ABSTRACT:
An image processing apparatus capable of flexibly changing edge enhancement, blurring, and other image effect processing, wherein, in accordance with the execution of a program by a CPU, the CPU produces control signals to control an image processing circuit, read circuits in the image processing circuit read image data from a memory circuit by using a texture function, a write circuit writes the image data produced by subtraction by a subtraction circuit, multiplication with a coefficient by a multiplication circuit, and addition by an addition circuit to the memory circuit, and the image processing circuit performs processing relating to image effects such as α-blending, edge enhancement, and blurring on the basis of the control signals from the CPU.
