Abstract
A predetermined quantity of parameter values, that are varied in stages, are generated on the basis of the value of a reference parameter input by a user. A print job is generated that includes a drawing command for printing a reduced image of image data, and this drawing command is converted into raster data and stored. A predetermined quantity of the stored raster data is copied, and the stored raster data is subjected to image adjustment processing on the basis of the reference parameter. The copied raster data is also subjected to image adjustment processing on the basis of the generated parameter values.
Claims7
An information processing apparatus, comprising:
- an acquisition unit configured to acquire image data;
- an accept unit configured to accept a reference parameter that sets a reference image quality;
- a parameter generation unit configured to generate a predetermined quantity of parameter values that are varied in stages, on the basis of the reference parameter;
- a job generation unit configured to generate a print job including a drawing command for printing a reduced image of the image data;
- a conversion unit configured to convert the drawing command included in the print job into raster data;
- a storage unit configured to store the raster data converted by the conversion unit;
- a copying unit configured to copy a predetermined quantity of the raster data stored by the storage unit;
- a first processing unit configured to subject the raster data copied by the copying unit to image adjustment processing on the basis of the reference parameter;
- and
- a second processing unit configured to subject the raster data copied by the copying unit to the image adjustment processing on the basis of the parameter values generated by the parameter generation unit.
An information processing method executed by an information processing apparatus, comprising:
- an acquisition step of acquiring image data;
- an accept step of accepting a reference parameter that sets a reference image quality;
- a parameter generation step of generating a predetermined quantity of parameter values that are varied in stages, on the basis of the reference parameter;
- a job generation step of generating a print job including a drawing command for printing a reduced image of the image data;
- a conversion step of converting the drawing command included in the print job into raster data;
- a storage step of storing the raster data converted by the conversion step;
- a copying step of copying a predetermined quantity of the raster data stored by the storage step;
- a first processing step of subjecting the raster data copied by the copying step to image adjustment processing on the basis of the reference parameter;
- and
- a second processing step of subjecting the raster data copied by the copying step to the image adjustment processing on the basis of the parameter values generated by the parameter generation step.
A recording medium that can be read by a computer and that stores a program that causes the computer to execute the steps of:
- an acquisition step of acquiring image data;
- an accept step of accepting a reference parameter that sets a reference image quality;
- a parameter generation step of generating a predetermined quantity of parameter values that are varied in stages, on the basis of the reference parameter;
- a job generation step of generating a print job including a drawing command for printing a reduced image of the image data;
- a conversion step of converting the drawing command included in the print job into raster data;
- a storage step of storing the raster data converted by the conversion step;
- a copying step of copying a predetermined quantity of the raster data stored by the storage step;
- a first processing step of subjecting the raster data copied by the copying step to image adjustment processing on the basis of the reference parameter;
- and
- a second processing step of subjecting the raster data copied by the copying step to the image adjustment processing on the basis of the parameter values generated by the parameter generation step.
