Abstract
An image processing apparatus for applying film grain effects on an image of received image data includes a generating unit configured to generate, on the basis of pixel values randomly read from grain data including a plurality of pixel values, a basic grain image having a certain size larger than the grain data; a resizing unit configured to resize the basic grain image generated by the generating unit to have the same size as the received image data; and a combining unit configured to combine the basic grain image resized by the resizing unit with the received image data.
Claims13
An image processing apparatus comprising:
- a generating unit configured to generate, on the basis of pixel values randomly read from grain data including a plurality of pixel values, a basic grain image having a certain size larger than the grain data;
- a resizing unit configured to resize the basic grain image generated by the generating unit;
- and
- a combining unit configured to combine the basic grain image resized by the resizing unit with received image data.
A method for controlling an image processing apparatus, comprising:
- a generating step of generating, on the basis of pixel values randomly read from grain data including a plurality of pixel values, a basic grain image having a certain size larger than the grain data;
- a resizing step of resizing the basic grain image generated in the generating step;
- and
- a combining step of combining the basic grain image resized in the resizing step with received image data.
