1. An image processing apparatus comprising: an acquisition unit configured to acquire image data including a first pixel and a second pixel adjacent to the first pixel, wherein a concentration of a first color component of the first pixel is deep and a concentration of the second color component of the first pixel is light, while a concentration of the first color component of the second pixel is light and a concentration of the second color component of the second pixel is deep; a process unit operative to perform a first process of increasing the concentration of the first color component of the second pixel and to perform a second process of increasing the concentration of second color component of the first pixel; a determination unit configured to determine a concentration of a third color component of the first pixel and a concentration of the third color component of the second pixel; and a control unit configured to control the process unit to perform, without increasing the concentration of the third color component of the second pixel, the second process and not to perform the first process on the basis of a determination by the determination unit that the concentration of the predetermined color component of the first pixel is deep and the concentration of the third color component of the second pixel is light.
