Abstract: A hologram generating apparatus is provided. The apparatus includes a hologram signal generating unit configured to, based on light projected on at least some points corresponding to an object, generate a hologram signal corresponding to the at least some points on at least one two-dimensional plane, a processor configured to calculate a sparsity corresponding to the two-dimensional plane based on the hologram signal, and to calculate a fringe pattern based on at least some of the hologram signal, and a pattern writing unit configured to record the fringe pattern on a computer-generated holography (CGH) plane, wherein the processor is further configured to repeatedly calculate a fringe pattern until a number of dominant signals of the calculated fringe pattern coincides with a predetermined threshold value determined based on the sparsity.

Abstract: A content providing apparatus is disclosed. The content providing apparatus comprises: a communication unit for communicating with an external apparatus; an image processing unit for generating a compressed image by image-processing an input original image; and a control unit for controlling the communication unit to divide the original image into one or more regions based on the image quality, to obtain characteristic information for each region from the respective regions, and to transmit the obtained characteristic information for each region together with the compressed image to the external apparatus. As the result, the display apparatus may perform image quality improvement operation so that the image quality is close to the original quality level by extracting information required for improving the image quality and transmitting the same together with a compressed image in production and encoding steps before transmitting the image.
