Image processing apparatus and non-transitory computer readable medium storing program

An image processing apparatus comprising:

• an input unit that inputs an image;
• and
• a hardware processor configured to read out a program stored in a memory, and executes the program,
• wherein the hardware processor is configured to
• detect an intended subject from the input image by a first detection method, set an intended subject region for the detected intended subject,
• detect the intended subject from the input image by a second detection method different from the first detection method, and
• update the set intended subject region by using a detection result of the second detection method,
• wherein the hardware processor is configured to detect a salient region from the input image, as the second detection method, and update the set intended subject region by expanding the set intended subject region by using the salient region,
• wherein the hardware processor is configured to limit an expansion range of the intended subject region by the detection result, and decide an upper limit of the expansion, and
• wherein the hardware processor is configured to expand the intended subject region by adding pixels which are adjacent to the intended subject region and are detected in the detection result to pixels of the intended subject region.
