Abstract
The present invention relates to a method for detecting and showing quality of a preview or stored picture in an electronic imaging device, which comprises the steps of determining whether the electronic imaging device is operated in a preview mode or a file mode; detecting at least four features of the preview or stored picture; determining whether each of the features of the preview or stored picture is normal or not; and displaying the preview or stored picture and at least one of four graphical indicators on a LCD screen of the electronic imaging device when it is determined that the feature corresponding to the graphical indicator is not in a normal status. Thus, a user is able to easily identify the features of the preview or stored picture in a graphical way on the LCD screen in a real time while reviewing the preview or stored picture.
