Camera Resolution Definition:
4K resolution. 4K resolution means that the value of each line in the horizontal direction is 4096 pixels or closer, regardless of the image ratio. Of course, this is not the only definite pixel ratio, such as 4096× 3112, 3656× 2664, 3840× 2160 all belong to the category of 4K resolution. The APP resolution of WiFi network camera is generally interpolated resolution, and the image of the video screen display is changed through software. Its own resolution is related to the video recording, that is, the resolution of the hardware.
2k resolution. 2K resolution is a general industry term that refers to the horizontal resolution of the screen or content reaching about 2048 pixels, compared to the traditional 2K resolution of 2048×1080. 2048× 1080, 1998×1080, 2048×858, these three rates can also be 2K resolution. Compared to 4k resolution, the resolution of 2K resolution is about half lower.
1080P resolution. The frame rate is usually 30 frames, which can be represented after p, such as 1080p30 frames, which means that there are 30 frames in one second of image. The resolution of 1080P is generally expressed as 1920*1080, and P is the frame rate. 1080P is the mainstream resolution in the market, and the hardware resolution can reach 1080P, so the effect is already superb. In the case of CCD sensors, the effect is clearer.
720P resolution. 720P is a display format that reaches a resolution of 1280×720 under progressive scan. It is the fusion of digital cinema imaging technology and computer technology. 720P and 1080P are the most popular resolutions, and the frame rate generally corresponds to 30, that is, 30 photos are delivered per second, thus forming a video image. The hardware recording resolution of the network WiFi camera is 1280*720, which is 720P.
Pixels of the camera module:
First of all, let's talk about the current commonly used pixels of camera modules are: 30W/100W/200W/500W/800W/1300W/1600W, which is the commonly used pixel value, and the corresponding rates are 300,000-640*480,1 million-1280*720,2 million-1920*1080,5 million-2592*1944,8 million-3200*2400,13 million-4208* 3120,16 million-4928*3264, the above is just the size of the standard resolution.
Ordinary DVP/MIPI interfaces can generally be applied according to the driver software of the chip to select the largest pixel and the following pixels, simply put, 16 million theoretically supports all the following pixel applications. The USB camera module can be debugged according to customer requirements, and a variety of supported resolutions are compatible with the resolution of all pixels of 16 million and below.
Finally, it is necessary to warm the reminder that the corresponding products and applications should choose the right products to do, and you can't just look at the price or rely on imagination to make a decision, after all, even if a size 36 foot can wear a size 40 shoes, it will be uncomfortable, and on the contrary, a size 40 foot can not wear a size 36 shoes. The release of each chip will correspond to a certain field of application, if you lack professional knowledge in this area, you still have to find a professional camera module manufacturer to recommend the answer, and then select the right product.
