a first generation unit that certifies, for each of the plurality of blocks, whether the original image is a barcode area, and that generates area information indicating whether the original image is the barcode area, the area information being associated with each of the blocks; a storage unit that stores output image data for outputting the original image; and an output unit that performs output based on the output image data using methods that are different between an area indicated, by the area information, to be the barcode area and an area indicated not to be the barcode area, wherein the output image data is JPEG data compressed for the each block. ### Claim 2 (depends on 1) The image output device according to claim 1, further comprising: a division unit that divides the original image data into the blocks; and a second generation unit that generates, as the output image data, JPEG data obtained by compressing the original image data for the each block. ### Claim 3 (depends on 1) The image output device according to claim 1, wherein the original image data is JPEG data. ### Claim 4 (depends on 1) The image output device according to claim 1, wherein the output unit is configured such that printing is performed using a larger dot when printing an area indicated to be the barcode area than when printing an area indicated not to be the barcode area. ### Claim 5 (depends on 1) The image output device according to claim 1, wherein the output unit is configured such that printing is performed with a lower concentration with respect to the original image with an identical concentration when printing an area indicated to be the barcode area than when printing an area indicated not to be the barcode area. ### Claim 6 (depends on 1) The image output device according to claim 1, wherein the area information is 1-bit information per the one block. ### Claim 7 (depends on 1) The image output device according to claim 1, wherein the area information is information continuous to data indicating contents of the block in the output image data. ### Claim 8 An image output method comprising: acquiring original image data representing an original image, wherein the original image data has been divided into a plurality of blocks; certifying, for each of the plurality of blocks, whether the original image is a barcode area; generating area information indicating whether the original image is the barcode area, the area information being associated with each of the blocks; and performing output based on output image data for outputting the original image using methods that are different between an area indicated, by the area information, to be the barcode area and an area indicated not to be the barcode area, wherein the output image data is JPEG data compressed for the each block.
