1. An information processing device comprising:
an estimation unit configured to estimate, based on an image, influence on a subjective image quality of a decoded image by applying ZeroOut to quantization coefficients corresponding to the image at a time of a coding process of the image; and
a control unit configured to control division of a block based on the influence estimated by the estimation unit at a time of a setting process of a size of the block that serves as a unit of processing in the coding process of the image.
