    This paper introduces the technological evolution of a smartphone camera that challenges the interchangeable lens type 35 mm full-frame camera.

    For smartphone cameras, it is necessary to realize high-sensitivity imaging with a very small CMOS Image Sensor, a telephoto lens and a zoom function in a flat housing. These are realized by a new color imaging method, a periscope lens, a multi-camera configuration and high-performance computing technology. We will explain specific examples of such technological evolution, and as the goal, we will clarify the comparison result between the latest smartphone and 35mm FF camera with the image quality evaluation data of DXOMARK.
