Abstract:
1. An image processing apparatus performing processes including a color shift correction process for correcting a color shift of image data, and a halftone process for quantizing image data, the apparatus comprising: an acquisition unit configured to acquire a value of factor that affects a quality of the image data; a determination unit configured to determine whether to execute the color shift correction process before or after the halftone process, based on the acquired value of factor; and a control unit configured to control the color shift correction process in accordance with the determination so that the color shift correction process is executed before or after the halftone process, wherein the value of factor corresponds to a color shift amount of the image, a resolution of image formation, and a number of gradation levels obtained through a quantization by the halftone process, wherein the determination unit performs determinations, in order, of whether or not each of the color shift amount of the image, the resolution of image formation, and the number of gradation levels obtained through a quantization by the halftone process is greater than a respective predetermined value, and wherein the control unit controls the color shift correction process in accordance with the determinations performed by the determination unit, so that the color shift correction process is executed before or after the halftone process.
