Backlight also knows what this advertisement is.

With regard to the vivo X series mobile phones, I believe that everyone is familiar with the advertising word "clear backlight, illuminate your beauty", which is the vivo X20 series mobile phone. This mobile phone is equipped with a self-customized DSP chip, which was unique in the mobile phone circle at that time. Based on the chip and the super HDR algorithm, it solves many pain points of users when shooting backlight scenes, and has won unanimous praise.
