Abstract: PROBLEM TO BE SOLVED: To provide a method capable of greatly reducing auto-focus latency within image capture devices including digital still cameras and digital video cameras.SOLUTION: An auto-focus process within an image capture device is performed by predicting a focus value for a scene at a lens position of a lens included in the image capture device on the basis of a corrupt focus value for the lens position calculated from a first frame directly after lens settlement. The auto-focus process determines the size and direction of movement for the lens to a next lens position on the basis of the predicted valid focus value and moves the lens to the next lens position during a second frame, whereby the speed of the auto-focus process is potentially doubled or tripled.

Abstract: PROBLEM TO BE SOLVED: To reduce hand jitters for cameras.SOLUTION: A camera system in a normal mode and a hand jitter reduction (hjr) mode may comprise generating a first exposure time-gain product by multiplying normal mode exposure time and gain together. It may further comprise modifying the normal mode exposure time and gain and modifying these modified parameters to generate a second exposure time-gain product for a hjr mode that reduces the difference between the first exposure time-gain product and the second exposure time-gain product. To reduce the difference, the normal mode frame rate may also be modified. Operation of a camera in normal mode may be in response to a sensed light level being above a threshold. The hjr mode may be selected by a user while the camera is operating. The hjr mode may be used in response to a sensed light level being lower than the threshold.

Abstract: PROBLEM TO BE SOLVED: To select a best focal position.SOLUTION: An auto-focus module 22 may involve calibration of a lens actuator used to move a lens within a search range during an auto-focus process. For example, an image capture device may adjust reference positions for the search range on the basis of lens positions selected for different focus conditions including a far focus condition and a near focus condition. The different focus conditions may be determined on the basis of a detected environment in which the device is used. The image capture device may detect indoor and outdoor environments on the basis of lighting, exposure, or other conditions. Detection of an indoor environment may indicate a likelihood of near object focus, while detection of an outdoor environment may indicate a likelihood of far object focus.

Abstract: In a method for reducing lens vibration in an image capture device, a lens movement requirement is broken up into N smaller lens move steps, and the lens is moved a first of the N smaller steps. A wait time is inserted after completing the first of the N smaller steps, and then the moving and inserting steps are repeated until the remaining N smaller move steps have been completed. The image capture device includes a voice coil motor for moving the lens under control of a controller in accordance with the lens movement requirement, which reflects a determined lens position. The voice coil motor includes springs which impart vibration to the lens during lens movement. The vibration imparted by the springs to the lens is thus actively dampened during the lens movement to the determined lens position.

Abstract: A two-dimensional (2D) mesh is applied over a distortion surface to approximate a lens roll-off distortion pattern. The process to apply the 2D mesh distributes a plurality of grid points among the distortion pattern and sub-samples the distortion pattern to derive corrected digital gains at each grid location. Non-grid pixels underlying grid blocks having a grid point at each corner are adjusted based on the approximation of the lens roll-off for the grid points of the grid block. In one example, bilinear interpolation is used. The techniques universally correct lens roll-off distortion irregardless of the distortion pattern shape or type. The technique may also correct for green channel imbalance.

Abstract: The disclosure relates to techniques for calibration of an auto-focus process in an image capture device. The techniques may involve calibration of a lens actuator used to move a lens within a search range during an auto-focus process. For example, an image capture device may adjust reference positions for the search range based on lens positions selected for different focus conditions. The different focus conditions may include a far focus condition and a near focus condition. The focus conditions may be determined based on a detected environment in which the device is used. Detection of an indoor environment may indicate a likelihood of near object focus, while detection of an outdoor environment may indicate a likelihood of far object focus. An image capture device may detect indoor and outdoor environments based on lighting, exposure, or other conditions.

Abstract: The disclosure describes flicker detection and correction techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes flicker correction techniques that compare different image frames to detect flicker. In some embodiments, the comparison involves summing intensity values associated with rows within the frames and comparing the row sums to generate a difference signal. Detection and correction of flicker may be performed using a first derivative of the difference signal. The first derivative of the difference signal can be used in a variety of ways to detect and correct flicker.
