摘要： 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.

摘要： An input device includes a casing, a base member, a ball member, a control ring and a gravity wheel. The casing includes an upper cover and a lower cover. The upper cover has an opening. The ball member is installed on the base member. The ball member is partially exposed outside the opening. The control ring is arranged around the base member. The control ring is partially exposed outside the opening. The control ring is freely rotatable around the base member. The control ring includes a first inclined part, a rack structure, and a lateral wall. The lateral wall is connected with the first inclined part and the rack structure. The gravity wheel is engaged with the rack structure. Consequently, the rotation of the control ring is suppressed by the gravity wheel.

摘要： A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes a movable block, a push block and a stopper. While the movable block is pushed and moved in response to a pushing force, the push block is correspondingly moved. While the push block is moved, the stopper is pushed by the push block, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.

摘要： A touchpad module includes a base plate, a touch member and an elastic structure between the touch member and the base plate. The elastic structure includes a supporting frame and a swingable resilience piece. There are a first fixing point and a second fixing point between the swingable resilience piece and the base plate. The swingable resilience piece includes a first resilience arm and a second resilience arm. The first resilience arm is connected between the first fixing point and a first inner side of the supporting frame. The second resilience arm is connected between the second fixing point and a second inner side of the supporting frame. When an external force is exerted on a first end of the touch member, the first resilience arm is correspondingly swung toward the base plate by using the first fixed point as a fulcrum.

摘要： A lens module and a manufacturing method of the lens module are provided. The manufacturing method includes the following steps. Firstly, a circuit substrate is provided. Then, an image sensor chip is placed on a top surface of the circuit substrate. Then, plural electrical connection paths are formed between the image sensor chip and the circuit substrate. Then, plural stacking spacer structures are formed on a top surface of the image sensor chip by a stacking process. Then, plural protective sidewalls are formed to cover the electrical connection paths. Then, a glass substrate is placed over the stacking spacer structures. Then, a lens holder structure is placed on a substrate top surface of the glass substrate directly. The glass substrate is supported by the stacking spacer structures. Consequently, the glass substrate can be maintained at the position over the image sensor chip.

摘要： A key structure includes a keycap, a scissors-type connecting element, a first knocking part, a resilience element and a second knocking part. The scissors-type connecting element is coupled to a bottom surface of the keycap. The scissors-type connecting element includes an inner frame and an outer frame. The first knocking part is disposed within a space surrounded by the inner frame. The resilience element is located under the first knocking part. The second knocking part is coupled to the bottom surface of the keycap and faces the first knocking part. While the keycap is pressed down, the second knocking part knocks on the first knocking part, and the first knocking part is moved downwardly. When the keycap is not pressed down, the first knocking part is moved upwardly and returned to an original position in response to an elastic force of the resilience element.
