1. An image processing apparatus configured to process image data for a recording apparatus, the recording apparatus being configured to record an image on a recording medium by applying ink from a recording device while relatively conveying the recording device and the recording medium in a second direction intersecting a first direction, the recording device including a first nozzle row in which a plurality of nozzles configured to discharge a first ink is arranged in the first direction and a second nozzle row in which a plurality of nozzles configured to discharge a second ink of different color from that of the first ink is arranged in the first direction, the first and second nozzle rows being arranged in the second direction, the image processing apparatus comprising:

  • a color conversion unit configured to color-convert image data including a plurality of components corresponding to a plurality of colors into image data including a plurality of components in a color space reproducible by the recording apparatus;

    a color correction unit configured to color-correct the image data including the plurality of components color-converted by the color conversion unit into image data including a plurality of components by using color correction information for correcting a color shift due to a variation in a discharge characteristic of the nozzles; and

    a generation unit configured to generate ink color data indicating amounts of application of the respective first and second inks based on the image data including the plurality of components color-corrected by the color correction unit,wherein in a case where image data indicating a predetermined color having a hue corresponding to the first ink is color-corrected by using first information as the color correction information, ink color data generated based on the color-corrected image data indicating the predetermined color indicates that the first ink is applied and the second ink is not applied, andwherein in a case where the image data indicating the predetermined color is color-corrected by using second information as the color correction information, the ink color data generated based on the color-corrected image data indicating the predetermined color indicates that the second ink is applied.
