IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

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.

1. An image processing apparatus comprising:
an input image data acquisition unit configured to acquire input image data that is obtained by capturing an image including a chart as part of a subject; 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 color of the input image data based on noise reduced image data, wherein the histogram is generated based on image data in which noise reduction has been performed on the chart area of the input image data in a degree greater than that in which noise reduction has been performed on an area other than the chart.
