Abstract: A method for blurred image judgment is provided. Firstly, a focus value FV1 of an original image is calculated. By using a blur function, the original image is obfuscated to generate a blurred image, and then the focus value FV2 of the blurred image is calculated. A blur ratio FV1/FV2 is compared with a blur threshold value Tp, thereby discriminating whether the original image is blurred according to the comparing result. The method for blurred image judgment is applicable to a digital image capture device. If the original image is deemed blurred, a blur image signal is issued to notify the user whether the retaking operation is done.

Abstract: An abnormal sound detection device for detecting a peripheral interface device includes a vibration simulation mechanism, a movable-type audio collecting device and a controlling and analyzing device. The vibration simulation mechanism includes a mechanism body. The peripheral interface device is accommodated within the mechanism body. The vibration simulation mechanism generates a vibration force. The peripheral interface device generates a vibration sound wave in response to the vibration force. The movable-type audio collecting device collects the vibration sound wave. The audio collecting device generates a vibration audio signal in response to the vibration sound wave. The controlling and analyzing device generates an abnormal sound detection signal to control the vibration simulation mechanism to generate the vibration force. The controlling and analyzing device detects and identifies whether there is an abnormal sound phenomenon in the vibration audio signal.

Abstract: A control device with a capacitive-type visual key structure is provided. The control device includes a covering member and a transparent keycap. The covering member includes an accommodation space. The transparent keycap is accommodated within the accommodation space. An elastic element, a first electrode, a key circuit board assembly with a second electrode and a display panel are accommodated within the accommodation space. When the transparent keycap is pressed down, the elastic element is correspondingly moved, and a spatial distance between the first electrode and the second electrode is changed. Consequently, a capacitance change value is formed. According to the capacitance change value, the control device judges whether the transparent keycap is pressed down and triggered.
