  • Patent number: 11563892
    Abstract: To satisfactorily detect an edge detection signal of a high frequency band from a captured image signal at all times. A filtering unit extracts an edge detection signal of a high frequency band from an image signal obtained from imaging, and a band control unit controls the high frequency band on the basis of lens information. For example, the filtering unit includes a first high-pass filter with a first cutoff frequency, a second high-pass filter with a second cutoff frequency that is lower than the first cutoff frequency, and an ? blending unit that performs ? blending on output of the first high-pass filter and output of the second high-pass filter. Even if the frequency of the edge detection signal included in the captured image signal varies due to a change in a zoom position, a lens model number, an F value or the like, the edge detection signal can be satisfactorily detected at all times.

  • Patent number: 11483460
    Abstract: A camera system may include one or more voice coil motor (VCM) actuators to implement focus, tilt and shift functions. The VCM actuators may include coils segmented into multiple coil segments having individually impedances lower than the impedance of the respective coil as a whole. The coil segments may be individually driven by respective currents at different points in time to interact with magnet(s) to produce motive forces along the same axis. Based on the winding configuration and driving mode of the coil segments, the motive forces may move a lens group relative to an image sensor in a direction substantially orthogonal to an image plane, tilt the lens group relative to the image sensor, or shift the image sensor relative to the lens group on the image plane.

  • Patent number: 11470286
    Abstract: A high sensitivity image sensor with panchromatic and color pixels arranged to enable high sensitivity, efficient binning and minimize aliasing is disclosed. Efficient binning is enabled by composing the color filter array of tiles containing pixels of at most two types, one panchromatic and the other colored, so that like color pixels to be binned are adjacent to each other. Aliasing is minimized by the twin methods of evenly spacing out tiles containing pixels of like color over the image sensor, and optimizing the arrangement of panchromatic and color pixels within each tile if the tile contains both panchromatic and colored pixels. An image sensor with these color filter arrays can be used to realize cameras with high sensitivity and a plurality of resolutions, with the lower resolutions consuming less power, while minimizing alias artifacts in each supported resolution. A variant of this image sensor with both infrared and color pixels is also disclosed.
