影像讯号处理器和计算摄影的发展以及克服智慧型手机相机的物理限制方面的进展

如今，使用智慧型手机拍照已成为人们记录和分享日常记忆的常见方式。 相机性能也是消费者决定购买新智慧型手机时的重要因素。 然而，与传统的数位单眼相机（DSLR）不同，智慧型手机的设计目标是轻薄。 因此，使用大型CMOS影像感测器（CIS）或笨重的附加镜头来提高拍摄性能是不切实际的。 为了克服这一物理限制，先进的影像讯号处理器 (ISP) 和创新的计算摄影演算法被用来显着提高智慧型手机相机的影像品质。 这些解决方案可以有效弥补无法将更大的光学元件整合到智慧型手机相机的问题。

在本报告中，我们分析了智慧型手机相机的ISP和计算摄影的发展和普及趋势，并讨论了智慧型手机相机面临的问题、如何解决以及未来技术发展和市场成长的方向。我们将编译并提供信息，例如：

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.
