摘要

The technique of the present disclosure provides an image processing apparatus for estimating a printing result of image data to be printed with a small amount of operation after the image data is obtained. The apparatus is an image processing apparatus for estimating a printing result to be obtained by printing input image data with a printer, including: an obtaining unit that obtains the input image data; and an estimation unit that estimates the printing result based on the input image data. The estimation unit has been caused to learn scanned image data as correct data, the scanned image data being obtained by reading, with a scanner, a printing result obtained by printing predetermined image data with the printer.

說(shuō)明書(shū)

In the present embodiment, the tone of the input image data is 1 bit, the tone of the intermediate data is 1 bit, and the tone of the estimated image data is 8 bits. Note, however, that the technique of the present disclosure is not limited to these. In an example, the tone of the input image data may be 2 bits, the tone of the intermediate data may be 2 bits, and the tone of the estimated image data may be 16 bits.

The learning unit 205 includes a first learning unit 206, a second learning unit 207, and a learning intermediate data obtaining unit 208. The first learning unit 206 causes the first estimation unit 203 to learn the weights of layers in a neural network, which are its internal parameters. Likewise, the second learning unit 207 causes the second estimation unit 204 to learn the weights of layers in a neural network, which are its internal parameters.
