Description of the Invention: [Technical Field] The present invention is an image correction data generation system, an image correction data generation method, an image correction data generation program, and an image correction circuit that efficiently suppress display unevenness. [Prior Art] Nowadays, a manufacturing line for displaying a liquid crystal panel or the like is constructed in order to achieve uniform quality. However, even in such a (four) shot, there is a difference in the display of the persimmon display at the time of manufacture. Therefore, 1 adjusts the display and outputs a better image, and has carried out various kinds of discussions (for example, the reference to the literature. The technique described in the special offer is based on the quality of the image. The quality of the display is adjusted to approximate the image quality of the target (or reference) display. For this purpose, the control unit of the image quality adjustment device includes: a target display; and a data storage unit for adjusting characteristic data of the target display. The department calculates the Gamma whitebaiance conversion data based on the data of the data memory department, and makes the conversion gamma adjuster. _, the measurement department uses the data memory and gamma white Balance the conversion data to calculate the color management set color data (color manage with t set profile data), and keep the corridor data in the color management adjuster. Also 'display sometimes uneven display phenomenon. This kind of The display is uneven, depending on the brightness of the plurality of pixels (pixel) slightly, the Xiaoke contains uneven brightness and uneven color. Also 'uneven brightness and uneven color. And the simultaneous occurrence of both parties. Therefore, some people have reviewed the removal of brightness unevenness caused by the integrator optical system while correcting the color unevenness of the liquid crystal panel, so as to obtain a high-quality projection image of 201239870. A projector for use in a quality (for example, refer to Patent Document 2). The technique disclosed in the patent document 2 is based on the color unevenness correction LUT data obtained by the camera for measuring the unevenness of the color. Adding brightness shading to the brightness unevenness correction LUT data generated by the known brightness unevenness measuring camera, thereby generating a two-dimensional color in the horizontal/vertical direction of the liquid crystal panel corrected according to the illuminance level of the input image signal. Unevenness and brightness unevenness display unevenness correction lut data. The display unevenness correction data of the LUT memorized in the liquid crystal projector device is used to correct two-dimensional color unevenness and uneven brightness and convert into equal images. [Prior Art Document] [Patent Document 1] Japanese Patent No. 4109702 [Patent Document 2] JP-A-2006-153914 (Invention) 】 (The problem to be solved by the invention) When inputting a completely flat image (all pixels are the same value) to the display, it is desirable to output a completely flat impurity. However, the brightness of the image is slightly different. This difference will show a slight axis. This kind of display will happen on the LCD panel because it depends on the unit _ (correction of the gamma, or the brightness distribution of the backlight. Moreover, in the - law When these display unevenness is removed, a problem may occur. That is, the liquid crystal itself due to the cell gap is not more than 1%, and most of the liquid crystal is only about 398201239870, which is relative to the 'backlight source'. When the peripheral dimming (limbdarkening) is more, it is about 3 (10). When correcting such display unevenness, since the data value of the complete white (career gray) image cannot be corrected, the correction (4) is bright, so the data value of the completely white (four) image can only be corrected to the negative side. Therefore, when the correction is performed to remove the unevenness of the display, the brightness of the vicinity of the center of the towel is lowered by the influence of the surrounding of the liquid crystal panel, that is, the brightness of the panel is also 30%. reduce. Also, when correcting for individual displays, it is expected to be corrected as efficiently as possible. SUMMARY OF THE INVENTION An object of the present invention is to provide an image correction data generation system, an image correction data generation method, an image correction data generation program, and an image correction circuit which can effectively suppress display unevenness. The means for solving the problem is to obtain output image data from the imaging unit. In order to achieve the above object, a video correction data generating system according to a first aspect of the present invention includes a signal generating unit, an imaging unit, and a control unit. The signal generating unit supplies the 彳5 number that outputs the I image to the display panel to feed the imaging unit, and captures the image on the display.

In the present embodiment, it is assumed that the display unevenness (brightness unevenness) of the display panel to be adjusted is suppressed and the quality of the enamel is improved. Further, in the present embodiment, the liquid crystal panel 10 is used as the display panel to be adjusted. The liquid crystal panel 10' includes a liquid crystal (liquid crystal portion) sandwiched between the transparent electrodes and a backlight for illuminating the liquid crystal from the back surface. In the liquid crystal panel 1Q, the liquid crystal panel is outputted unevenly, and the periphery of the backlight is dimmed. Overlapping images. In order to improve the image quality of the liquid crystal panel 10, as shown in FIG. 3, a correction circuit 5 is used. The correction circuit 50 is provided with a non-volatile memory (ROM 51) for recording an image correction table. In the _51, the data on the correction value (image correction table) is recorded, and the correction value is used to adjust the signal value of the input image signal. In the present embodiment, the plane distribution of the correction value is recorded for each of the reference gray scales. Then, as shown in FIG. 1, the image correction data generating system for calculating the correction value includes a enamel yarn setting 2G, a photographing photographic amount, a test pattern generating device 4A, and a writer 60. Here, as the imaging device of the imaging unit, the image displayed on the liquid crystal panel 1 is imaged, and the output image data is supplied to the quality adjustment device 2A. In the present embodiment, a monochrome camera equipped with a CCD element is used as the imaging camera. 201239870 The test pattern generating device 4' as the signal generating portion supplies a test pattern signal to the liquid crystal panel based on the image from the enamel adjusting device 20. In the present embodiment, an 8-bit (8-bit) RGB signal is supplied to the entire panel of the liquid crystal panel. The ROM writer 60 writes the correction value data output from the image quality adjusting device 20 to the ROM 51. The image quality adjusting device 20 is a computer terminal that performs processing for calculating a correction value for adjusting the image quality of the liquid crystal panel. The enamel adjusting device 20 includes a control unit 21. The control unit 21 includes a CPU, a RAM, a ROM, and the like, and performs processing (including a pointing phase for outputting a common signal value supply instruction, a video capturing phase, a band pass filtering processing phase, and a correction data generating phase). deal with). By executing the correction table generation program for this purpose, the control unit 21 functions as the process management unit 211 and the band pass filter unit 212 as shown in FIG. The process management unit 211 functions as an instruction unit, a video acquisition unit, and a correction data generation unit. Specifically, the process management unit 211 controls the signal input to the liquid crystal panel ι and performs a process of calculating the correction value based on the displayed image data displayed on the liquid crystal panel 1. The band pass filter unit 212' generates band-pass data for dividing the smooth change component and the thinner (four) component in the output image data acquired by the photographing camera 30, that is, the band pass chopper office 212 is divided into The fresh space between the shots is treated with a wave. (Revision data generation processing) Next, the correction data generation processing will be described using "Fig. 2". Here, an image correction 201239870 table for suppressing display unevenness for each predetermined gray scale is generated. Specifically, 'r ' is calculated for each gray scale (reference gray scale) set in advance, and the distribution of the correction value on the liquid crystal panel ίο is calculated. In the present embodiment, it is assumed that a reference gray scale of a pre-turn number (for example, ten stages) is used in a signal value represented by (four) t, and a gray scale corresponding to the reference gray__ object is sequentially changed for each turn phase, and in each- Adjust the object grayscale to produce an image correction table. First, the control unit 21 of the enamel adjusting device 20 executes the test pattern generation processing in step S1. Specifically, the process management unit 211 of the control unit 21 controls the test pattern generating device 40 to output an output of a signal for adjusting the output of the gray scale of the county. Here, in the gray scale of the adjustment target, the RGB signals (common signal values) having the same R signal value, G signal value, and B signal value are used for the entire liquid crystal panel. According to this instruction, the test pattern generating device 40 supplies an 8-bit RGB signal which is an adjustment target gray scale to the liquid crystal panel 1A. Then, the liquid μ panel 10 outputs a gray image of the gray scale of the adjustment target in accordance with the input of the RGB number. In this case, when there is unevenness in the cell gap in the liquid crystal or unevenness in brightness of the backlight, display unevenness in which the unevenness is superimposed on the liquid crystal panel 10 occurs. The camera 30 is photographed here to shoot an image in which unevenness has been superimposed. Then, the control unit 21 of the image quality adjusting device 20 executes the output image acquisition processing in step S2. Specifically, the process management unit 211 of the control unit 21 takes in the output image data obtained by capturing the liquid crystal panel 1 from the photographing camera 30. Then, the process management unit 211 converts the output video data into a luminance distribution ' of each block of the block composed of 8 × 8 pixels, and supplies it to the band pass filter and filter unit 212. Next, in step S3, the control unit 21 of the enamel adjusting device 2 executes the belt pass 11 201239870 skinning process ', and the body 5' axis portion 21 bandpass it wave H portion 212. The transmitted output meta-image data is subjected to bandpass chopping processing to calculate the bandpass data. The band pass material is composed of a frequency distribution in which the high frequency component and the low frequency are formed into a knife in accordance with the luminance distribution in the plane of the liquid crystal panel. Then, the band-passing vehicle department commits the bandpass data generated to the process management department. The control unit 21 of the human image quality adjusting device 20 executes the correction value calculation processing in step S4. Specifically, the management department of the Office of Control Office 21 has committed an image correction table in which the health information has been reversed. Further, the process management unit 2 ΐ , , , , , , , , , , , 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 基准 10 10 10 10 10 10 10 10 10 10 10 10 10 10 Then, the control unit 21 of the image quality adjusting device 2 performs the above-described processing in response to the gray scale of the next adjustment target. When the calculation of the correction data has been completed for all of the reference gray scales of all four, the control unit 2 of the image quality adjustment apparatus performs the 丽 write processing in step S5. Specifically, the process management unit 211' of the control unit 21 writes the temporarily restored video correction table to the leg. Thereby, at _51, the distribution of the correction value is recorded for the block position (xy coordinates) in the plane of the liquid crystal panel 1 for each-reference gray scale. (Image Display Processing) Then, the ROM 51 which is generated in response to the liquid crystal panel 10 is incorporated in the correction circuit 50. The correction circuit is a circuit for adjusting the image signal supplied to the liquid crystal panel 1 . Specifically, the image signal (RGB signal) for displaying the image on the liquid crystal panel 10 is supplied to the liquid crystal panel 10 and corrected together. Loop 50. 12 201239870 As shown in Fig. 3, the correction circuit 50 includes a selection interpolation unit 52 and an addition unit 53 in addition to the deletion. The interpolation unit 52 is selected to refer to the image correction table recorded in _ for each RGB signal. Here, the paste (four) 52, the two reference gray-like red scarfs of the 纟 龄 继 红 红 红 , , , , , , , , , , , 取得 取得 取得 取得 取得 取得 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 2χ4=8). Then, the 'interpolation unit' is linearly interpolated for the acquired correction value in accordance with the distance between the signal value of the video signal and each lattice point. Then, the adding unit 53 adds the correction value obtained from the selection interpolating unit 52 to the nozzle panel 1G of the image signal that is rotated, and acquires the corrected video signal to display the video. According to this embodiment, the following advantages can be obtained. In the present embodiment, the correction circuit 50 includes R_, a selection interpolation unit 52, and an addition unit 53. In the _51, the display is not touched in the image captured by the camera 3, and the image correction table is recorded. Since the display unevenness is different from the brightness of each pixel and the ideal value, "so that the difference from the ideal value of each pixel is measured in advance", it is possible to eliminate uneven display unevenness for each pixel by the correction according to the difference. . In the present embodiment, the smear 'in the RGM51' material is based on the map. The occurrence of unevenness is displayed, even if it is the same pixel, there is no certain input level. For example, a 19% gray pixel is displayed when 20% gray is input, sometimes changing by displaying 51% gray in 5〇% gray and 83% gray in 80% gray. Since the image correction table is recorded for each reference gray scale in 13 201239870 R0M51, correction corresponding to the signal value of each pixel can be performed. In the present embodiment, the image correction table is generated using the distribution after the band pass filter processing. Thereby, no correction is made for the gradual change in brightness. The liquid crystal itself is not 1/. The following is only about 5% even when there are a lot of them. On the other hand, when the backlight is dimmed to a large extent, there are about _days. It is assumed that when a complete white (1_gray) image is corrected without removing the side component (low cut: low cut), the surrounding dimming is affected, and the brightness near the center portion of the liquid crystal panel 10 is lowered. In this case, the smooth change in the amount of light of the entire screen is not easily detected by the human eye. Therefore, when the correction for not performing the low cut is performed, only the brightness of the liquid crystal panel 10 is lowered. Also, very fine display unevenness (high frequency components) is not easily detected by human eyes. Moreover, in order to correct very fine display unevenness, it is necessary to accurately obtain the position between the measurement image and the pixel position of the liquid crystal, and some micro offset offset manufacturing is uneven. Therefore, the image correction table can be easily and efficiently generated by performing high frequency component removal (high cut: high cut). Further, the above embodiment may be modified as follows. In the above embodiment, the monochrome unevenness is used to correct the unevenness in brightness. The display unevenness of the suppression object is limited to the brightness, and the above-mentioned implementation job can also be applied to the correction of color unevenness. When both the uneven brightness and the color unevenness are corrected, three RGB optical filters are used, and the output images are obtained in the imaging unit. Then, the correction value is calculated from the individual image by the above-described band pass filter processing (step S3) and correction value calculation processing (step 201239870 step S4). Then, three types of image correction tables for the R signal, the G signal, and the B signal are produced and recorded on the surface to correct the RGB data value of the input image, thereby suppressing color unevenness. In the above-mentioned implementation of the Lai towel, the various letters of the red and the red are made into images, and the brightness unevenness is corrected. When the color unevenness is corrected, instead of using the chopper, the single-color R signal, the G signal, and the B signal are separately supplied to the liquid crystal panel 1 and processed by the output image (step S2). The band pass filter processing (step s3) and the correction value calculation processing (step S4) generate an image correction table. Although the above-described image forming has been applied to the suppression of display unevenness of the liquid crystal panel 1G, the panel for adjusting the age of the object is not Weiding. The image correction of the present invention can also be applied to an output device such as an electric surface display H (PDP) or a sputum type. In the above-described embodiment, the test pattern generation portion g is executed for each of the liquid crystal panels 1 to be adjusted (step (1) to _ writer processing (step (6). Instead, in the representative display panel of the adjustment target, The representative correction value can be calculated by executing the test pattern generation processing (step S1) to the correction value calculation processing (step S4). Then, in this modified example, the representative correction value of the written person can also be created. In other words, in the representative liquid crystal panel, when the correction of luminance unevenness (display unevenness) caused by the light source (backlight) is performed, the above-described modification can be applied. In the process of reducing the number of backlights, or to turn the diffuser, or shorten the distance between the diffuser and the bulb, 'the brightness code caused by the backlight will occur. So avoid the uneven brightness of the liquid crystal panel caused by the back wire' It is possible to suppress the unevenness of the display by the above-mentioned modified example. In the case of the number of the lamps of the light bulb, etc., the number of components constituting the display panel can be reduced, and the cost can be reduced. Create a high-quality display panel. In addition, when the light bulb is removed, the amount of light from the light source will be reduced, but the distance between the bulb and the diffuser can be reduced by turning the optical sheet or the like. Adjusting the amount of light—while maintaining equal brightness. Moreover, the image correction of the present invention can be individually applied to each panel for such a representative correction value. New' performs the ray write processing for each correction value. In the case of 'the side can be suppressed according to the characteristics of the side board, and the high-quality display panel can be manufactured. That is, the correction of the big # is performed by representative image correction, and then for each - Fig. 1 is a schematic diagram of an image correction data generating system according to an embodiment of the present invention.
