The pixels of a digital camera are the most important indicators for measuring digital cameras . Pixel refers to the resolution of a digital camera . How many megapixels in a digital camera specification refers to the resolution of the CCD . The CCD is a light-sensitive semiconductor chip used to capture graphics and is widely used in scanners, copiers, and filmless cameras. Similar to the principle of film, light passes through a lens and projects graphic information onto the CCD .
The CCD pixel is the main performance indicator of the CCD. It determines the clarity of the displayed image. The higher the resolution, the better the image detail. The CCD is composed of area array photosensitive elements, each of which is called a pixel. The more pixels, the clearer the image.
Since the CCD image sensor contains more transistors, that is, the more pixels, the resolution of the CCD is higher; the larger the size of a single pixel, the higher the sensitivity of the CCD. Compared with JVC, JVC is an analog camera. The resolution, sensitivity and image quality are not comparable to CCD.
Digital cameras and cameras do not have a clear concept. They are just a popular saying in the civilian market. Strictly speaking, the imaging devices of the two are the same, but the back-end output and processing methods are different. For example, JVC's resolution indicator is "TV line", the traditional closed-circuit television system. There are a lot of detailed comparisons. In general, digital output cameras have higher resolution than analog output cameras (such as JVC) (on the premise of equivalent pixels)
With the development of technology, the spatial resolution of industrial and research-grade digital cameras is much higher than that of analog cameras. The analog camera has a maximum of 350,000 pixels, and the performance of digital cameras is far superior in terms of imaging accuracy, noise conditions and operability. Better than analog camera. In terms of color reproduction capability, high-performance analog cameras usually have better performance. For applications with higher color requirements, 3 CCD analog cameras can also be used , but such cameras are expensive.
