An image processing apparatus rendering a plurality of objects includes a CPU cache used for rendering, a determination unit configured to determine whether a cache miss of the CPU cache occurs in rendering of the plurality of objects, and a rendering unit configured to, in a case where the determination unit determines that the cache miss occurs, execute division rendering processing for generating a bitmap corresponding to the plurality of objects by classifying the plurality of objects into a plurality of groups and for rendering the plurality of objects by each group so that the cache miss does not occur, and, in a case where the determination unit does not determine that the cache miss occurs, generate a bitmap corresponding to the plurality of objects by executing rendering without classifying the plurality of objects into the plurality of groups.
