摘要： An image unsharpness test method for a camera device, wherein firstly, during the focusing stage of an electronic camera device, the image with the highest sharpness is selected to be a contrast image; next, the contrast image is compared with a captured image to obtain the sharpness difference is too great, the captured image is determined to unsharp; vice versa, if the difference is very small, the captured image is determined to be sharp. Thereby, the image unsharpness test method for a camera device of the present invention not only can determine whether a captured is sharp enough but also can reduce the photographic errors and promote photographic efficiency.
