The self-image diagnosis system includes an image processing device (110) that generates a display image and a display device (120) that displays an image generated by the image processing device (110). The image processing device (110) is returned from the display device, the reference signal drawing unit (111) for generating the image of the reference signal, the video encoding output unit (112) for encoding and outputting the image of the reference signal. And an input / output comparison unit (113) for comparing the image and the image generated by the reference signal drawing unit. The display device (120) includes a video decoding input unit (121) that decodes an input video signal, a video display unit (123) that performs image quality correction of the decoded image and displays the decoded image on a display panel (122), An image cutout unit (124) that cuts out an image at a position corresponding to the reference signal from an image before image quality correction and transmits the cut image to the image processing apparatus;
