Abstract

In response to reception of instructions to print a color sample from a user, first, a printing unit is caused to perform calibration. Then, after the calibration is completed in the printing unit, control is performed so that print data is generated by execution of predetermined image processing for image data representing the color sample and printing processing of the print data is performed in the printing unit.

First claim

What is claimed is:

1. An image processing apparatus comprising:
a printer; and
one or more processors configured to:
receive designation of a target color by a user;
specify, based on the designated target color, one or more candidate colors;
perform a color conversion process such that, for converting the designated target color to a color selected from the specified one or more candidate colors, the printer prints a predetermined color sample including the specified one or more candidate colors;
perform calibration in response to reception of an instruction for performing the color conversion process from the user;
perform, after the calibration is completed, a predetermined image processing based on a result of the calibration on image data representing the predetermined color sample; and
cause the printer to print the predetermined color sample based on the image data subjected to the predetermined image processing.

2. The image processing apparatus according to claim 1 , wherein the one or more processors:
determines whether or not it is necessary to perform the calibration upon receipt of the instruction for performing the color conversion process;
perform, in a case of determining that it is not necessary to perform the calibration, the color conversion process without performing the calibration.

3. The image processing apparatus according to claim 2 , wherein the one or more processors determines that it is not necessary to perform the calibration in a case where the calibration has already been performed within a predetermined period.

4. The image processing apparatus according to claim 1 , wherein the predetermined image processing includes gamma correction processing.

5. The image processing apparatus according to claim 1 , wherein the one or more processors specify a type of an object including the designed target color and perform calibration corresponding to the specified type.

6. The image processing apparatus according to claim 1 , wherein the one or more processors notify a user that the calibration is performed.

7. The image processing apparatus according to claim 6 , further comprising:
a user interface unit configured to receive user instructions,
wherein the control unit performs the notification by displaying a message to the effect that the calibration is performed on the user interface unit.

8. A method or controlling an image processing apparatus including a printer, the method comprising:
receiving designation of a target color by a user;
specifying, based on the designated target color, one or more candidate colors;
performing a color conversion process such that, for converting the designated target color to a color selected from the specified one or more candidate colors, the printer prints a predetermined color sample including the specified one or more candidate colors;
performing calibration in response to reception of an instruction for performing the color conversion process from the user;
performing, after the calibration is completed, a predetermined image processing based on a result of the calibration on image data representing the predetermined color sample; and
causing the printer to the predetermined color sample based on the image data subjected to the predetermined image processing.

9. The method according to claim 8 , further comprising:
determining whether or not it is necessary to perform the calibration upon receipt of the instruction for performing the color conversion process;
performing, in a case of determining that it is not necessary to perform the calibration, the color conversion process without performing the calibration.

10. The method according to claim 8 , wherein the predetermined image processing includes gamma correction processing.

11. A non-transitory computer readable storage medium storing a program for causing a computer to perform a method or controlling an image processing apparatus including a printer, the method comprising:
receiving designation of a target color by a user;
specifying, based on the designated target color, one or more candidate colors;
performing a color conversion process such that, for converting the designated target color to a color selected from the specified one or more candidate colors, the printer prints a predetermined color sample including the specified one or more candidate colors;
performing calibration in response to reception of an instruction for performing the color conversion process from the user;
performing, after the calibration is completed, a predetermined image processing based on a result of the calibration on image data representing the predetermined color sample; and
causing the printer to the predetermined color sample based on the image data subjected to the predetermined image processing.

12. The non-transitory computer readable storage medium according to claim 11 , further comprising:
determining whether or not it is necessary to perform the calibration upon receipt of the instruction for performing the color conversion process;
performing, in a case of determining that it is not necessary to perform the calibration, the color conversion process without performing the calibration.

13. The non-transitory computer readable storage medium according to claim 11 , wherein the predetermined image processing includes gamma correction processing.
