Image processing apparatus, image processing method and storage medium

1. An image processing apparatus configured to generate data for forming an image by recording at least a colored ink on a recording medium by using a printer, the image processing apparatus comprising:

an input unit configured to input image data representing an image;

a first determination unit configured to determine, based on the image data, a first recording amount for use in recording by arranging the colored ink side by side on the recording medium and a second recording amount for use in recording by stacking the colored ink at discrete positions on the recording medium; and

an output unit configured to output layout data indicating a layout of the colored ink on the recording medium, the layout data being based on the first recording amount and the second recording amount,

wherein a layer to be formed by arranging the colored ink side by side on the recording medium and a layer to be formed by stacking the colored ink at discrete positions on the recording medium are in a same region of a high-density portion of the image.

2. The image processing apparatus according to claim 1 , wherein the first determination unit determines the first recording amount which is a recording amount of the colored ink and the second recording amount which is a recording amount of the colored ink and a colorless ink, and

wherein the output unit outputs layout data indicating a layout of the colored ink and the colorless ink on the recording medium, based on the first recording amount and the second recording amount.

3. The image processing apparatus according to claim 2 , wherein the second recording amount is a constant recording amount for each region of the image.

4. The image processing apparatus according to claim 2 , further comprising a forming unit configured to form a coating layer and an uneven layer, the coating layer being formed by performing recording based on first layout data for arranging the colored ink side by side on the recording medium using the first recording amount, and the uneven layer being formed by performing recording based on second layout data for stacking the colored ink and the colorless ink on the recording medium using the second recording amount.

5. The image processing apparatus according to claim 4 , wherein the forming unit forms the uneven layer after forming the coating layer.

6. The image processing apparatus according to claim 1 , wherein the first determination unit holds in advance a table indicating a relationship between the first recording amount and the second recording amount, and determines the ratio between the first recording amount and the second recording amount by referring to the table.

7. The image processing apparatus according to claim 1 , wherein the first recording amount is a recording amount of an ink for coating the recording medium, and the second recording amount is a recording amount of an ink for adding unevenness to a surface of the image.

8. The image processing apparatus according to claim 1 , further comprising a forming unit configured to form a coating layer and an uneven layer, the coating layer being formed by performing recording based on first layout data for arranging the colored ink side by side on the recording medium using the first recording amount, and the uneven layer being formed by performing recording based on second layout data for stacking the colored ink on the recording medium using the second recording amount.

9. The image processing apparatus according to claim 8 , wherein the forming unit forms the uneven layer after forming the coating layer.

10. The image processing apparatus according to claim 1 , wherein, in a case where a first ink and a second ink having a lower transmittance than the first ink are stacked on the recording medium, the second ink is recorded at a position lower than the first ink.

11. An image processing method for generating data for forming an image by recording at least a colored ink on a recording medium by using a printer, the image processing method comprising:

inputting image data representing an image;

determining, based on the image data, a first recording amount for use in recording by arranging the colored ink side by side on the recording medium and a second recording amount for use in recording by stacking the colored ink at discrete positions on the recording medium; and

outputting layout data indicating a layout of the colored ink on the recording medium, the layout data being based on the first recording amount and the second recording amount,

wherein a layer to be formed by arranging the colored ink side by side on the recording medium and a layer to be formed by stacking the colored ink at discrete positions on the recording medium are in a same region of a high-density portion of the image.

12. A non-transitory computer-readable storage medium storing instructions that, when executed by a computer, cause the computer to perform an image processing method for generating data for forming an image by recording at least a colored ink on a recording medium by using a printer, the method comprising:

inputting image data representing an image;

determining, based on the image data, a first recording amount for use in recording by arranging the colored ink side by side on the recording medium and a second recording amount for use in recording by stacking the colored ink in discrete positions on the recording medium; and

outputting layout data indicating a layout of the colored ink on the recording medium, the layout data being based on the first recording amount and the second recording amount,

wherein a layer to be formed by arranging the colored ink side by side on the recording medium and a layer to be formed by stacking the colored ink at discrete positions on the recording medium are in a same region of a high-density portion of the image.

13. A printer configured to form an image by recording at least a colored ink on a recording medium, the printer comprising:

an input unit configured to input image data representing density of an image; and

a formation unit configured to form, based on the image data, a first layer by arranging the colored ink side by side on the recording medium and a second layer by stacking the colored ink at discrete positions on the recording medium, wherein the first layer and the second layer are in a same region of a high-density portion of the image.
