We all use dual-camera phones. Does it really affect the quality of taking pictures?

Hello! Dual cameras have a great influence on the quality of taking pictures. The dual cameras installed on the mobile phone can provide different shooting functions for the mobile phone by adopting different schemes. At present, three popular dual-camera schemes, namely "color+black and white", "imaging+depth of field" and "wide angle+telephoto", provide mobile phones with image enhancement, shallow depth of field and double optical zoom effects respectively. In addition, there is a naked-eye 3D scheme, but this scheme is not adopted until there is a smart phone for the time being.
