Increased customer interest in image quality has caused market frenzy in the camera world. Recent digital camera development tendency provides a much higher image quality to meet customers’ demand of image quality satisfaction. However, it is hard to confirm that development of objective image quality performance means positive image quality preference. Further, there is no evidence of any previous research that examined the correlation between objective and subjective image quality comparison. Therefore, it is necessary to analyze the customers’ preferred images based on objective image quality performance. Throughout this study, we analyze the statistical correlation between the objective and subjective image quality assessment by using International Organization for Standardization (ISO) standards. Based on the study results, we recommend not only evaluating customers’ preferences, but also analyzing the preferred image quality to validate and confirm the correlation between objective and subjective image quality. Moreover, we expect these results to positively influence product development.
