摘要：
The spatial frequency response (SFR) for a digital still camera is affected by non-linear image processing. We analyze the influence of image enhancement processing and gamma correction on SFR characteristics by varying the edge chart contrast. SFR expressions depending on the chart image contrast are proposed, as is a measurement method of resolving power based on the slanted edge.
