Claims (11)

Input means for inputting image data;
Dividing means for dividing the image data input by the input means into small areas,
Determining means for determining whether a predetermined image is included for each of the small areas; and control means for controlling output of the image data when the determining means determines that the predetermined image is included,
An image input / output processing device comprising: The image processing apparatus further includes a conversion unit configured to convert the resolution of the image data, wherein the determination unit performs a first determination using the image data whose resolution has been reduced by the conversion unit, and the first determination determines that the image data has The method according to claim 1, wherein when it is not possible to determine whether or not a predetermined image is included, the second determination is performed using image data having a higher resolution than the image data used for the first determination. 2. The image input / output processing device according to 1. The image input / output processing apparatus according to claim 2, wherein the conversion unit performs resolution conversion by thinning out pixels from the image data. 2. The image input / output processing apparatus according to claim 1, wherein the division unit divides the image data into small bands using a band divided in parallel with a raster line. The image processing apparatus further includes a compression / expansion means for performing compression / expansion processing of the image data and a storage means for storing the image data, wherein the image data and the image data divided into the small areas are subjected to the compression processing by the compression / expansion means, and the storage is performed. 2. An image input / output processing apparatus according to claim 1, wherein said image input / output processing apparatus is stored in a storage unit, read from said storage unit, and expanded by said compression / expansion unit. 2. The image input / output processing apparatus according to claim 1, wherein the control unit does not output the image data determined to include the predetermined image by the determination unit. 6. The image input / output processing apparatus according to claim 5, wherein the control unit deletes, from the storage unit, image data determined to include a predetermined image by the determination unit. The image input / output processing apparatus according to claim 1, wherein the determination unit determines whether a predetermined image is included by detecting specific electronic watermark information superimposed on the image data. 2. The image input / output processing according to claim 1, wherein the determination unit determines whether or not the image includes a predetermined image based on a similarity between a characteristic obtained from the image data and a characteristic of the predetermined image. apparatus.
