WIPO Patent Application WO/2020/216057

A1

As the distance to a determined subject changes, it sometimes results in the inability to stably perform photographing control. The control device can include a circuit configured to apply a first contrast evaluation filter for an area comprising the subject in a first image, i.e., a first area, so as to export a first contrast evaluation value that is used for evaluating a contrast value of the first area; perform focusing control on a photographing device according to the first contrast evaluation value; determine a second contrast evaluation filter according to a first distance between the photographing device and the subject when the first image is photographed by the photographing device, and a second distance between the photographing device and the subject when a second image is photographed by the photographing device; apply a contrast evaluation filter for an area comprising the subject in the second image, i.e., a second area, so as to export a second contrast evaluation value that is used for evaluating a contrast value of the second area; and perform focusing control on the photographing device according to the second contrast evaluation value.
