Abstract: An image encoding apparatus, which is configured to perform image encoding based on a gradual decoder refresh scheme, includes a pre-processor configured to receive a video signal obtained by slicing one screen into a plurality of sub-screens and perform pre-processing, and an image encoder configured to receive output of the pre-processor, perform an encoding process, and generate stream data. The image encoder is configured to acquire information of a first Intra-slice corresponding to a target Intra-slice in a first sequence with respect to the target Intra-slice in a second sequence, in which encoding is performed, after the first sequence; and is configured to estimate an Intra-slice line number and an Inter-slice line number of the second sequence not to exceed a target information amount based on the acquired information of the first Intra-slice.
