Abstract
According to an embodiment of this invention, an image processing apparatus generates image data to be used to print an image on a print medium, based on a print job transmitted from a host, generates first print data by performing image processing on part of the generated image data, stores the first print data in a first memory, generates second print data by performing image processing on a remaining part of the generated image data, and stores the second print data in a second memory. The apparatus further transfers the first print data from the first memory to the second memory, composes the first print data and the second print data stored in the second memory, and transfers the composite data as print data to a continuous area of a third memory.
Claims19
An image processing apparatus comprising:
- a generation unit configured to generate image data to be used to print an image on a print medium based on a print job transmitted from a host;
- a first image processing unit configured to generate first print data by performing image processing on part of the image data generated by the generation unit, and store the first print data in a first memory;
- a second image processing unit configured to generate second print data by performing image processing on a remaining part of the image data, and store the second print data in a second memory;
- a composition unit configured to compose the first print data and the second print data to generate print data to be output to an outside, and store the generated print data in a third memory;
- a first transfer unit configured to transfer the first print data from the first memory to the second memory;
- and
- a second transfer unit configured to transfer the first print data and the second print data stored in the second memory to a continuous area of the third memory.
An image processing method comprising:
