Problems to be Solved by the Invention

[0006] Conventionally, in comics, doujinshi, etc., in order to represent the skin color, which is a color representing the skin part of a character image and is expressed by yellow and magenta, a retouching process, which is a process of replacing magenta in the skin part with pink, has been performed manually. However, there has been a problem that users other than designers cannot perform the above retouching process.

[0007] An object of the present invention is to enable replacement of magenta with pink in expression without going through a manual retouching process when an image is CMYK-converted and magenta is replaced with pink.

Means for Solving the Problems

[0008] To achieve the above object, an information processing apparatus according to a first aspect includes a processor, and when the processor receives an image and inputs a magenta plate when the received image is CMYK-converted, the processor outputs at least one of a magenta plate and a pink plate that fluoresces. When the input magenta amount, which is the amount of the magenta plate when CMYK-converted, is in a region less than a predetermined threshold, the magenta plate is not output and only the pink plate is output. When the region is equal to or greater than the threshold, the processor outputs the image obtained by performing color conversion using a profile that outputs both the magenta plate and the pink plate.

[0009] Further, in the information processing apparatus according to the second aspect, in the information processing apparatus according to the first aspect, the processor outputs the image obtained by performing color conversion using a profile in which the output amount of the pink plate increases as the input magenta amount increases.

[0011] Further, in the information processing apparatus according to the fourth aspect, in the information processing apparatus according to any one of the first to third aspects, when the input magenta amount is equal to or greater than the predetermined threshold, the processor outputs the magenta plate and the pink plate, and performs color conversion using a profile in which the difference between the output amount of the pink plate and the output amount of the magenta plate is a predetermined difference amount, and outputs the image.

[0012] Further, in the information processing apparatus according to the fifth aspect, in the information processing apparatus according to the fourth aspect, the processor outputs the image obtained by performing color conversion using a profile in which, regardless of the input magenta amount, the difference between the input magenta amount and the output amount of the pink plate is less than the predetermined difference amount.

[0013] Further, in the information processing apparatus according to the sixth aspect, in the information processing apparatus according to the fourth or fifth aspect, when the input magenta amount is equal to or greater than the predetermined threshold, the processor performs color conversion using a profile in which the difference between the output amount of the magenta plate that increases as the input magenta amount increases and the output amount of the pink plate that increases as the input magenta amount increases is less than the predetermined difference amount, and outputs the image.

[0014] Further, in the information processing apparatus according to the seventh aspect, in the information processing apparatus according to any one of the first to sixth aspects, when the input magenta amount is equal to or greater than the predetermined threshold, the processor always outputs the image obtained by performing color conversion using a profile in which the output amount of the pink plate is always greater than the output amount of the magenta plate.

[0015] Further, in the information processing apparatus according to the eighth aspect, in the information processing apparatus according to any one of the first to seventh aspects, the predetermined threshold is 20.

[0016] Further, in the information processing apparatus according to the ninth aspect, in the information processing apparatus according to the fifth aspect, the processor outputs the image obtained by performing color conversion using a profile in which the difference between the input magenta amount and the output amount of the pink plate is 0 regardless of the input magenta amount.

[0017] Furthermore, in order to achieve the above object, the information processing program according to the tenth aspect causes a computer to execute a process of receiving an image and, when inputting a magenta plate at the time of CMYK-converting the received image, outputting at least one of a magenta plate and a pink plate that fluoresces, and when the input magenta amount, which is the amount of the magenta plate at the time of the CMYK conversion, is in a region less than a predetermined threshold, not outputting the magenta plate and outputting only the pink plate, and when the region is equal to or greater than the threshold, outputting the image obtained by performing color conversion using a profile that outputs the magenta plate and the pink plate.

Advantages of the Invention

Mode for Carrying Out the Invention

[0028] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings. In each drawing, the same or equivalent constituent elements and parts are given the same reference numerals. Also, the dimensional ratios in the drawings are exaggerated for the convenience of explanation and may be different from the actual ratios.

[0029] As shown in FIG. 1, the information processing system 100 according to the present embodiment includes an image output device 10 and an information processing device 20.

[0030] In the present embodiment, a digital multifunction device having an image printing function, an image transmission function, etc. is applied as the image output device 10. However, as the image output device 10, an image output device having only one of these functions may be applied.

[0031] Next, the hardware configuration of the information processing device 20 according to the present embodiment will be described. In the present embodiment, a personal computer is applied as the information processing device 20. However, any information processing device such as a server computer may be applied as the information processing device 20. The information processing device 20 according to the present embodiment includes a CPU 21, a memory 22 as a temporary storage area, a non-volatile storage unit 23, an input unit 24, a display unit 26, and a communication I / F unit 28. Each configuration is connected to each other via a bus B2.

[0032] The storage unit 23 is realized by a storage device such as an HDD, an SSD, or a flash memory. Note that an information processing program 23A is stored in the storage unit 23 as a storage medium. The CPU 21 reads the information processing program 23A from the storage unit 23 and expands it in the memory 22, and sequentially executes the processes included in the information processing program 23A.

[0033] The input unit 24 includes a pointing device such as a mouse and a keyboard, and is used to receive various input information.

[0034] The display unit 26 is, for example, a liquid crystal display, and displays various information. The display unit 26 may adopt a touch panel method and function as the input unit 24.

[0035] The communication I / F unit 28 is an interface for the information processing apparatus 20 to communicate with an external apparatus such as the image output apparatus 10. For this communication, for example, a wired communication standard such as Ethernet (registered trademark) or FDDI is used.

[0036] Next, with reference to FIGS. 2 and 3, the operation of the information processing apparatus 20 according to the present embodiment will be described. When an instruction to start the execution of the information processing program 23A is input via the input unit 24 by the user, the CPU 21 executes the information processing program 23A, and the information processing shown in FIG. 2 is executed.

[0037] In step 100, the CPU 21 waits until an image is received. Hereinafter, the image received by the CPU 21 in this step is referred to as a "received image".

[0038] In step 102, the CPU 21 performs CMYK conversion on the received image and obtains an input magenta amount which is the amount of the magenta plate at the time of the conversion.

[0039] In step 104, the CPU 21 acquires information on a magenta profile representing the amount of magenta toner which is the amount of the magenta plate output according to the input magenta amount from the storage unit 23.

[0040] In step 106, the CPU 21 acquires, from the storage unit 23, information on a pink profile representing the amount of pink toner, which is the amount of the fluorescent-coloring pink plate (hereinafter simply referred to as the "pink plate") output according to the input magenta amount. Note that the above pink plate is a color that expands the color gamut represented by the cyan plate, magenta plate, yellow plate, and black plate when added to the cyan plate, magenta plate, yellow plate, and black plate.

[0041] Regarding the information on the magenta profile and the pink profile acquired by the CPU 21 in steps 104 and 106, it will be described later with reference to FIG. 3.

[0042] In step 108, the CPU 21 performs color conversion of the received image using the profiles acquired in steps 104 and 106. Then, the CPU 21 outputs a color-converted image, which is the image on which the above color conversion has been performed, to the image output device 10, and ends this information processing.

[0043] FIG. 3 is a graph showing an example of the information on the magenta profile and the pink profile stored in the storage unit 23. In the above graph, the vertical axis represents the amount of pink toner and the amount of magenta toner (in the example shown in FIG. 3, "M toner"), and the horizontal axis represents the input magenta amount (in the example shown in FIG. 3, LUT input). Also, in the above graph, the dotted line represents the pink profile, and the solid line represents the magenta profile. As shown in FIG. 3, in the region where the input magenta amount is less than 20%, the magenta profile does not output the magenta plate. However, even in such a region, the pink profile outputs the pink plate.

[0044] On the one hand, in the case of an area where the input magenta amount is 20% or more, the magenta profile outputs a magenta plate, and as the input magenta amount increases, the magenta toner amount increases. Also, as the input magenta amount increases, the pink profile also increases the pink toner amount. Therefore, in this area, the input magenta amount is in a proportional relationship with the pink toner amount and the input magenta amount is in a proportional relationship with the magenta toner amount. Note that in this area, the pink profile outputs a pink plate such that the pink toner amount is always more than the magenta toner amount.

[0045] Also, in this area, the magenta toner amount that increases as the input magenta amount increases is less than the pink toner amount that increases as the input magenta amount increases. Therefore, in this area, as the input magenta amount increases, the difference between the pink toner amount and the magenta toner amount increases. However, the difference between the pink toner amount and the magenta toner amount may be a predetermined amount and may be constant (for example, 30%). Also, the difference between the increasing pink toner amount and the increasing magenta toner amount is a smaller amount than the difference between the pink toner amount and the magenta toner amount.

[0046] Also, as shown in FIG. 3, the pink profile always outputs a pink plate such that the pink toner amount also increases as the input magenta amount increases. At this time, the difference between the input magenta amount and the pink toner amount is a smaller value than the difference between the pink toner amount and the magenta toner amount in the case of the area where the input magenta amount is 20% or more. Note that as shown in FIG. 3, the difference between the input magenta amount and the pink toner amount may be 0, in other words, the input magenta amount and the pink toner amount may be the same value.

[0047] Note that in the example shown in FIG. 3, the upper limits of the pink toner amount and the magenta toner amount are 100%. However, these upper limit amounts may be higher than 100%. Also, the threshold value of the input magenta amount for determining whether the magenta profile outputs a magenta plate or not may be within the range from a value larger than 20% by a predetermined amount to a value smaller than 20% by a predetermined amount.
