DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A monitor brightness adjusting system according to the present invention will be described in detail below in accordance with an embodiment.

As shown in FIG. 1 (a), the system of the present invention is output and displayed on the display screens of two or more monitors 1 provided with an electronic image output display screen of a liquid crystal display type or a CRT display type. This is a brightness adjustment system for matching the brightness (including the hue) of the image to the same brightness (including the hue).

In this system, as shown in FIG. 1A, a reference print 11 which is referred to when comparing and adjusting the brightness (hereinafter referred to as brightness) of a monitor is prepared. The reference printed matter 11 has an image 1 for which the brightness can be easily distinguished visually.
It is desirable that 3 selects a printed material printed on the printing sheet 12. For example, it is desirable to use an image such as a gray system in which the density of a color is easy to understand.

The operation of adjusting the monitor brightness by the monitor brightness adjustment system of the present invention will be described below with reference to the front views of FIGS. 1A and 1B and the system flowchart of FIG.

S1 (Step 1): First, an image 13 whose brightness is easily distinguished visually is selected and printed on a print sheet 12, and a reference printed material 11 (referred to when comparing and adjusting the brightness) is referred to. 1 (a)) is prepared.

S2 (Step 2): Next, among several monitors 1 (see FIG. 1 (a)) for adjusting the brightness (including the hue) to be the same, the reference is used. One monitor is selected as a reference monitor.

S3 (Step 3): Next, the reference monitor 1
The image 3 having the same content as the image 13 of the reference printed material 11 is output and displayed on the screen 2 of FIG.

S4 (Step 4): Next, the R, G, and B output adjustment units (dial or adjustment slide) of the reference monitor 1 are adjusted to adjust the brightness of the image 3 output and displayed on the reference monitor 1; R (red) value, G (green) value,
The hue is adjusted by changing the B (blue) value so that the image 3 that is output and displayed is viewed with the same brightness and hue as the image 13 of the reference print 11.

S5 (Step 5): R (red) value obtained by adjusting the brightness and hue of the reference monitor 1,
The G (green) value and the B (blue) value are recorded and transmitted as data by the transmission means. The transmission means may be, for example, a manual transmission method of manually writing and recording on a recording sheet and transmitting the data, or data to be output and recorded on an output sheet using a data output means (such as a printer output machine). There is an output method, or a recording transmission method using a recording medium that stores and reproduces and outputs an electric storage medium such as a computer memory, a magnetic recording medium, and a magneto-optical medium.

S6 (Step 6): Next, each of the other monitors 2 to be adjusted shown in FIG.
On the screen 22, 1, 21, 21,..., Images 23, 23, 23,
... is output and displayed.

S7 (step 7): Next, the R (red) of the image obtained and recorded by the brightness adjustment and the hue adjustment of the reference monitor 1 is applied to each of the other monitors 21, 21, 21,. ), G (green), and B (blue) values, for example, in the same manner as in the input / output related diagram shown in FIG.

S8 (step 8): Next, the other monitors 21, 21, to which the R, G, B values of the reference monitor 1 are assigned,
The output display images 23, 23, 23 of 21,.
... and the printed image 13 of the reference print 11
Are visually compared with each other, and output display images 23, 2
, R, G, B output adjustment units of the other monitors 21, 21, 21,... So that the brightness and the hue of 3, 23. By operating 24 (dial or adjustment slide), the R, G, and B values are finely adjusted to adjust the hue.

FIG. 3 shows a reference monitor 1 and other monitors 2.
The relationship between the adjustment input value A by the R, G, B output adjustment unit for adjusting the brightness and hue of 1, 21, 21,... And the image output value B (brightness, hue) of the output display image. The broken line graph L1 and the solid line graph L2 are graphs before and after adjustment, respectively.

As described above, according to the present system, one of the plurality of monitors 1 shown in FIG. 1A is selected as the reference monitor 1 and is output and displayed on the display screen 2 of the selected reference monitor 1. After adjusting the R, G, and B values of the reference monitor 1 so that the image 3 and the printed image 13 of the reference printed material 11 can be viewed with the same brightness and hue, the reference monitor at the stage where the same brightness and hue appear. , R, G, B values of the other monitors 21, 21, 21,...
The brightness and the hue of the image 23 output and displayed on the screen 22 of each of the other monitors 21, 21, 21,... Shown in FIG.
By adjusting the brightness and the hue of the image 13 to be the same as each other, each monitor 1 and each other monitor 21 are adjusted.
Can be adjusted.

[0020]

According to the system of the present invention, the adjustment of the brightness of the images on a plurality of monitor screens can be realized at low cost without using an expensive colorimeter, and even in a remote environment. This has the effect of enabling the brightness of the image to be adjusted.
