Abstract: Methods of processing a frame in a video sequence of digital images are provided. The methods include determining a global motion vector for the frame relative to a previous frame in the sequence, deriving a jitter function from the global motion vector, the jitter function including an estimate of undesired motion of the frame relative to the previous frame, and determining whether the frame is blurred above a first predetermined threshold. If the frame is blurred above the first predetermined threshold, stabilizing the frame using the jitter function and applying a deblur function to the frame.

Abstract: Control panel including a cover mounted on a support that is provided with a tactile pressing detection zone in which a force sensor that includes a pressure-sensitive zone is arranged behind a detection zone between the cover and the support so as to produce an electrical control signal when a user applies a determined tactile pressing force to the detection zone. The tactile pressing force is transmitted axially (X1) towards the sensitive zone via a spacer made of elastically compressible material interposed between the sensor and the cover. The spacer includes at least one compressible portion that defines a transversal top surface that bears against the cover and a transversal bottom surface that bears against the sensitive zone of the sensor. The top surface has an area smaller than the area of the bottom surface.

Abstract: Pressure sensitive transducer assembly that includes a force sensing resistor. The force sensing resistor includes: first and second substrates; at least a first and a second electrically conductive traces on the inner surface of the first substrate including interdigitated fingers defining a sensitive area; and a resistive layer facing the sensitive area. The force sensing resistor includes an auxiliary trace on the inner surface of the first substrate connecting the first trace to the second trace through a constant resistance that is not dependent on the force applied to the substrates. The constant resistance being of a value largely greater than the value of the variable resistance which can be measured indirectly between the fingers when an external force is applied to the substrates. A system and a control method are also proposed.

Abstract: The invention concerns a method for digital image stabilization for removing jitter from an original sequence of images (10) generated by a camera. The original sequence (10) is applied to a stabilization algorithm (11). The global motion of a camera is estimated and filtered (110) using a default motion filter. Predetermined parameters (13, 140, 141) are extracted from both the original (10) and stabilized (12) sequences of images. A measure value is computed in order to evaluate (15) the stabilization quality and compared to a threshold. Depending on the results of the evaluation (O15, O?15) the stabilization algorithm (11) uses an alternative filter, in order to improve stabilization quality, or continues to use the default filter.

Abstract: The present invention relates to a method and system for a digital image stabilization intended to remove unwanted camera movement or jitter, both translational and rotational jitter. The system comprises the following means: 1) a motion estimation stage (10) of the global motion of the camera: block motion vectors are calculated for specific parts of the image and global motion parameters representing the camera motion are then derived. 2) a motion/jitter filtering stage (11): the translation vector and the rotation angle are filtered separately, a boundary check being then performed for verifying if the correction thus done is not above an allowed threshold. 3) a jitter compensation stage (12): the raw sequence is compensated according to the extracted jitter and the result is a stabilized sequence.
