Camera device and image processing method

An image processing method executed by a camera device communicably connected to an external device, the image processing method comprising:

• capturing an image of an imaging area in which a subject is present;
• detecting the subject from the captured image;
• primarily determining a color of a target portion of the detected subject;
• adjusting a determination result of a predetermined color corresponding to the determined target portion based on a camera parameter related to imaging when the determined color of the target portion is the predetermined color having a plurality of gradations;
• and
• transmitting an adjustment result of the predetermined color corresponding to the determined target portion and information on the target portion to the external device in association with each other.

A system, comprising:

• a processor;
• and
• a memory that stores a camera parameter related to a captured image and that includes at least one program which, when executed by the processor, causes the processor to perform operations, the operations including:
• generating the captured image of an imaging area in which a subject is present;
• detecting the subject from the captured image;
• determining a color of a target portion of the subject;
• adjusting a determination result of a predetermined color corresponding to the target portion of the subject, based on the camera parameter related to the captured image, when the color of the target portion is the predetermined color having a plurality of gradations;
• and
• transmitting an adjustment result of the predetermined color corresponding to the target portion in association with information on the target portion to an external device.
