Abstract
An image processing apparatus capable of performing pixel synthesis processing at high speed. Synthesis processing of a first object and a second object is performed for an area where the first object and the second object overlap each other. A first image formation processor stores first pixel data, which corresponds to the area, of pixel data of the first object, in a first communication memory and stores second pixel data, which corresponds to the area, of pixel data of the second object, in a second communication memory. A second image formation processor acquires the first and second pixel data from the first and second communication memories, respectively, and performs synthesis processing of the acquired first and second pixel data.
Claims11
An image processing apparatus that performs synthesis processing for an area where a first object and a second object overlap each other, comprising:
- a first processing unit configured to generate first pixel data, which corresponds to the area in the first object and generate second pixel data, which corresponds to the area in the second object;
- two different communication paths;
- and
- a second processing unit configured to receive the first and second pixel data via the two different communication paths from the first processing unit and perform the synthesis processing of the received first and second pixel data;
- wherein the first pixel data is transmitted from the first processing unit to the second processing unit through one of the two different communication paths, and the second pixel data is transmitted from the first processing unit to the second processing unit through the other of the two different communication paths,
- wherein the transmission of the first pixel data is performed in parallel with the transmission of the second pixel data, and
- wherein the second processing unit is configured to start the synthesis processing of the first and second pixel data before completion of receiving the first and second pixel data.
An image processing method for an image processing apparatus that includes two different communication paths, and performs synthesis processing for an area where a first object and a second object overlap each other, comprising:
- generating first pixel data, which corresponds to the area in the first object, and generating second pixel data, which corresponds to the area in the second object;
- and
- receiving the first and second pixel data via the two different communication paths, and performing the synthesis processing of the received first and second pixel data;
- wherein the first pixel data is transmitted through one of the two different communication paths, and the second pixel data is transmitted through the other of the two different communication paths,
- wherein the transmission of the first pixel data is performed in parallel with the transmission of the second pixel data, and
- wherein the synthesis processing of the first and second pixel data is started before completion of receiving the first and second pixel data.
