What exactly is the difference between chromatic aberration and RGB?

Is there any difference in the effect?

Isn't it the same? Or RGB is a kind of color difference.,RGB only 3 interfaces, color difference is 3 and 5 points.,I don't understand much.,Consult together View the original post".

Chromatic aberration is a variant of RGB View original post

International Standard for Chromatic Difference Grades:

GB250 and GB251, divided into 5 grades, 5 grades for no color difference, generally first-class color difference requirements for 4 levels (including the middle, beginning and end) but and standard color contrast color difference has no standard requirements, depending on the supply and demand parties.

Allowable range of normal color aberration: Xiankai.

Very small or none, is the ideal match.

Medium Pena E: Tiny and is an acceptable match.

Tiny to medium, acceptable in some applications.

Medium, acceptable in specific applications.

There is a gap that is acceptable in the sale of undecided applications.

Above 0 E: Very large and unacceptable in most applications. <>

chromatic aberration (chromatic aberration; chromatic aberration): chromatic aberration, also known as chromatic aberration, is a serious defect of lens imaging, chromatic aberration is simply the difference in color, which occurs in the case of multichromatic light as the light source, monochromatic light does not produce chromatic aberration. The wavelength range of visible light is about 400 to 700 nanometers, and different wavelengths of light have different colors and different refractive indices when passing through the lens.

Chromatic aberration generally includes positional chromatic aberration and magnification chromatic aberration. Positional chromatic aberration makes the image obscured by stains or halos when viewed from any position, while magnification chromatic aberration makes the image have colored edges. The most important function of the optical system is achromatic.

Different wavelengths of light will be dispersed to varying degrees. White light is dispersed into various wavelengths of light in the ultraviolet, visible, and infrared wavelengths, and the image formed when it passes through the lens has color edges, which is chromatic aberration. The difference between the actual imaging of an optical system and the ideal imaging is collectively referred to as aberration.

Chromatic aberration is one of the aberrations, which is caused by the different transmittance of the transmitting material with different wavelengths, so it is only visible to multichromatic light. A combination of concave-convex mirrors made of different glass materials can eliminate chromatic aberrations. Quantitatively expressed differences in color perception.

It is expressed in terms of the difference in the three color attributes: lightness, hue, and saturation. Difference in lightness indicates a difference in shade, difference in hue indicates a difference in hue (i.e., reddish or bluish, etc.), and difference in chroma indicates a difference in vividness. The evaluation of color difference is very important in industry and commerce, and is mainly used in color matching in production and color quality control of products.

Modern chromatic aberration is based on the standard chromatic aberration formula recommended by the International Illuminating Association (CIE) and is calculated using instrumental and computer measurements, expressed in precise numbers. Commonly used such as CIE 1976L*A*B* and CIE 1976L*U*V* chromatic aberration formulas. The phenomenon of dyeing the same color leather, the color inconsistency between the batches, or the phenomenon of several color differences between the same drum and the same dyed leather is called color difference.

Suede, in particular, is more prone to color differences. It can refer to the color difference between different parts of the same leather, or the color difference between the same batch of processed leather, or the color difference between different batches of leather originally dyed with the same color. ‍‍

The word chromatic difference is often used in the industry, and it is also widely used in our daily life, which means the difference in color, that is, after the image is taken, the difference in color between the image and the real thing, the difference between depth and lightness. Color difference is the color of two walnuts is inconsistent. Even walnuts of the same tree in the same year will have color difference, in addition to the reason of the shade skin, the walnut of a tree before and after the time of the tree, the time of peeling the green skin is different, the yin and yang side of the fruit, whether there is insect moth, etc., may cause color difference.

Walnuts with color difference are affected in terms of quality, but it will not affect the play. The lighter color difference can be plated after playing, and the very serious color difference is relatively laborious, some take several years to plate well, and some can't be plated.

Chromatic aberration simply refers to the phenomenon that the hue, brightness, and chroma of the painted film are different from the hue, brightness, and color of the standard board or the whole vehicle. There is a difference in color, which is called color difference, such as the common cloth color, the display shows pure white color, black color, with other colors, and the screen is blue, red or yellow, etc. When two colors are close but not identical, there is a color difference between the two colors.

It is the ** you see on the Internet or paper, and the actual color in front of you is not exactly the same, which is called color difference. Generally speaking, chromatic aberration is the deviation of the same color in the process of printing and dyeing or other color matching.

Inevitable chromatic aberration issues.

Optical materials have different refractive indices for various wavelengths of color light, and light of the same caliber and different colors have different intersection points with the optical axis after passing through the optical system. The intersection point of light rays and optical axes of different calibers and colors is also different.

Any image of the plane, the object point is like a colored diffuse spot.

The difference in imaging position and imaging size between various colored lights is called chromatic aberration.

It's the difference between the same color.
