Selected Topics-0044_Development of Image Signal Processors and Computational Photography and Progress in Overcoming Physical Limitations of Smartphone Cameras
Today, using smartphones to take photos has become a popular way for people to record and share everyday memories. Camera performance has also become an important factor for consumers when deciding to purchase a new smartphone. However, unlike traditional digital single-lens reflex cameras (DSLRs), smartphones are designed to be lightweight and slim. Therefore, adopting a larger CMOS image sensor (CIS) or a heavier lens assembly to improve photoshoot is not practical. To overcome this physical limitation, advanced image signal processors (ISPs) and innovative computational photography algorithms are used to significantly enhance the imaging quality of smartphone cameras. These solutions can effectively compensate for the shortcoming of not being able to incorporate larger optical components into a smartphone camera.
