Target-image detecting device, control method and control program thereof, recording medium, and digital camera

A control program stored on a non-transitory computer-readable medium for controlling a target-image detecting device configured to detect a target image as a part of photographed images and as an image of a target object from the photographed images, that causes a computer to perform:

• sequentially obtaining a plurality of the photographed images that form a moving image;
• detecting a target image included in the obtained photographed images, generating a detection result and accumulating the generated detection result in memory as detection history;
• referring to the detection history of the memory and deciding whether the detection result of the target image of the same target object is included in a latest predetermined number of detection results;
• outputting the detection result when the detection result is included;
• and
• not outputting the detection result when the detection result is not included, wherein the detecting the target image includes accumulating identification information for identifying the detected target image in the memory by relating the identification information to the detection result,
• wherein, when a target image of which a target object detected this time is the same as that of the target image detected in the past, the detecting the target image includes accumulating, in the memory, identification information that is the same as identification information of the target image detected in the past by relating the identification information to a detection result of the target image detected this time, and
• wherein deciding whether the detection result of the target image of the same target object is included in the latest predetermined number of detection results includes making the decision by using the identification information of the target image.

A method for controlling a target-image detecting device configured to detect a target image as a part of photographed images and as an image of a target object from the photographed images, the method comprising:

• sequentially obtaining via a computer a plurality of the photographed images that form a moving image;
• detecting a target image included in the obtained photographed images, generating a detection result and accumulating the generated detection result in memory as detection history;
• referring to the detection history of the memory and deciding whether the detection result of the target image of the same target object is included in a latest predetermined number of detection results;
• outputting the detection result when the detection result is included and displaying on a display a synthesized image synthesized based on the detection result;
• and
• not outputting the detection result when the detection result is not included, wherein the detecting the target image includes accumulating identification information for identifying the detected target image in the memory by relating the identification information to the detection result, wherein, when a target image of which a target object detected this time is the same as that of the target image detected in the past, the detecting the target image includes accumulating, in the memory, identification information that is the same as identification information of the target image detected in the past by relating the identification information to a detection result of the target image detected this time, and
• wherein deciding whether the detection result of the target image of the same target object is included in the latest predetermined number of detection results includes making the decision by using the identification information of the target image.
