1. An apparatus to restore an encoded image, the apparatus comprising;
- a decoder configured to perform a restoring process on the encoded image, the decoder including;
a memory configured to store a plurality of processor instructions;
a processor configured to execute an intra-mode restoring function on the encoded image using the plurality of processor instructions; and
a hard-wired circuit configured to execute an inter-mode restoring function on the encoded image, andwherein the decoder configured to perform operations comprising,determining a memory access frequency of the restoring process or a number of operations of the restoring process,identifying the restoring process from among the intra-mode restoring function and the inter-mode restoring function based on the memory access frequency of the restoring process or the number of operations of the restoring process,switching to the intra-mode restoring function in response to the determining indicating that the memory access frequency is below a first threshold or the number of operations exceeds a second threshold, or to the inter-mode restoring function otherwise, andperforming the intra-mode restoring function or the inter-mode restoring function selected by the switching, the intra-mode restoring function being performed by executing the plurality of processor instructions, the inter-mode restoring function being performed using a hard-wired circuit.

Abstract
Restoring an image is achieved by restoring a block by executing at least one first restoring function and at least one second restoring function. The first restoring function may be implemented using software, and the second restoring function may be implemented using hardware. By assigning restoring functions to be either first restoring functions or second restoring functions, even an image having high resolution can be restored and reproduced in real-time.
