Patent number: 11995850Abstract: An image processing device comprises a data group generator, a gradient value manager, and a cost volume manager. The data group generator is configured to receive pixel values of an image that include phase and brightness information, and determine data groups indicating disparity of the image based on target pixel values, where the data groups correspond to a range that is determined according to the phase information. The gradient value manager is configured to determine gradient values of a region corresponding to the target pixel values and determine gradient information. The gradient information is determined by applying threshold values to the gradient values, where the threshold values are determined according to the target pixel values. The cost volume manager is configured to determine a cost volume by weighted summing the data groups based on the gradient information.Type: GrantFiled: September 15, 2022Date of Patent: May 28, 2024Assignee: SK hynix Inc.Inventors: Ji Hee Han, Jong Heon Kim, Ju Hyun Cho
