Smartphones have become the most accessible devices for everyday photography, allowing users to complete the entire process of shooting, editing, and sharing within a single device. I aim to enhance the photographic experience in mobile cameras by utilizing AI-based image processing technology. Traditionally, small cameras like those in smartphones had limitations in image quality and color reproduction due to the physical size of their lenses and sensors. However, modern smartphones are equipped with high computational power, enabling real-time complex image processing using AI. This allows even small cameras like smartphones to capture very beautiful photos. Furthermore, AI technology is bringing innovation to post-capture image editing. For example, by using image transformation techniques, it is possible to change the apparent material of an object captured in a photo to another material that aligns with the user's intent.
