Abstract

The present invention discloses an information processing apparatus, a method for controlling the information processing apparatus, and a program. Provided is an information processing apparatus including a first processing unit capable of processing an image; a second processing unit capable of processing an image in parallel for each unit of divided images; and a controller section configured to control to select the first processing unit, the second processing unit, or both the first processing unit and the second processing unit as one or more subjects for processing the image, where both the first processing unit and the second processing unit are selected In this case, the image is divided into a first area and a second area, and the processing of the image of the first area obtained by the division and the processing of the image of the second area obtained by the division are assigned to the first processing unit and the second area, respectively. processing unit to execute.

Description

technical field [0001] The present invention relates to an information processing device configured to process images, a method for controlling the information processing device, and a program. Background technique [0002] In recent years, the enhanced performance and high functionality of general-purpose computer hardware have enabled image processing that was previously only possible with dedicated hardware to be realized using general-purpose computer hardware. In computer hardware, specifically, a CPU and a memory used as a main memory exhibit extremely high speed, and therefore, various complicated special effect processing for large-capacity image data can be performed in an economically satisfactory period of time . [0003] Image processing can be performed at a higher speed by introducing a GPU (Graphics Processing Unit), which is an arithmetic processing device designed exclusively for parallel arithmetic processing. Parallel arithmetic processing by GPUs exhibi...
