Popular science: tell you what the contrast of the projector
When we buy projector products, in addition to resolution and projection brightness, there is a very common parameter, that is, the contrast of the projected picture. Many users may know a little bit about the picture contrast, but it may not be very accurate to ask them to specifically say what the contrast does. Today we will explain the relevant knowledge about the picture contrast.
First, the contrast introduction:
The contrast of the projected image is simply the ratio of black and white in the image, that is, the gradient from black to white. Generally speaking, the larger the contrast ratio, the more gradient levels from black to white, and the richer the color performance of the projector.
The effect of contrast
For home projectors, the contrast of the screen is a very important parameter, because the contrast has a great influence on the visual effect of the displayed screen. Generally speaking, the larger the contrast of the screen, the clearer and more striking the image, and the natural color of the projected screen will be The brighter and brighter it is; the smaller the contrast, the darker the picture will be, giving people the feeling of a layer of fog in front of them.
The role of picture contrast is more than that. High contrast has a great impact on the clarity, detail performance and gray level of the projected image, so everyone should not ignore the important parameter of contrast when purchasing projector products.
