Title:
IMAGE PROCESSING APPARATUS, CONTROL METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2023136246
Kind Code:
A
Abstract:
To generate a composite image indicating a preferable brightness expression when performing additive composition of a plurality of images including one or more HDR images.SOLUTION: An image processing apparatus for generating a composite image, includes: acquisition means for acquiring a plurality of images including one or more High Dynamic Range (HDR) images; determination means for determining a peak luminance value of the composite image; and generation means for generating the composite image by executing additive composition processing using the plurality of images. The generation means controls the additive composition processing so that a signal level of each pixel of the composite image falls within an output dynamic range whose maximum value is set to a signal level corresponding to the peak luminance value determined by the determination means.SELECTED DRAWING: Figure 3
