Information processing apparatus, control method, and product performing multiplexing processing changing a component in different color spaces with respect to printing and non-printing areas
An information processing apparatus includes a determination unit configured to determine a printing area and a non-printing area in image data, and an execution unit configured to execute first multiplexing processing by changing a U component in a YUV color space with respect to an area determined as a printing area in the image data and to execute second multiplexing processing by changing a Y component in a CMYK color space with respect to an area determined as a non-printing area in the image data.
1. An information processing apparatus comprising:
a determination unit configured to determine a printing area and a non-printing area in image data; and
an execution unit configured to execute first multiplexing processing by changing a U component in a YUV color space with respect to an area determined as a printing area in the image data and to execute second multiplexing processing by changing a Y component in a CMYK color space with respect to an area determined as a non-printing area in the image data.
2. The information processing apparatus according to claim 1 , wherein the second multiplexing processing is multiplexing processing for changing a Y component in a YUV color space to a larger extent than the first multiplexing processing.
3. The information processing apparatus according to claim 1 , wherein both the first multiplexing processing and the second multiplexing processing are processing for multiplexing identical additional information.
4. A control method for an information processing apparatus, the control method comprising:
determine a printing area and a non-printing area in image data;
executing first multiplexing processing by changing a U component in a YUV color space with respect to an area determined as a printing area in the image data; and
executing second multiplexing processing by changing a Y component in a CMYK color space with respect to an area determined as a non-printing area in the image data.
5. The control method for the information processing apparatus according to claim 4 , wherein the second multiplexing processing is multiplexing processing for changing a Y component in a YUV color space to a larger extent than the first multiplexing processing.
6. The control method for the information processing apparatus according to claim 4 , wherein both the first multiplexing processing and the second multiplexing processing are processing for multiplexing identical additional information.
7. A non-transitory computer-readable storage medium storing computer-executable instructions that, when executed by a computer, cause the computer to perform a control method for an information processing apparatus, the control method comprising:
determine a printing area and a non-printing area in image data;
executing first multiplexing processing by changing a U component in a YUV color space with respect to an area determined as a printing area in the image data; and
executing second multiplexing processing by changing a Y component in a CMYK color space with respect to an area determined as a non-printing area in the image data.
