PROBLEM TO BE SOLVED: To detect a fixed pattern noise quickly with a small memory resource.SOLUTION: The processing unit of an image analyzer corrects image data acquired from an image sensor based on the learning results in the past of a noise generation pixel generating a fixed pattern noise, and then converts it into binary image data (S310), and further performs labelling of the binary image data (S320). Based on the results of labelling, an isolated high luminance pixel is extracted from the binary image data (S330). Furthermore, one of the isolated high luminance pixels thus extracted is selected as a pixel to be determined (S350), and the luminance in image data to be corrected of a peripheral pixel corresponding to the pixel to be determined is referred (S360). When all peripheral pixels have a luminance less than a threshold (YES at S370), a pixel to be determined is detected as a new noise generation pixel (S380). |
