Description

Color sampling method, information processing method, device and computer readable storage medium

Technical Field

Embodiments of the present disclosure relate to color identification and determination of objects to be tested. More particularly, the present disclosure relates to a color sampling method, an information processing method, an apparatus, and a computer-readable storage medium.

Background

In industrial applications and in life practices it is often necessary to obtain the colour of an object. For example, it is necessary to accurately confirm whether the color of an object is the same as the color of a sample, or whether the color of an object is the same as another object. One typical industrial application scenario is in the distribution industry. The situation that the cloth meeting the requirement is selected according to the sample color, or whether the colors of the two batches of cloth are the same or not is confirmed, and even the difference between the colors of the cloth needs to be accurately confirmed often occurs.

Conventionally, a device for detecting the color of an object to be measured is generally called a color sampling device. At present, a color sampling pen is generally adopted as a color sampling device to sample color of an object. For example, the color extracting pen can be held close to an object, and the color extracting function is triggered to directly extract the color of the object. The acquired color is directly displayed on the color acquiring pen. In this way, the request for triggering the color picking function, the color picking process and the display of the picked colors are all directly finished on the color picking pen, and remote color picking cannot be realized. In addition, since the color sampling pen generally does not have the functions of processing and comparing color information, it cannot implement a scheme of comparing the detected color information with the color of the sample. Another method for determining the color of the object to be detected is to directly distinguish the color by human eyes, and to distinguish the color by human eyes by using a gray scale card during color comparison. The manual mode can not realize color picking and color comparison at different places, and is time-consuming, labor-consuming and low in precision.

Detailed Description

Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The term "include" and variations thereof as used herein is meant to be inclusive in an open-ended manner, i.e., "including but not limited to". Unless specifically stated otherwise, the term "or" means "and/or". The term "based on" means "based at least in part on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.

As described above, the conventional color sampling method is to directly color the object to be measured by using a color sampling pen, or to obtain the color information of the object by a manual method identified by human eyes. However, these conventional color extraction methods cannot meet the requirements of off-site color extraction and off-site color comparison. For example, the need for remote color extraction may occur in a scene where a user who wants to extract color is not located with the color extracting device. The requirement of off-site color comparison may occur in a scene where the object to be colored is not in the same place as the sample color, or where two objects to be colored are not in the same place. At this time, the conventional method of directly operating the color pen to obtain the color cannot achieve the above purpose. The manual color comparison has low efficiency and low precision, and can not realize color extraction or color comparison in different places.

To address, at least in part, one or more of the above problems and other potential problems, embodiments of the present disclosure propose a color extraction method. In this arrangement, the colour fetching device is able to communicate with the control device using a communications protocol. In this way, the control device can operate the color fetching device via the communication protocol without having to include the color fetching device. In this way, the control device and the color taking device can be realized separately. On this basis, the embodiment of the present disclosure can also effectively implement remote processing of color information, for example, implement color matching processing of comparing two color information to determine whether there is a difference therebetween.

Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Fig. 1 shows an architecture diagram of a system 100 of a color extraction method according to an embodiment of the present disclosure. It should be understood that the structure and function of the system 100 as shown in fig. 1 are for illustration purposes only and do not imply any limitation as to the scope of the disclosure. Embodiments of the present disclosure may be embodied in different structures and/or functions.

As shown in fig. 1, the system 100 includes a color extracting device 110, a control device 120, and an information processing device 130. In general, the color sampling device 110 may be used to determine the color of an object under test, the control device 120 may be used to interact with a user (e.g., receive a color sampling request from a user and provide feedback to the user), and the information processing device 130 may be used to process color information. At least two of the three have the ability to communicatively couple, the relationship of which will be described in detail below. In some embodiments, the color-taking device 110, the control device 120, and the information processing device 130 may be located in the same geographic area, and in other embodiments, they may be remote from each other.

It should be understood that while three devices are shown in system 100, not all three are necessary. For example, in an embodiment involving only communication between the color-taking device 110 and the control device 120, the information processing device 130 may not be provided. Similarly, in embodiments involving only communication between the color-taking device 110 and the information processing device 130, the control device 120 may not be provided; whereas in embodiments involving only communication between the control device 120 and the signal processing device 130, the color extraction device 120 may not be provided.

In some embodiments, the color sampling device 110 may acquire color information of the object to be detected by using a color sampling apparatus to detect the color of the object to be detected. Specifically, the color sampling device may be implemented by various possible sensors, for example, an XYZ white sensor, or other color sampling sensors available in the art (such as an RGB color sensor, a sensor based on an LUV color model, a sensor based on a Lab color model, a sensor based on a CMYK color model, etc.), and the like, and the embodiments of the present disclosure are not limited in this respect.

In the embodiments of the present disclosure, the "object to be measured" refers to an object whose color information needs to be detected, such as cloth, shoes, hats, clothes, belts, satchels, and the like. It should be understood that this is by way of example only and is not intended to limit the scope of the present disclosure.

In some embodiments, the color extraction device 110 may also be used to store the determined color information of the object under test, historical color information, and other related information. Specifically, the storage function may be implemented by various types of registers, flash memories, and the like.

In some embodiments, the color sampling device 110 can also be used to perform color comparison and give the comparison result. The object to be color-compared is, for example, color information of each object to be measured acquired by the color acquiring device 110, or may be color information of the object to be measured and reference color information. The reference color information may be previously stored in the color fetching device 110, may be directly input by the user on the color fetching device 110, or may be received by the color fetching device 110 using a communication protocol in the following manner. Embodiments of the present disclosure are not limited in this respect.

In some embodiments, the color fetching device 110 may also communicate with other entities using a communication protocol, thereby providing the ability to be remotely triggered for color fetching. For example, the rendering device 110 may establish communication 101/102 with the control device 120/information processing device 130 using a communication protocol. Thus, using the communication protocol, the color fetching device 110 may remotely receive the relevant color fetching request from the control device 120 or other entity, and may also remotely transmit the color fetching result to the control device 120 or the information processing device 130. Therefore, the color taking device can be remotely triggered or remotely provided with a color taking result, and remote color taking is realized. In a further embodiment, the communication protocol may be at least one of a bluetooth protocol, a USB protocol, and a Wifi protocol, but may be other communication protocols known in the art. Embodiments of the present disclosure are not limited in this respect.

In some embodiments, the control device 120 is also capable of communicating with other entities using a communication protocol, thereby providing the ability to remotely trigger color fetches. For example, the control device 120 may establish communication 101/103 with the color extraction device 110/information processing device 130 using a communication protocol. With this communication protocol, the control device 120 may, for example, issue a color extraction request to the color extraction device 110 and trigger the color extraction device 110 to perform a color extraction operation based on the request, and may also receive a returned color extraction result from the color extraction device 110 or receive various types of information from the information processing device 130.

Alternatively, the control device 120 may also be used to receive requests from the user (e.g., color-fetching requests), or to return relevant results to the user (e.g., color-fetching results), enabling interaction with the user (e.g., by way of visual or voice prompts, etc.).

Additionally, the control device 120 may also perform color comparison and give the comparison result. The object to be subjected to color comparison is, for example, color information of each object to be measured returned from the color sampling device 110, or may also be color information of the object to be measured and reference color information returned from the color sampling device 110. The reference color information may be previously stored in the control device 120 or may be input by a user directly on the control device 120, and embodiments of the present disclosure are not limited in this respect. In addition, the control device 120 may be used to store color information of the object to be measured returned from the color sampling device 110, historical color information, and other related information. Specifically, the storage function may be implemented by various types of registers, flash memories, and the like.

In some embodiments, the information processing device 130 is also capable of communicating with other entities using a communication protocol to provide information processing for the other entities. For example, the information processing device 130 may establish communication 102/103 with the color drawing device 110/control device 120 using a communication protocol. Thereby making it possible to utilize the information processing apparatus 130 to assist the color-taking apparatus 110 or the control apparatus 120 in processing information. For example, the information processing apparatus 130 may receive color information to be compared or reference color information from the color sampling apparatus 110 or the control apparatus 120. After the color comparison is completed, the color comparison result is returned to the color acquiring device 110 or the control device 120 through the communication module.

An architecture diagram of a system 100 in which a color extraction method according to an embodiment of the present disclosure is implemented is described above with reference to fig. 1. It should be understood that the above description is merely exemplary of exemplary capabilities that each device in system 100 has and should not be taken as limiting the present disclosure. Each device may well include more or less than the exemplary capabilities described above.

The technical solution of the present disclosure is specifically described below by fig. 2 to 4. The embodiments of fig. 2-4 are all described with the aid of the system 100 shown in fig. 1. It should be understood that although the detailed description above refers to functions possessed by several devices or devices of the system 100, such partitioning is merely exemplary and not mandatory. Indeed, two or more of the devices or related features and functions described above may be embodied in one apparatus according to embodiments of the present disclosure. Conversely, the features and functions of one apparatus described above may be further divided into embodiments by a plurality of means.

Fig. 2 shows a flow diagram of a method 200 of color extraction according to an embodiment of the present disclosure. In the embodiment shown in fig. 2, the various actions are performed by, for example, a processor. Method 200 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.

At block 202, a color fetch request is received at a color fetch device from a control device using a communication protocol. In some embodiments, the color fetching request may come from a user input on the control device 120 and be sent to the color fetching device 110 via a communication module of the control device 120. The request may be implemented in the form of an instruction. In some embodiments, after receiving the instruction, the color fetching device 110 first confirms whether it has established a communication connection with the control device 120 directly. If a communication connection is established, the shading device performs a related action based on the shading request, as described later in block 204. Otherwise, if the communication is not established, a process of establishing a communication connection (as described in detail later) is triggered, and a related action is performed based on the color extraction request after the communication connection is established, as described in later block 204.

In some embodiments, before the process of receiving the color drawing request from the control device 120 by using the communication protocol at the color drawing device 110, a process of establishing a communication connection between the color drawing device 110 and the control device 120 is also included, so that the color drawing device 110 and the control device 120 can communicate by using the communication protocol.

The communication connection may be established in a number of ways. In some embodiments, a user-entered connection request may be received at the control device 120, which may include, for example, relevant parameter values (e.g., connection characteristic values, etc.) for indicating in which manner a connection is desired to be established. Next, the connection request is issued to the color-taking device 110 through the communication module of the control device 120. After receiving the request, the color extraction device 110 performs corresponding connection establishment processing, and sends an indication that the connection establishment is successful after the connection is successfully established.

It should be understood that the above-mentioned process of establishing the communication connection may be performed when the color fetching device 110 and the control device 120 are connected for the first time, or may be performed each time the control device 120 issues a color fetching request, so as to ensure that there is an effective communication connection between the color fetching device 110 and the color fetching device.

In still further embodiments of the present disclosure, after the communication connection is established, an indication of successful connection establishment may also be output to the control device using the communication protocol to alert the control device that the connection has been established. Alternatively or additionally, information associated with the color-fetching device may also be output to the control device. Such information includes, but is not limited to, the name of the color-taking device, specifications, accuracy, geographic location, etc.

At block 204, based on the color extraction request, color information of the object under test is determined. In some embodiments, the color-fetching means of the color-fetching device 110 may be implemented using an XYZ white sensor, as described with reference to fig. 1. Accordingly, determining the color information of the object to be measured in block 204 includes acquiring XYZ color information of the object to be measured using a color taking device.

In some embodiments, determining the color information of the object to be measured may include, in addition to determining the color of the object to be measured using the color taking device, optionally performing preliminary processing on the color to obtain the color information of the object to be measured. For example, in embodiments where the color fetching device is implemented with RGB color sensors, RGB color information may be determined based on the detected colors. Alternatively, in other embodiments where the color-taking device is implemented using an XYZ white sensor, the preliminary processing further comprises converting XYZ color information to RGB color information. This conversion can be done via the Lab value as an intermediate value.

At block 206, the determined color information of the object under test is output to the control device using the communication protocol. It should be appreciated that the communication protocol mentioned in block 206 may be the same communication protocol as the communication protocol mentioned in block 202, or may be a different communication protocol. For example, when the communication connection mode is changed between the color sampling device and the control device during the color sampling process, the communication protocols used twice may be different. It should be noted that, in the case where the communication protocol is changed between the color sampling device and the control device, the connection needs to be reestablished between the color sampling device and the control device in the manner described above. In some embodiments, the communication protocols include at least one of bluetooth protocol, USB protocol, Wifi protocol, but are not limited thereto.

The color extraction method according to the embodiment of the present disclosure is described in detail above with reference to fig. 2, and in the method, a communication protocol is introduced to remotely receive a color extraction request and trigger color detection, so that remote color acquisition can be realized, and color comparison of a plurality of objects to be measured located in different places on the basis of the remote color acquisition is possible. The method 300 of color extraction according to an embodiment of the present disclosure is further described below with reference to fig. 3.

Fig. 3 shows a schematic diagram of a color extraction method 300 according to an embodiment of the present disclosure. In the embodiment shown in fig. 3, the various actions are performed by, for example, a processor. Method 300 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.

At block 302, a first color extraction request is sent to a first color extraction device using a communication protocol, where the first color extraction request is used to trigger the first color extraction device to determine color information of a first object to be detected. It should be understood that the first color extracting device is only used for distinguishing from other color extracting devices, and is not used as a limitation on the function of the color extracting device itself. The first color sampling device may be implemented, for example, according to the color sampling device 110 shown in fig. 1. The description of the color-fetching device 110 with reference to fig. 1 is applicable to the first color-fetching device.

In some embodiments, the first color-fetching request may come from a user input on the control device 120 and be sent to the first color-fetching device via a communication module of the control device 120. The request may be implemented in the form of an instruction. In some embodiments, after the first color-extracting device receives the instruction, it first confirms whether it has established a communication connection with the control device 120 directly. And if the communication connection is established, the first color extracting device determines the color information of the object to be detected based on the first color extracting request. Otherwise, if the communication is not established, the process of establishing the communication connection described above with reference to fig. 2 is triggered (no longer described), and the determination of the color information of the object to be detected is performed based on the first color extraction request after the communication connection is established.

In some embodiments, a communication connection establishment request is sent to the first color fetching device before sending the first color fetching request. The communication connection establishment request is used for triggering the establishment of a communication connection with the first color extracting device so as to enable the communication with the first color extracting device by utilizing the communication protocol. For a specific procedure of establishing a communication connection, reference is made to the procedure of establishing a communication connection described above with reference to fig. 2 (which is not described in detail).

It should also be understood that the above-mentioned process of establishing the communication connection may be performed when the first color-extracting device and the control device 120 are connected for the first time, or may be performed each time the control device 120 issues a color-extracting request, so as to ensure that there is an effective communication connection between the first color-extracting device and the first color-extracting device.

At block 304, the determined color information of the first object to be measured is received from the second color-taking device using the communication protocol. It should be appreciated that the communication protocol mentioned in block 304 may be the same communication protocol as the communication protocol mentioned in block 304, or may be a different communication protocol. For example, when the communication connection mode is changed between the first color extracting device and the control device during color extraction, the communication protocols used twice may be different. It should be noted that, in the case where the communication protocol is changed between the first color extracting apparatus and the control apparatus, the connection needs to be reestablished between the first color extracting apparatus and the control apparatus in the manner described above. In some embodiments, these communication protocols may be at least one of bluetooth protocol, USB protocol, Wifi protocol, but may be other communication protocols known in the art.

In some embodiments, the color-fetching means of the color-fetching device 110 may be implemented using an XYZ white sensor, as described with reference to fig. 1. Accordingly, receiving the determined color information of the first object to be measured in block 304 includes receiving XYZ color information.

In some embodiments, color information of the object under test may be indicated to the user. Specifically, the color information may be indicated to the user in a visual or voice prompt or the like. In an alternative or alternative embodiment, the determined color information of the first object to be measured may be sent to the information processing apparatus 130 for subsequent processing (e.g., color comparison) of the color information using the processing capability of the information processing apparatus 130. In other alternative or alternative embodiments, the determined color information of the object under test may be stored in the control device 120, as described above for the control device 120 with reference to fig. 1.

In some embodiments, the communication protocol may also be utilized to send a second color-fetching request to a second color-fetching device. The second color taking request is used for triggering the second color taking device to detect the color information of the second object to be detected. In some embodiments, the first color extracting device and the second color extracting device may be the same device or different devices, and embodiments of the present disclosure are not limited herein. When the objects to which the color is taken twice are not in the same place, two sets of color taking equipment are needed to respectively take the colors of the two objects to be measured. At this time, the first color sampling device and the second color sampling device are different.

In these embodiments, the detected color information of the second object to be measured is also received from the second color sampling device using the communication protocol. It should also be understood that the communication protocol utilized to send the color fetch request to the second color fetch device, the communication protocol utilized to receive the color information from the second color fetch device, the communication protocol mentioned in block 302, and the communication protocol mentioned in block 304 may be the same communication protocol or may be different communication protocols. In some embodiments, the communication protocols may be at least one of: bluetooth protocol, USB protocol, Wifi protocol.

In still other embodiments, a difference between the color information of the first object under test and the color information of the second object under test may be further determined. As described above with reference to fig. 1, the control device 120 may itself include a color comparison module for performing color comparison and providing a comparison result. Therefore, when the color information of the two objects to be measured has been obtained, the control device 120 can directly perform color comparison to obtain the color difference between the first object to be measured and the second object to be measured. Further, the color difference may also be output to the user (e.g., by visual or voice prompt, etc.).

In some embodiments, the control apparatus 120 also receives reference color information in order to determine a difference between the color information of the first object to be measured and the reference color information. Specifically, the reference color information is usually a preset color value, and it is possible to accurately confirm whether the color of the first object to be measured matches the reference color by calculating the difference between the color information of the first object to be measured and the reference color information. In a further embodiment, receiving the reference color information comprises: the reference color information is received using a communication protocol. Similarly, the communication protocol utilized to receive the reference color information may be the same as or different from the communication protocol utilized to receive the first color information and the second color information described previously. In some embodiments, the communication protocol utilized to receive the reference color information may also be at least one of: bluetooth protocol, USB protocol, Wifi protocol.

The method of color extraction according to some embodiments is set forth in detail above with reference to FIG. 3. By the method, remote control over the color taking equipment can be effectively implemented, so that remote color taking is realized, and remote color comparison is further effectively implemented.

Fig. 4 shows a schematic diagram of an information processing method 400 according to an embodiment of the present disclosure. In the embodiment shown in fig. 4, the various actions are performed by, for example, a processor. Method 400 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.

At block 402, first color information of a first object under test is received, the first color information being determined at a first color-taking device based on a color-taking request received from a first control device using a communication protocol.

At block 404, second color information of a second object under test is received, the second color information being determined at a second color-taking device based on a color-taking request received from a second control device using a communication protocol.

It should be appreciated that the communication protocol referred to in block 402 may be the same communication protocol as the communication protocol referred to in block 404, or may be a different communication protocol. In some embodiments, the communication protocols may be at least one of: bluetooth protocol, USB protocol, Wifi protocol.

It should also be understood that the first and second color-fetching devices may be the same device or different devices, both of which may be implemented with the color-fetching device 110 shown in fig. 1. The description of the color sampling device 110 with reference to fig. 1 is applicable to the first color sampling device and the second color sampling device. When the objects to which the color is taken twice are not in the same place, two sets of color taking equipment are needed to respectively take the colors of the two objects to be measured. At this time, the first color sampling device and the second color sampling device are different.

It should also be understood that the first control device and the second control device may be the same device or different devices, both of which may be implemented with the control device 120 shown in fig. 1. The description of the control device 120 with reference to fig. 1 is applicable to the first control device and the second control device.

In some embodiments, at least one of the first color information and the second color information comprises XYZ color information. As described with reference to fig. 1, the color extracting means of the color extracting device 110 may be implemented using an XYZ white sensor. Accordingly, at least one of the first and second color information received in

blocks

402 and 404 should include XYZ color information. In some embodiments implemented with an XYZ white sensor, further comprising converting XYZ color information to RGB color information. This conversion is usually done via Lab values as intermediate values.

At block 406, a difference between the first color information and the second color information is determined. As described above with reference to fig. 1, the information processing apparatus 130 has an information processing capability and can perform color matching based on color information. Therefore, when the color information of the two objects to be measured has been obtained, the information processing apparatus 130 can directly perform color comparison to obtain the color difference between the first object to be measured and the second object to be measured. Still further, the determined color difference may also be sent to at least one of the first control device and the second control device for feedback to the user (e.g., by visual or voice prompt, etc.).

In some embodiments, the information processing apparatus 130 also receives the reference color information to determine a difference between the color information of the first object to be measured and the reference color information. Specifically, the reference color information is usually a preset color value, and it is possible to accurately confirm whether the color of the first object to be measured matches the reference color by calculating the difference between the color information of the first object to be measured and the reference color information. In a further embodiment, receiving the reference color information comprises: the reference color information is received using a communication protocol. Similarly, the communication protocol utilized to receive the reference color information may be the same as or different from the communication protocol utilized to receive the first color information and the second color information described previously. In some embodiments, the reference color information may be received using at least one of a bluetooth protocol, a USB protocol, and a Wifi protocol. It should be understood that other communication protocols may be utilized for the above-described reception, and the disclosure is not limited in this respect.

The information processing method according to some embodiments is set forth in detail above with reference to fig. 4. By this method, it is possible to perform remote color comparison by effectively utilizing the processing capability of the information processing apparatus 130. This embodiment can obtain a higher accuracy of the color comparison result due to the better processing capability of the information processing device 130, and on the other hand, can avoid performing the color comparison on the control device 120 or the color sampling device 110, thereby simplifying the structures of the control device 120 and the color sampling device 110.

FIG. 5 illustrates a schematic diagram of an interaction 500 of the

device

110 and 130 for color matching and color comparison according to an embodiment of the disclosure. It should be understood that the flow 500 is schematic and is only used to illustrate the implementation under some embodiments. In other embodiments, more or fewer steps than those shown in flow 500 may be employed, or portions of the steps of flow 500 may be modified.

In the embodiment shown in fig. 5, for color matching, the control device 120 first issues 501 a connection request to the color matching device 110 for establishing a communication connection between the control device 120 and the color matching device 110. In some embodiments, the connection request 501 may include a type of communication protocol. The color fetching device 110 establishes communication with the control device 120 in response to the request 501 and, upon successful establishment of a communication connection, sends 502 an indication back to the control device 120 of the connection establishment.

Next, the control device 120 issues 503 a color sampling request for the object to be detected to the color sampling device 110, so as to trigger the color sampling device 110 to perform color sampling on the object to be detected. The color-taking device 110 determines color information of the object to be measured in response to the request 503, and returns 504 the color information 504 to the control device 120. The control device 120 thus obtains color information of the object to be measured by means of the color sampling device 110, and completes color sampling of the object.

In contrast to the conventional color sampling method, the process 501-504 allows the control device 120 that wants to acquire the object color to have no color sampling function, and to perform color sampling by operating the color sampling device 110 using a communication protocol. Thus, the control device and the color-taking device can be realized separately.

In some embodiments, the control device 120 may further send 505 the color information obtained from the color extraction device 110 to the information processing device 130 for separate saving. In other embodiments, such color information may also be stored on the control device 120 itself. Further, the determined color information may be directly transmitted from the color extracting device to the information processing device 130 for saving.

In a scene where color comparison is required, processes 506 and 507 similar to the

aforementioned processes

503 and 504 may be further included to obtain color information of another object to be measured by the color taking device 110 and send 508 the color information 508 of the other object to be measured to the information processing device 130 by the control device 120. As previously described with reference to fig. 1-4, in other embodiments, color information of another object under test may be determined using another set of color extraction devices and/or control device 120 and sent to information processing device 130 (not shown in the interactive operational diagram). Also, the color information may be stored on the control device 120 itself. Further, the determined color information may be directly transmitted from the color extracting device to the information processing device 130 for saving.

Subsequently, the control apparatus 120 transmits 509 a color comparison request to the information processing apparatus 130, thereby triggering the information processing apparatus 130 to perform color comparison based on the received pieces of color information. The result of the color comparison is returned 510 by the information processing apparatus 130 to the control apparatus 120.

Through the

above process

501 and 510, color comparison may be performed with the information processing device 130. This approach can obtain a higher accuracy of color comparison results due to the better processing capability of the information processing apparatus 130, while also avoiding performing color comparison on the control apparatus 120 or the color taking apparatus 110, so as to simplify the structures of the control apparatus 120 and the color taking apparatus 110.
