rd brightness range corresponding to upper brightness values to a maximum brightness value of the pixel values; adding a mask having a pattern showing the selected image effect to the first image to generate a second image; removing the effect from at least part of the second image according to a second LUT, wherein the second LUT is configured to adjust pixel values in a 2-1st brightness range of the second image corresponding to a low pixel value range to a minimum value of the pixel values and reduce pixel values in a 2-2nd range of the second image to generate a resultant image; and displaying the resultant image as a live-view image.
