Paper Abstract
A new method for evaluating the perceptual resolution of the actual image has been developed. The characteristic of this
new evaluation method is that the square sum of the cross correlation coefficients becomes the index of the evaluation.
Because the RIT Contrast-Resolution Test Target was a very systematic analysis pattern that contains spatial resolution
and contrast, it was used for this study. The cross correlation coefficient is calculated between the reference image and
the printed image read by a scanner. To provide the precision of the new evaluation method, subjective evaluation was
performed with the actual image. As a result of having confirmed correlation of the evaluation value from subjective
evaluation and the new evaluation method, the correlation was much higher than other evaluation method using a similar
analysis pattern. Furthermore, the sharpness evaluation of the actual image was enabled by applying the evaluation value
of this new method to evaluate the perceptual resolution, that correlation with the subjectivity was high.
