Image encoding apparatus, image encoding method, and image encoding program stored in storage medium

An image encoding method causing a computer to execute a process, the process comprising:

• calculating, from an encoding throughput for image data to be encoded that is obtained based on a parameter regarding an encoding throughput, and a maximum throughput of an image encoding apparatus, an available throughput that occurs in a process of encoding the image data to be encoded;
• allocating, in accordance with the calculated available throughput, a function of enhancing precision of encoding to the image data to be encoded;
• and
• encoding, by using the allocated function, the image data to be encoded.

A non-transitory computer-readable storage medium storing an image encoding program for causing a computer to execute a process, the process comprising:

• calculating, from an encoding throughput for image data to be encoded that is obtained based on a parameter regarding an encoding throughput, and a maximum throughput of an image encoding apparatus, an available throughput that occurs in a process of encoding the image data to be encoded;
• allocating, in accordance with the calculated available throughput, a function of enhancing precision of encoding to the image data to be encoded;
