Larger pixel imaging effect are not better for car black box

  We buy car dvr camera also easily walk into this myth, see pixels and wide-angle look at the parameters, while ignoring some of the information car dvr camcorder in other areas. Imaging quality and effectiveness are many decisions, not the higher pixel video shoot out more clearly.
  When we purchase car black box dvr usually see businesses are given "maximum pixel reach XXX" and "effective pixels XXX", these two words what is the difference?
  The so-called maximum pixel is obtained after interpolation. Interpolation by digital devices provided within DSP chip, when the need to enlarge the image by nearest neighbor interpolation method, linear interpolation and other operation methods, in the enlarged image after the image is added to increase the required pixel. After interpolation image quality can not be obtained as compared with the real image of photographic imaging. If you know little about digital zoom and optical zoom, it is very simple to understand.
   Effective pixels, to add a picture of the size, if there is no more light into the light-sensitive device, the only way is to increase the area of a single pixel, rather than the number of pixels to change the way, may affect the picture sharp intensity and clarity. Therefore, in the pixel area remains unchanged, a digital camera can get the most out of the picture pixels, that is effective pixels.
   So relatively speaking, should focus on the effective pixel digital camera to see how much the value of the decision is effective pixels key picture quality.
