Image processing apparatus and non-transitory computer readable medium with background emphasis of reduced image
An image processing apparatus includes a first generation unit and a second generation unit. The first generation unit generates reduced original image data for forming a reduced image of an original image to be formed on the basis of print data. The second generation unit generates background-emphasized reduced image data for forming a reduced image in which a reduced background region is emphasized in the reduced image, and the reduced background region corresponds to a background region of an object included in the original image.
1. An image processing apparatus comprising:
a processor configured to:
generate reduced original image data for forming a reduced image of an original image to be formed on the basis of print data;
generate background-emphasized reduced image data for forming a reduced image in which a reduced background region is emphasized to enhance visibility of the reduced image, the reduced background region corresponding to a background region of an object included in the original image; and
output the reduced original image data or the background-emphasized reduced image data, and the background-emphasized reduced image data is output if a ratio of the reduced background region to all regions in the reduced image exceeds a threshold.
2. The image processing apparatus according to claim 1 , wherein image data of the reduced background region in the background-emphasized reduced image data is generated on the basis of the background region or the reduced background region.
3. The image processing apparatus according to claim 2 , wherein the image data of the reduced background region in the background-emphasized reduced image data is image data of a complementary color of the background region or the reduced background region.
4. The image processing apparatus according to claim 3 , wherein in the image data of the complementary color, a degree of the complementary color is changeable in accordance with color components of the background region or the reduced background region.
5. The image processing apparatus according to claim 1 , wherein image data of the reduced background region in the background-emphasized reduced image data is image data of a complementary color of the background region or the reduced background region.
6. The image processing apparatus according to claim 5 , wherein in the image data of the complementary color, a degree of the complementary color is changeable in accordance with color components of the background region or the reduced background region.
7. The image processing apparatus according to claim 1 ,
wherein the processor is configured to cause the reduced original image data to be stored in a single storage area, and
wherein the processor is configured to emphasize image data of the reduced background region in the reduced original image data stored in the single storage area to generate the background-emphasized reduced image data.
8. The image processing apparatus according to claim 7 , wherein, if the reduced original image data is used after the background-emphasized reduced image data has been generated, the processor is configured to restore the reduced original image data from the background-emphasized reduced image data stored in the single storage area.
9. A non-transitory computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:
generating reduced original image data for forming a reduced image of an original image to be formed on the basis of print data;
generating background-emphasized reduced image data for forming a reduced image in which a reduced background region is emphasized to enhance visibility of the reduced image, the reduced background region corresponding to a background region of an object included in the original image; and
outputting the reduced original image data or the background-emphasized reduced image data, and the background-emphasized reduced image data is output if a ratio of the reduced background region to all regions in the reduced image exceeds a threshold.
10. An image processing apparatus comprising:
a processor configured to:
generate reduced original image data for forming a reduced image of an original image to be formed on the basis of print data;
generate background-emphasized reduced image data for forming a reduced image in which a reduced background region is emphasized to enhance visibility of the reduced image, the reduced background region corresponding to a background region of an object included in the original image;
cause the reduced original image data to be stored in a single storage area; and
emphasize image data of the reduced background region in the reduced original image data stored in the single storage area to generate the background-emphasized reduced image data.
