The image data for display is generated and transmitted. As a result, the divided images are displayed by the master panel unit 2 and the panel unit 3, and one image P is displayed using the entire display device 10. The ID of the panel unit that displays the image data is added to each image data.

Here, a transfer function executed by the master panel unit 2 and the panel unit 3 will be described. In the display device 10, since the host computer 4 is connected only to the master panel unit 2, image data is transmitted from the master panel unit 2 to each panel unit 3, and control information is transmitted from the panel unit 3 to the host computer 4. For example, control information and image data need to be relayed (transferred) by the master panel unit 2 and the panel unit 3. Therefore, the master panel unit 2 and the panel unit 3 have a function of transferring control information, image data, and the like.
When the master panel unit 2 receives control information, image data, or the like from the host computer 4 via the communication line 11, the master panel unit 2 refers to an ID added as a destination to the received control information, image data, or the like. If the destination ID is its own ID, the control information and the image data are temporarily stored in the RAM 23 and processed by the CPU 21, for example, a drawing process based on the received image data is executed to display the display panel. Display an image.

The master panel unit 2 has an ID assigned to the panel unit 3 and its I
When the control unit or image data to be transferred to the panel unit 3 is received, the control unit has information that associates with which interface 26 the panel unit 3 having D is connected. The interface 26 from which image data or the like should be output may be specified.

The panel unit 3 has a function of transferring control information, image data and the like input from any one of the interfaces 35. Among the four interfaces 35, the panel unit 3 includes an interface 35 connected to the master panel unit 2 directly or via another panel unit 3, and an interface 35 connected to the panel unit 3 having the following ID. Information to be specified is stored in the nonvolatile memory 24.
When control information, image data, or the like is input from any of the interfaces 35, the panel unit 3 determines the destination ID. And this ID is the master panel unit 2
If the ID is unique (for example, hexadecimal FF), the input control information and image data are output from the interface 35 connected to the master panel unit 2.
When the destination ID is an ID of a panel unit 3 other than itself, the panel unit 3 receives the input control information, image data, and the like from the interface 35 connected to the panel unit 3 having the next ID. Output. Destination I for input control information and image data
When D matches its own ID, the panel unit 3 stores the input control information, image data, and the like in the RAM 33 and processes them by the CPU 31.

In this way, control information, image data, etc. transmitted from the host computer 4 to the panel unit 3 are transferred from the master panel unit 2 to the panel unit 3 as shown in FIG. The data is sequentially transferred by each panel unit 3 and reaches the destination panel unit 3. Control information transmitted from the panel unit 3 to the host computer 4 or the master panel unit 2 is transferred by each panel unit 3 in the reverse order of the ID and received by the master panel unit 2. The
For example, the panel unit 3 (ID = 05) in FIG. 7B is not connected to the panel unit 3 having the next ID. Such a panel unit 3 is set to have no transfer destination at the time of the initial setting operation, and all control information and image data to which a destination different from its own ID is added are discarded without being transferred.

Thus, in the display device 10, the master panel unit 2 and the panel unit 3
By transferring control information and image data between the host computer 4, the master panel unit 2 and the panel unit 3 can individually transmit and receive image data and control information. Using this function, the display system 1 detects the deterioration state of the master panel unit 2 and the panel unit 3 based on the current consumption of the master panel unit 2 and the panel unit 3 at the time of display, and based on the detected deterioration state. Place B where each display unit 5 is placed
As a suitable location B.

FIG. 8 is a flowchart showing the arrangement location specifying process. The arrangement location specifying process is a process of specifying the arrangement location B most suitable for each display unit 5, and is executed by the host computer 4 instructing the master panel unit 2 in this embodiment.
In the arrangement location specifying process of FIG. 8, the deterioration state of the display unit 5 is a value indicating the degree of deterioration of the luminance of the display unit 5, and details will be described later. Is expressed as a deterioration level RL. Moreover, the tendency of an image means the tendency of the brightness of an image displayed on one display unit 5 arranged at one arrangement place B.
Is a value shown for each placement location B where it is placed, and will be described as a tendency level KL in the present embodiment although details will be described later.
8, as an example, the master panel unit 2 detects the deterioration state of each display unit 5 as a deterioration state detection unit, and the image tendency detection unit displays the image tendency for each arrangement place B as an example. Further, the display unit 5 in which deterioration has occurred is detected as a deterioration detection unit, but the host computer 4 may perform this.

In the arrangement location specifying process, first, the master panel unit 2 is instructed by the host computer 4 to start the arrangement location specifying process (step S11). In accordance with this instruction, the master panel unit 2 executes a deterioration state detection process that is a process for detecting the deterioration states of the master panel unit 2 and the panel unit 3 (step S12). Here, the deterioration state detection processing will be described in detail with reference to FIG.

FIG. 9 is a flowchart showing in detail the deterioration state detection process in step S12.
In the deterioration state detection process, the master panel unit 2 first displays any one of red, blue and green on the entire surface of the display panels 27 and 37 of the display unit 5. Here, for convenience of explanation, it is assumed that red is displayed on the entire surface of the display panels 27 and 37 (step S21). Next, the master panel unit 2 instructs each panel unit 3 to measure the current consumption, and measures the current consumption by the current detection unit 60 included in its own control unit 20 (step S22).
Here, according to the instruction from the master panel unit 2, the panel unit 3
Current consumption is measured by the current detector 60 provided in 0, and the measured value is transmitted to the master panel unit 2. The master panel unit 2 receives the measurement value transmitted from the panel unit 3 and waits until the measurement value is received from all the panel units 3 (step S23).
After receiving the measured values from all the panel units 3, the master panel unit 2 adds up the received measured values and the measured values of its own current detection unit 60 (step S24).

Subsequently, the master panel unit 2 obtains an average value H of current consumption of each display unit 5 based on the tabulated values, compares this average value H with the current consumption value of each display unit 5, and the comparison result Based on the above, the degree of deterioration of the luminance of each display unit 5 with respect to red is detected. Based on the degree of deterioration, the master panel unit 2 sets a red deterioration level RRL indicating the degree of deterioration of the luminance with respect to red for all the display units 5 (step S25).
Specifically, when the current consumption value of one display unit 5 is within a predetermined value T1 with respect to the average value H, the master panel unit 2 determines that the red deterioration level R
“A” is set as RL. On the other hand, when the current consumption value of one display unit 5 is separated from the average value H beyond the predetermined value T1, the master panel unit 2 sets “B” as the red deterioration level RRL for the display unit 5. Set.
Here, the predetermined value T1 is a threshold value for determining whether or not the luminance of the display unit 5 with respect to red is deteriorated so as to make the user feel uncomfortable, and the current consumption value of the panel unit 3 becomes the average value H. On the other hand, when it is within the range of the predetermined value T1, the luminance of the panel unit 3 is not deteriorated enough to make the user feel uncomfortable. On the contrary, when it is outside the range of the predetermined value T1, the user feels uncomfortable. The value is such that the luminance of the panel unit 3 with respect to the red color is deteriorated as the user learns. Accordingly, when the red deterioration level RRL of a certain panel unit 3 is “A”, the panel unit 3 is in a state in which the luminance with respect to red is not deteriorated so as to make the user feel uncomfortable. Conversely, the red deterioration level RRL Is “B”, the panel unit 3 is in a state where the luminance with respect to red is deteriorated to such an extent that the user feels uncomfortable.

As described above, the deterioration state detection processing from when red is displayed on the entire surface of all the display panels 27 and 37 until the red deterioration level RRL is set for each display unit 5 has been described with reference to the flowchart of FIG. The deterioration state detection process is performed not only for red but also for green and blue. That is, the master panel unit 2 displays each color of green and blue on the entire surface of the display unit 5, and assigns the green deterioration level GRL and the blue deterioration level BRL to all the display units 5 by the same procedure as described above. Set.

FIG. 10 is a diagram illustrating an example of the state of the deterioration level RL of each color set in each display unit 5 after executing the deterioration state detection process for each color of red, green, and blue.
As shown in FIG. 10, after the deterioration state detection process is executed, the deterioration level RL of each color is set for each display unit 5. For example, the panel unit 3 (ID = 08) arranged at the upper left of the front has a value “B” as the red deterioration level RRL and the green deterioration level GRL.
And the value “A” is set as the blue deterioration level BRL.

As described above, in the present embodiment, the deterioration state detection process is executed for each color of red, green, and blue, and the deterioration level RL is set for each color, for the following reason.
That is, various display panels such as an organic EL panel, a liquid crystal panel, and a plasma display panel display images by controlling display bodies corresponding to the three primary colors of red, blue, and green in order to perform full color display. Therefore, when the current consumption is measured in a state where red, blue or green is displayed on the entire surface of the display panels 27 and 37, only the red display body is colored, only the blue display body is colored, the green display body. Only the current consumption in the state where only the color is developed is measured. For this reason, the deterioration level RL can be reliably set based on the current consumption for each color of the display body.
Further, when a current-driven light-emitting element is used as a display body such as an organic EL panel, for example, there is a proportional relationship between current consumption and screen brightness. For example, when the red display body (light emitting element) is deteriorated so that it looks uncomfortable, the current consumption in a state where red is displayed on the entire surface is lower than usual. For this reason, it is possible to detect the degree of luminance deterioration for each color of the display body based on the current consumption for each color of the display body, and to reliably set the deterioration level RL.

Now, referring back to FIG. 8, after executing the deterioration state detection process in step S <b> 12, the master panel unit 2 displays the tendency of the luminance of the image displayed by the display unit 5 arranged in each arrangement location B for each arrangement location B. An image tendency detection process, which is a process for detecting the image, is executed (step S13). Specifically, the master panel unit 2 transmits a control signal indicating that the image data information 44 </ b> F stored in the storage unit 44 is transmitted to the master panel unit 2 to the host computer 4. Receiving this control signal, the host computer 4 transmits image data information 44F to the master panel unit 2. The master panel unit 2 that has received the image data information 44F analyzes the image data information 44F, and sets a tendency level KL that is a value indicating the tendency of the brightness of the image for each placement location B.
The tendency level KL will be described in detail. In this embodiment, the tendency level KL includes a red tendency level RKL, a green tendency level GKL, and a blue tendency level BKL. The red tendency level RKL is a value indicating the tendency of the red component of the image displayed by the display unit 5 arranged in one arrangement place B. Compared with the other arrangement places B, the red tendency level RKL is large. The value “A” is set when there is a tendency to display the image including the image, or the image including the red component is frequently displayed. Otherwise, the value “B” is set. . Similarly, the green tendency level GKL is a value indicating the tendency of the green component of the image displayed by the display unit 5 arranged at one arrangement location B, and the blue tendency level BKL is arranged at one arrangement location B. This is a value indicating the tendency of the blue component of the image displayed by the displayed display unit 5.

FIG. 11 is a diagram illustrating an example of a state in which the tendency level KL of each color is set for all the arrangement locations B by executing the image tendency detection process in step S13.
As shown in FIG. 11, after the image tendency detection process is executed, the tendency level KL of each color is set for all the arrangement locations B. For example, the location B at the lower left of the front (location number D = D01
), The value “B” is set as the red tendency level RKL, the value “A” is set as the green tendency level GKL, and the value “A” is set as the blue tendency level BKL.

Returning to FIG. 8, after executing the image tendency detection process of step S <b> 13, the master panel unit 2 is based on the deterioration level RL set for each display unit 5 and the tendency level KL set for each placement location B. Thus, for each display unit 5, an arrangement location B where the display unit 5 should be arranged
A suitable location B is identified (step S14). For example, the master panel unit 2 refers to the red deterioration level RRL set for each display unit 5, and specifies the display unit 5 that has deteriorated to such an extent that the luminance with respect to red is visually uncomfortable (example in FIG. 10). Then, panel unit 3 of ID = 08). Further, the master panel unit 2 is arranged at each location B
Referring to the red tendency level RKL set to, an arrangement location B that tends to not display an image having a red component is specified (in the example of FIG. 11, the arrangement location B of arrangement number D = D01). Then, as the placement location B suitable for the identified display unit 5, the identified placement location B
Determine. This is because, when the specified display unit 5 is arranged at the specified arrangement location B, the display unit 5 displays an image containing a lot of red components or a frequency of displaying an image containing red components. This is because the deterioration of the luminance of the specified display unit 5 with respect to red becomes inconspicuous, thereby relieving the uncomfortable appearance due to the deterioration of luminance with respect to red.
Similarly, the master panel unit 2 has the green deterioration level GRL and the green tendency level GK.
Comparison result with L, Comparison result between blue deterioration level BRL and blue tendency level BKL, and combination with red deterioration level RRL, green deterioration level GRL and blue deterioration level BRL, red tendency level RKL, green tendency level GKL And the suitable arrangement | positioning place B of each display unit 5 is specified based on the comparison result with the combination with blue tendency level BKL.

In the image tendency detection process described above, the tendency of the brightness of the image is detected. However, when the image displayed by each display unit 5 is a moving image, the master panel unit 2 determines the tendency of the brightness of the image. In addition, the tendency of the movement of the image may be detected. In step S14, when the arrangement location B suitable for the display unit 5 is specified, the deterioration level RL
In addition to the tendency level KL, the movement tendency of the image may be used. According to this configuration, by using the tendency of image movement when specifying a suitable placement location B, the placement location B suitable for the display unit 5 that displays a moving image can be suitably specified.
In the image tendency detection process, the master panel unit 2 sets the tendency level KL for each arrangement location B. For example, by analyzing the image data information 44F, the red color of the image displayed by the display unit 5 is displayed. , Placement location B in the order of the trend of each color component of green and blue
May be ranked. According to this, when specifying the arrangement location B suitable for each display unit 5 in step S14, the master panel unit 2 refers to the above-mentioned order, whereby the arrangement location B of the display unit 5 whose luminance is deteriorated. It is possible to easily specify a suitable placement location B.
In addition, when all the placement locations B display images having almost the same color components, and the placement location B suitable for the identified display unit 5 cannot be identified even with reference to the tendency level KL, Arrangement location B (panel arrangement information 44 in FIG.
In the example of B, it is specified as a suitable placement location B from the placement location B close to the placement number D = D01). This is because, when a person views the display device 10 from the front, the image displayed on the display unit 5 arranged at the lower left tends to have the least line of sight.

After specifying an appropriate location B for each display unit 5 in step S14, the master panel unit 2 transmits information to that effect to the host computer 4 (step S15).
). The host computer 4 that has received the information can execute, for example, the following processing based on this information.
For example, the host computer 4 can display the arrangement location B suitable for each display unit 5 on the display unit 46 by a list or the like. According to this, the worker can quickly and easily recognize a suitable arrangement location B for each display unit 5 by referring to the display unit 46. And when an operator arrange | positions the display unit 5 in the suitable arrangement | positioning place B based on this recognition, as mentioned above, even if it is a case where the display unit 5 has deteriorated to the extent that it feels strange, This uncomfortable appearance can be alleviated. In particular, when the display unit 5 has deteriorated to the extent that it needs to be repaired or needs to be replaced with a new display unit 5, conventionally, an uncomfortable appearance will occur until these are repaired or replaced. The image was displayed in the state. However, even if the display unit 5 has deteriorated to the extent that repair or replacement is necessary, discomfort in appearance can be quickly alleviated by arranging the display unit 5 in a suitable arrangement location B. Until the repair or replacement is performed, the image is displayed in a state where the uncomfortable appearance is alleviated.

Further, for example, the host computer 4 displays on the display unit 46 a pseudo display of the state of the image P when one image P is displayed on the display device 10 in the current arrangement of the display units 5.
Based on the received information, the state of the image P when the one image P is displayed on the display device 10 when the display unit 5 is arranged at a suitable arrangement location B can be displayed in a pseudo manner. According to this, the operator can recognize how the display state of the display device 10 changes when the display unit 5 is arranged at a suitable arrangement location B by referring to the display unit 46. Therefore, it can be suitably determined whether or not to actually arrange.
In addition, for example, the host computer 4 controls the master panel unit 2, and among the display units 5, those specified as the display units 5 that have deteriorated to such an extent that they feel uncomfortable by the processing in step S <b> 14 in FIG. A message to that effect is displayed on the display panels 27 and 37, and a message to that effect is displayed on the display panels 27 and 37 of the display unit 5 that is currently arranged at the arrangement location B specified as the arrangement location B suitable for the display unit 5. You may make it do. According to this, the operator can quickly recognize the deteriorated display unit 5 and the placement location B suitable for the display unit 5, and can quickly perform the work of placing the display unit 5 in the suitable placement location B. And facilitation can be achieved.

Further, for example, when the host computer 4 acquires that there is the display unit 5 whose luminance has deteriorated to such an extent that the user feels uncomfortable with the received information, the host computer 4 displays a warning to that effect, The unit 49 can emit a sound to that effect, or send an e-mail to a worker's e-mail address registered in advance. According to this, the operator can recognize that there is the display unit 5 whose luminance has deteriorated to such an extent that the user feels a sense of discomfort quickly.

The arrangement location specifying process shown in FIG. 8 may be started by transmitting control information from the host computer 4 to the master panel unit 2 and the panel unit 3.
The master panel unit 2 and the panel unit 3 may start processing once a day at a preset time, or the processing may be started when the display device 10 is activated. Further, for example, when the operator looks at the display device 10 and notices the deterioration of the display unit 5 or when the operator feels something strange about the display state of the display device 10, the worker You may make it start by operating the input part 45. FIG.

As described above, according to the present embodiment, each display unit 5 is based on the deterioration level RL set for each display unit 5 and the tendency level KL set for each placement location B.
A location B suitable for the above is specified. Here, as described above, when one display unit 5 is arranged in the arrangement location B specified as the arrangement location B suitable for the display unit 5, the deterioration of the luminance of the display unit 5 becomes inconspicuous. For this reason, for example, even when the display unit 5 is deteriorated and an uncomfortable appearance appears in the displayed image, the discomfort can be quickly alleviated by arranging the display unit 5 in the specified arrangement location B. can do.
Further, according to the present embodiment, the deterioration level RL is detected based on the luminance of the display unit 5, and the tendency level KL is detected based on the luminance of the image for each placement location B. Therefore, the arrangement location B specified based on the deterioration level RL and the tendency level KL is specified in consideration of the luminance of the display unit 5 and the luminance of the image for each arrangement location B. For this reason, the display unit 5 is placed in the specified arrangement place B even when the display image 5 is not matched with the other display units 5 and the displayed image is uncomfortable. The discomfort can be quickly relieved by the arrangement.

In addition, according to the present embodiment, the deterioration level RL is detected based on the luminance of the display unit 5 for red, green, and blue, and the tendency level KL is the luminance for red, green, and blue of the image for each placement location B. Is detected based on Therefore, the arrangement location B specified based on the deterioration level RL and the tendency level KL takes into consideration the luminance of the display unit 5 for red, green, and blue and the luminance of the image for each arrangement location B for red, green, and blue. Will be identified. For this reason, the display unit 5 is specified even when the displayed image has a strange appearance due to the brightness of the display unit 5 with respect to red, green, or blue not matching that of the other display units 5. The discomfort can be quickly alleviated by arranging in the arranged location B.
In addition, according to the present embodiment, the master panel unit 2 detects the display unit 5 that is deteriorated so that the appearance of the displayed image is uncomfortable by referring to the deterioration level RL of each color, and this display unit 5 is specified. For this reason, the display unit 5 is specified even when the display image 5 is uncomfortable due to the deterioration of the display unit 5 that has deteriorated to such an extent that the display image looks uncomfortable. The discomfort can be quickly alleviated by arranging the arrangement place B.

Further, according to the present embodiment, in the image tendency detection process in step S13 of FIG. 8, by analyzing the image data information 44F, the red, green and blue color components of the image displayed by the display unit 5 are analyzed. The placement location B can also be ranked in order of the trend. According to this, when specifying the arrangement location B suitable for each display unit 5 in step S14, the master panel unit 2 refers to the above-mentioned order, whereby the arrangement location B of the display unit 5 whose luminance is deteriorated. It is possible to easily specify a suitable placement location B.
Further, in the present embodiment, as described above, in the image tendency detection process in step S13 of FIG. 8, the tendency of the luminance of the image is detected, but the image displayed by each display unit 5 is a moving image. In addition, the master panel unit 2 may detect not only the luminance tendency of the image but also the movement tendency of the image. Then, when specifying the arrangement location B suitable for the display unit 5 in step S14 of FIG. 8, not only the deterioration level RL and the tendency level KL but also the tendency of the movement of the image may be used. According to this configuration, by using the tendency of image movement when specifying the placement location B, the master panel unit 2 suitably specifies the placement location B suitable for the display unit 5 that displays a moving image. be able to.

Further, in the present embodiment, the host computer 4 that has received the information regarding the placement location B suitable for each display unit 5 can display the placement location B suitable for each display unit 5 on the display unit 46 using a list or the like. it can. According to this, the operator can quickly and easily recognize the suitable arrangement location B for each display unit 5 by referring to the display unit 46, and based on this recognition, the operator can actually select the display unit 5 appropriately. It becomes possible to arrange at the arrangement location B. And when an operator arrange | positions the display unit 5 in the suitable arrangement | positioning place B based on this recognition, as mentioned above, even if it is a case where the display unit 5 has deteriorated to the extent that it feels strange, This uncomfortable appearance can be alleviated. In particular, when the display unit 5 has deteriorated to the extent that it needs to be repaired or needs to be replaced with a new display unit 5, conventionally, an uncomfortable appearance will occur until these are repaired or replaced. The image was displayed in the state. However, even if the display unit 5 has deteriorated to the extent that repair or replacement is necessary, discomfort in appearance can be quickly alleviated by arranging the display unit 5 in a suitable arrangement location B. Until the repair or replacement is performed, the image is displayed in a state where the uncomfortable appearance is alleviated.

In addition, the said embodiment shows the one aspect | mode of this invention to the last, and a deformation | transformation and application are arbitrarily possible within the scope of the present invention.
For example, in the above embodiment, the image data information 44F is obtained by associating the image data transmitted to each display unit 5 in the last 30 minutes for each arrangement location B with the arrangement number D for each arrangement location B. However, the time for storing the image data information 44F may be arbitrarily designed according to the storage capacity of the storage unit 44. The image data information 44F is not image data itself,
It may be data relating to the brightness of the image data, data relating to the color depth of the image data, or the like.
According to this, it is not necessary to analyze the image data itself when detecting the display tendency for each arrangement location B in step S13 of FIG. 8, and the processing time can be shortened.

In the above-described embodiment, the deterioration level RL is obtained for each display unit 5 based on the luminance deterioration for each color of red, green, and blue. However, the deterioration level RL is further obtained based on the luminance deterioration for white. It may be. In this case, step S1 in FIG.
In the image tendency detection process 3, not only the tendency level KL for each color of red, green, and blue, but also the tendency of the luminance with respect to the entire color of the image displayed by the display unit 5 arranged at each arrangement place B is shown for each arrangement place B. The tendency level KL for the entire color may be obtained. Here, when the white deterioration level RL is obtained, white is displayed on the entire surface of the display panels 27 and 37 in the deterioration state detection process, which is a state in which all the display bodies are colored. Therefore, if the current consumption is measured in this state and the deterioration state is detected based on the current consumption, the deterioration of the entire color of each display unit 5 can be detected. Then, by specifying the arrangement location B suitable for the display unit 5 based on the comparison result between the white deterioration level RL and the tendency level KL for the entire color, the luminance for the entire color deteriorates to such an extent that it feels strange. Even when the display unit 5 is present, the discomfort of the appearance can be quickly alleviated by arranging the display unit 5 in the arrangement location B suitable for the display unit 5.

Further, only the deterioration level RL for white is obtained in the deterioration state detection process of step S12 in FIG. 8, and only the tendency level KL for the entire color is obtained in the image tendency detection process of step S13. The arrangement location B suitable for each display unit 5 may be specified by the RL and the tendency level KL for the entire color. According to this, when specifying the location B, the processing time can be shortened by not using the deterioration level RL and the tendency level KL of each color of red, green, and blue.
In the above embodiment, two values of “A” and “B” can be set as the deterioration level RL. However, the deterioration level RL may be set to a finer value. For example, although the display unit 5 is slightly deteriorated, it is necessary to replace the value “C” indicating that the deterioration does not proceed to such an extent that the display unit 5 feels uncomfortable or to be immediately replaced with a new display unit 5 and repaired. A value “D” or the like indicating the presence may be set. The same can be said for the tendency level KL.
According to this, the information that can be acquired by the worker increases, and the choices of actions that the worker can take can be increased. For example, the worker arranges the display unit 5 in a suitable arrangement location B only when there is a display unit 5 that needs to be replaced or repaired, and alleviates the uncomfortable appearance until the replacement or repair is performed. You can take actions such as

Moreover, in the said embodiment, although the master panel unit 2 has detected the deterioration of the brightness | luminance with respect to the color of each display unit 5 in deterioration state detection process S12 of FIG.8 S12, in that case, the HLS of a display body is detected. You may make it detect luminance degradation by a color space.
