As shown in fig. 2, the method for correcting chromatic aberration of a digital image capturing device and a screen S100 includes a method for correcting chromatic aberration of a digital image capturing device S200, which includes: providing a digital image capturing device to be corrected S12; providing a wavelength tunable single-wavelength standard spectrum S20; performing standard image capturing S30; generating an image capturing chromaticity correction parameter S40; and completing the digital camera calibration S50.
The digital image capturing device to be corrected and the display screen to be corrected are provided S10, which provides the digital image capturing device to be corrected 111 and the display screen to be corrected 115, and then the correction procedure is completed for subsequent use, so that the digital image capturing device can obtain standard image information and the display screen can complete standard image presentation. The digital image capturing device 111 to be calibrated may be a camera or a video camera.
When the chromatic aberration correction method S200 for the digital image capturing device is implemented, the digital image capturing device to be corrected S12 is provided only by the digital image capturing device to be corrected 111.
As shown in fig. 3, a wavelength tunable single-wavelength standard spectrum S20 is provided, which is a single-wavelength standard light source 20 for each single wavelength provided in time sequence and time division as a standard for calibration; the wavelength (λ n) of the single-wavelength standard light source 20 may be an integer value between 360nm and 830nm, and each single wavelength (λ n) has a set of standard gray-scale values (WR, Ln/WG, Ln/W B, Ln); wherein W represents gray scale; r is red, G is green, B is blue; ln represents wavelength and may be, for example, wavelength integer values from 360 to 830.
As shown in fig. 4A and 4B, the single-wavelength standard light source 20 can be provided by the light source 210, the controller 220 directly in a time-sharing manner under the control of time-sharing output, or the light source 210, such as an LED lamp, a xenon lamp, a high-pressure discharge lamp, a halogen lamp, a tungsten lamp, or a fluorescent lamp, in combination with the wavelength selector 230, such as a grating or a prism.
Performing a standard image capturing S30, which uses the digital image capturing device 111 to be corrected to capture images of the single-wavelength standard light source 20 according to the above time sequence, and at this time, generating image capturing gray-scale values (PR, Ln (x, y)/PG, Ln (x, y)/PB, Ln (x, y) of each pixel of each single-wavelength frame corresponding to each single-wavelength standard light source 20, where p (pixel) is a pixel, R is red, G is green, and B is blue, Ln represents a wavelength, and may be, for example, a wavelength integer value code from 360 to 830, and (x, y) represents a camera image capturing pixel coordinate, and then, for convenience of subsequent calculation, performing a chromaticity conversion calculation on the image capturing gray-scale values (PR, Ln (x, y)/PG, Ln (x, y)/PB, Ln (x, y)) of each pixel of each single-wavelength frame, and corresponding to each pixel chromaticity value (CLn (x, y) of each single-wavelength frame, y)); wherein C represents a chromaticity value; ln represents wavelength, which may be, for example, a wavelength integer value code number of 360 to 830; and (x, y) represents the image-taking pixel coordinates of the camera.
In practical operation, when the digital image capturing device 111 to be corrected performs one image capturing, one frame 112 is generated, and another frame 112 is composed of a plurality of pixels 113 (e.g. 1024 × 768 pixels), and each pixel may be composed of three sub-pixels 114 (e.g. three R/G/B sub-pixels); therefore, the image capture gray-scale values (PR, Ln (x, y)/PG, Ln (x, y)/PB, Ln (x, y)) of each pixel of each single-wavelength frame refer to image capture gray-scale values of a single pixel in the frame generated by each single wavelength, and 1024 × 768 image capture gray-scale values can be generated by taking the frame as an example, which is 1024 × 768 pixels.
The image capturing chromaticity correction parameters S40 are generated by performing a difference statistic operation on the image capturing chromaticity value (CLn (x, y)) of each single-wavelength frame after image capturing and the corresponding standard spectrum of the single wavelength to generate each single-wavelength image capturing chromaticity correction parameter.
Specifically, an image capturing chromaticity correction parameter S40 is generated, which is to perform difference statistical operation on the image capturing chromaticity value (CLn (x, y)) of each pixel of each single-wavelength image and the standard chromaticity value (SR, Ln (x, y)/SG, Ln (x, y)/SB, Ln (x, y)) of the single-wavelength standard light source 20 corresponding to the single wavelength after image capturing, and generate the total color difference value of each single wavelength as each single-wavelength image capturing chromaticity correction parameter; wherein S is expressed as a standard colorimetric value; ln represents wavelength, which may be, for example, a wavelength integer value code number of 360 to 830; and (x, y) represents the image-taking pixel coordinates of the camera.
More specifically, the step S50 of completing the calibration of the digital image capturing device is to linearly superimpose the actual image capturing spectrum and the corresponding total color difference value of each single wavelength, so as to dynamically complete the calibration of the digital image capturing device S50.

As shown in fig. 5B, in another case, the computing module 50 may be, for example, an embedded system 520 embedded in the digital image capturing device to be corrected 111, as shown in fig. 7A, at this time, the embedded system 520 may be used to generate the image capturing chromaticity correction parameter 410 in the digital image capturing device to be corrected 111 and then dynamically perform the real-time chromatic aberration correction on the digital image capturing device to be corrected 111.
After the step S200 of the chromatic aberration correction method of the digital image capturing apparatus is completed, the display screen 115 to be corrected is corrected.
As shown in fig. 6, a standard gray-scale signal S60 is inputted, which is a standard gray-scale signal 610 having R (0-255)/G (0-255)/B (0-255) inputted into the display screen 115 to be corrected, and the image generated on the display screen 115 to be corrected is the display screen 116 before correction.
Performing a front-screen calibration image capturing S70, which uses the calibrated standard digital image capturing device G111 to capture an image of the front-screen calibration display 116 to generate a front-screen calibration gray scale value (USR (x, y)/USG (x, y)/USB (x, y)); wherein US denotes a pre-correction screen gray scale; r is red, G is green, B is blue; (x, y) represents screen pixel coordinates; the USR (x, y)/USG (x, y)/USB (x, y) is between 0 and 255, and then the corrected front screen gray scale value (USR (x, y)/USG (x, y)/USB (x, y)) is subjected to chromaticity conversion calculation to correspond to the corrected front screen chromaticity value.
The screen chromaticity correction parameter S80 is generated by performing chromaticity conversion on the standard gray-scale signal, i.e., the standard gray-scale signal 610 with R (0-255)/G (0-255)/B (0-255) input to the display screen 115 to be corrected, and then calculating the chromaticity value of the screen before correction generated by the standard digital image capturing device G111, so as to generate the screen chromaticity correction parameter 810 shown in fig. 8.
The screen correction is completed S90, as shown in fig. 8, the image chromaticity correction parameter 410 and the screen chromaticity correction parameter 810 are synthesized into a system correction parameter 910, and written into the color Profile 115a of the display screen, such as an ICC Profile (i.e., ICC color Profile).
