The digital camera includes a gyroscope to measure motion of the digital camera and processes the signals from the gyroscope to track the total displacement of an image sensor over a series of frames of video. If the motion is a sustained motion in a substantially uniform direction, then the digital camera recognizes the motion as a panning-type motion and activates a fast-zero recovery with alpha blending operation to retrace the displacement of active pixel locations to the center of the image sensor. Alpha blending is performed to smooth the transition from a normal image stabilization operation to the fast-zero recovery with alpha blending operation.

  • Patent number: 8363115
    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: A first equalizer generates a vibration-component signal indicating the amount of movement of an image pickup apparatus according to an output signal of a vibration detecting element for detecting the vibration of the image pickup apparatus. The second equalizer generates a drive signal used to control a driver element to correct the position of a lens or image pickup devices, based on the output signal of a position detecting element for detecting the position of the lens to be driven or the image pickup devices to be driven and the vibration-component signal. A control unit verifies the operations of the driver element, the position detecting element, the vibration detecting element and the first equalizer, based on the output signal of the position detecting element and the vibration-component signal.

  • Publication number: 20120293670
    Abstract: Methods are disclosed for digital cameras to gain tilt information of an image sensor of the camera in order to achieve a fast correction for this tilt. By moving the lens of the camera to positions providing a maximum sharpness of at least three regions of interest (ROI) in the image sensor the tilt of the image sensor is calculated by using the correspondent lens/sensor distances and the distances of the different ROIs to the center of the image sensor. Yaw and pitch values of the tilt of the image sensor are calculated to enable an alignment of the sensor.
