Patent number: 10313636Abstract: The display system includes a display system including an image-capturing apparatus including an image-capturing element; an image processing apparatus that performs image processing on the image; and a display apparatus including a display device that displays the image resulting from the image processing. The image processing apparatus includes an image processor that performs the image processing on a predetermined number of line images corresponding to a part of a frame image captured by the image-capturing element, sequentially outputs the image to the display apparatus per the predetermined number of line images, and causes the display apparatus to display the frame image; and a storage device that stores the predetermined number of line images until the frame image is completed. The image processor is configured to perform the image processing including frame unit processing on the predetermined number of line images associated with the frame image to be output.Type: GrantFiled: July 19, 2018Date of Patent: June 4, 2019Assignee: Japan Display Inc.Inventors: Yutaka Ozawa, Akira Sakaigawa, Keiji Fukuhara
