Image processing device setting sharpness adjustment degrees for object regions and performing unsharp masking process

摘要

An image processing device includes a processor. The processor is configured to perform: acquiring input image data representing an input image having a plurality of objects; identifying a plurality of object regions in the input image, the plurality of object regions representing respectively the plurality of objects; generating a mask image using sharpness adjustment degrees that are set for the plurality of object regions respectively; generating output image data by performing an unsharp masking process on the input image by using the mask image, the unsharp masking process being performed so as to adjust sharpness of the input image; and sending the output image data to a printing unit.

1. An image processing device comprising:
a processor configured to perform: acquiring input image data representing an input image having a plurality of objects, the plurality of objects including a first object and a second object different from the first object; identifying a plurality of object regions in the input image, the plurality of object regions representing respectively the plurality of objects, the plurality of object regions including a first object region and a second object region, the first object region representing the first object, the second object region representing the second object; generating a mask image using sharpness adjustment degrees that are set for the plurality of object regions respectively, the sharpness adjustment degrees including a first degree and a second degree different from the first degree, the first degree being set for the first object region, the second degree being set for the second object region; generating output image data by performing an unsharp masking process on the input image by using the mask image, the unsharp masking process being performed so as to adjust sharpness of the input image; and sending the output image data to a printing unit.
