Core Image

Core Image (core image) is one of the frameworks to constitute Mac OS X, and the filter of the image is component processing it and API using プログラマブルシェーダー of GPU. I let a CPU act for a calculation in the environment that does not have プログラマブルシェーダー.

Core Image was introduced in Mac OS X v10.4.

Each filter is comprised of a plug in form called Image Unit (image unit), and a system becomes available in total if I incorporate it once.

Because a value of each pixel is not an integer and is handled in single precision floating point number, a very accurate operation result is provided.

GLSL standardized in OpenGL standard is used for シェーディング language [¹].
