Abstract
To make it possible to accurately grasp an exposure state even in the case where noise is included in captured image data. An input image data acquisition unit configured to acquire input image data including a chart, a noise reduction unit configured to perform noise reduction on the input image data, and a histogram generation unit configured to generate a histogram of luminance of the input image data based on noise reduced image data are included, and the noise reduction unit performs noise reduction on the chart area of the input image data in a degree greater than that in which noise reduction is performed on an area other than the chart.
