Maximum pixel English name is Maximum Pixels, the so-called maximum pixel is obtained after interpolation operation. The interpolation operation is added to the image to increase the image amplification after the image is enlarged in the image by an operation method, a linear interpolation such as an image amplification, a linear interpolation such as a DSP chip is required to enlarge the image. The image quality obtained after interpolation operation cannot be compared to an image of the true photosensitive imaging. On the market, some merchants will indicate that "hardware interpolation is up to XXX pixels", which is also the same principle, but only on the quality and sensitivity of the image, the sharpness of the picture captured by the maximum pixel is not more than effective pixels. taking pictures. Maximum pixels, also directly refer to the pixels of the CCD / CMOS photoreceptor, some merchants in order to increase the sales, only the maximum pixels of digital cameras, in order to set the picture resolution in digital cameras, independently, the resolution picture of the highest pixel, However, the user is clear, this is the value derived from the internal operation of the digital camera, and when printing pictures, the loss of its image quality will be very obvious. So when you purchase a digital camera, it is most important to see the effective pixels. In addition, the pixels are also related to the output of the digital photo.
