Abstract
Provided is an apparatus for processing image blurring configured to extract a sample image by calculating a blur generation area through scales of a horizontal length and a vertical length of an original image, read a pixel value corresponding to the blur generation area calculated from the original image and perform a bitwise operation on the sample image, and set, at a pixel of the sample image changed by the bitwise operation, a result value of the bitwise operation. In this case, the bitwise operation performed on the sample image includes applying the same blurring value on n pixel regions adjacent to a corresponding pixel of the sample image to reduce the time for removing image noise.
Claims12
An apparatus for processing image blurring, the apparatus comprising:
- a camera configured to capture an image;
- a memory in which a program for performing blurring processing on the image is stored;
- and
- a processor configured to execute the program stored in the memory,
- wherein the program, when executed by the processor, causes the processor to:
- determine a first scale factor for scaling a width of an original image;
- determine a second scale factor for scaling a height of the original image;
- generate a scaled sample image using the original image, the first scale factor, and the second scale factor, wherein the scaled sample image is smaller than the original image by a factor of (1/(the first scale factor)*(the second scale factor));
- read, from the original image, a plurality of pixel values corresponding to the scaled sample image;
- perform a bitwise operation on the plurality of pixel values read from the original image;
- identify one or more changed pixels of the scaled sample image whose values were changed as a result of the bitwise operation;
- and
- for the one or more changed pixels, set one or more corresponding pixel values according to the result of the bitwise operation.
A method of processing image blurring performed by an apparatus for processing image blurring, the method comprising:
- determining a first scale factor for scaling a width of an original image;
- determining a second scale factor for scaling a height of the original image;
- generating a scaled sample image using the original image, the first scale factor, and the second scale factor, wherein the scaled sample image is smaller than the original image by a factor of (1/(the first scale factor)*(the second scale factor));
- reading, from the original image, a plurality of pixel values corresponding to the scaled sample image;
- performing a bitwise operation on the plurality of pixel values read from the original image;
- identifying one or more changed pixels of the scaled sample image whose values were changed as a result of the bitwise operation;
- and
- for the one or more changed pixels, setting one or more corresponding pixel values according to the result of the bitwise operation.
