Camera, camera system, and self-diagnosis method

A camera system comprising:

• a camera and a server device that communicates with the camera, wherein
• the camera includes:
• a capture unit that generates an image by capturing an area in which an evaluation-use object is present;
• a calculation unit that analyzes the image, and thereby detects the evaluation-use object in the image and calculates meaningful information from the evaluation-use object in the image;
• an object information acquisition unit that acquires and stores object information that is meaningful to a user and derived from the evaluation-use object;
• an evaluation unit that performs an evaluation that includes comparing the meaningful information and the object information, and thereby calculating a degree of matching between the meaningful information and the object information, the evaluation determining whether or not a desired result is obtained from the image;
• and
• an output unit that outputs a result of the evaluation to the server device, and
• the server device includes:
• an object information storage unit that stores the object information used by the camera;
• and
• an acquisition output unit that acquires the result of the evaluation outputted by the camera and outputs the result of the evaluation so acquired.

A self-evaluation method performed by a camera, comprising:

• generating an image by capturing an area in which an evaluation-use object is present;
• analyzing the image, and thereby detecting the evaluation-use object in the image and calculating meaningful information from the evaluation-use object in the image;
• acquiring object information that is meaningful to a user and derived from the evaluation-use object;
• and
• performing a self-evaluation that includes comparing the meaningful information and the object information, and thereby calculating a degree of matching between the meaningful information and the object information, the self-evaluation determining whether or not a desired result is obtained from the image.
