System and image processing device with evaluation value indication

A system, comprising:

• an image processing device connected to a transmission and reception device that communicates with an external device;
• and
• a terminal device connected to a display device, wherein
• the image processing device includes
• an evaluation value calculation processor that calculates, for each of two or more types of output modes, an evaluation value of output image data when image data is output in the output mode, and
• an evaluation information transmitter that transmits evaluation information including information based on the evaluation value for each of the output modes, to the terminal device, via the transmission and reception device, and
• the terminal device includes
• a display controller that performs control of displaying, for each of the output modes, the information based on the evaluation value corresponding to the output mode, on the display device, if the evaluation information is received,
• wherein
• the image processing device further includes an identifier that identifies, for each of the output modes, a block having a large degree of information loss among blocks composed of one or a plurality of pixels of the image data,
• the evaluation information includes information indicating a block having a large degree of information loss, and
• the display controller displays, for each of the output modes, a block having a large degree of information loss.
