Claim One:
1. An image processing device comprising: a processor configured to: acquire original image data representing an original image; acquire a level selected from a plurality of levels that represent compression degrees; and compress the original image data according to the original image data and the selected level so as to generate compressed image data, wherein, to compress the original image data, the processor is configured to: compress first original image data using a first-type compression method when the original image data is the first original image data representing an original image including a character having a first size and when the selected level is a specific level of the plurality of levels; and compress second original image data using a second-type compression method that is different from the first-type compression method when the original image data is the second original image data representing an original image including a character having a second size that is smaller than the first size and when the selected level is the specific level; wherein the processor is further configured to: specify a plurality of compression methods corresponding to the plurality of levels, wherein when the original image data is the first original image data, the first-type compression method is assigned to a1 number of levels of the plurality of levels and the second-type compression method is assigned to a2 number of level(s) of the plurality of levels, wherein when the original image data is the second original image data, the first-type compression method is assigned to b1 number of level(s) of the plurality of levels and the second-type compression method is assigned to b2 number of levels of the plurality of levels, and wherein a1, a2, b1, and b2 satisfy b1<a1, b2>a2, and a1+a2=b1+b2; and wherein the processor is further configured to: analyze the original image data so as to determine a size of a character in the original image; and specify the plurality of compression methods corresponding to the plurality of levels, based on the size of the character.
