Image processor for correcting image data

A non-transitory computer-readable storage medium storing a computer-executable image-processing program executable on an image-processor, the image-processing program comprising:

• instructions for acquiring image data and ambient light data indicating a first color for a first ambient light and a second color for a second ambient light, a printed image, which corresponds to the image data, being perceived in the first ambient light as an image having a first color-appearance, the printed image being perceived in the second ambient light as an image having a second color-appearance, the image data including a first pixel data indicating a third color and a second pixel data indicating a fourth color, the third color being closer to the first color than the second color, the fourth color being closer to the second color than the first color;
• and
• instructions for correcting the first pixel data such that a third color-appearance of a pixel according to the corrected first pixel data under the second ambient light is perceived as a color-appearance that is the same as a fourth color-appearance of a pixel according to the first pixel data under the first ambient light, and correcting the second pixel data such that a fifth color-appearance of a pixel according to the corrected second pixel data under the second ambient light is perceived as a color-appearance that is different from a sixth color-appearance of a pixel according to the second pixel data under the first ambient light and a correction degree by which the correcting unit corrects the second pixel data is less than a correction degree by which the correcting unit corrects the first pixel data.

A method executed by an image processing device, the method implementing functions of the image processing device comprising:

• acquiring image data and ambient light data indicating a first color for a first ambient light and a second color for a second ambient light, a printed image, which corresponds to the image data, being perceived in the first ambient light as an image having a first color-appearance, the printed image being perceived in the second ambient light as an image having a second color-appearance, in the second ambient light, the image data including a first pixel data indicating a third color and a second pixel data indicating a fourth color, the third color being closer to the first color than the second color, the fourth color being closer to the second color than the first color;
• and
• correcting the first pixel data such that a third color-appearance of a pixel according to the corrected first pixel data under the second ambient light is perceived as a color-appearance that is the same as a fourth color-appearance of a pixel according to the first pixel data under the first ambient light, and correcting the second pixel data such that a fifth color-appearance of a pixel according to the corrected second pixel data under the second ambient light is perceived as a color-appearance that is different from a sixth color-appearance of a pixel according to the second pixel data under the first ambient light and a correction degree by which the correcting unit corrects the second pixel data is less than a correction degree by which the correcting unit corrects the first pixel data.
