Patent ID: 8019159

Claim:
A method for informing a user of an image recognition error in an imaging system, the method comprising the steps of: (1) generating image data by taking a picture of an object of recognition if image recognition is requested by a user; (2) calculating analysis indices corresponding to environmental factors by detecting from the image data the environmental factors that may cause the image recognition errors; (3) determining whether the analysis indices are suitable for image recognition by checking whether each of the analysis indices is included in or excluded from a normal range of reference values; and (4) informing the user of the cause of the image recognition error after perceiving that each of the environmental factors corresponding to the analysis indices excluded from the normal range of the reference values is a cause of the image recognition error if any of the analysis indices are excluded from the normal range of the reference values, wherein the environmental factors include at least one among an illumination state and a size state of the image data, and an angle state of the object of recognition.
