Abstract
A display list generation apparatus includes an interpretation unit configured to interpret page description language (PDL) data and store an interpretation result of the PDL data in a first storage unit, a copying unit configured to copy the interpretation result stored in the first storage unit, in a second storage unit, and a generation unit configured to generate a display list from the interpretation result stored in the first storage unit in a case where a data size of the interpretation result exceeds a predetermined threshold and generate a display list from the copy of the interpretation result stored in the second storage unit in a case where the data size of the interpretation result does not exceed the predetermined threshold.
