A computational display and an operating method thereof are disclosed. The computational display includes an image dividing module, a decomposition calculating module, a block combining module and a display module. The image dividing module is used to divide an initial light-field image into a plurality of target blocks. The decomposition calculating module is coupled to the image dividing module and used to independently apply a decomposition algorithm to each of the plurality of target blocks. The block combining module is coupled to the decomposition calculating module and used to combine the plurality of target blocks into a result light-field image. The display module including multi-layer display units is coupled to the block combining module and used to display result light-field image. |
