    Abstract: An actuator includes a first damper member and a second damper member that couple a movable body and an immovable body and each include a gel member in a tubular form. The gel member has a first end face and a second end face that are different from each other in cross-sectional shape. The first damper member and the second damper member are oppositely oriented in the axial direction, and are opposite from each other in position of the first end face and the second end face. Consequently, the characteristic variance due to the difference in the direction, in which the movable body moves, is reduced or removed in the actuator as a whole, even if each single damper member is involved with such characteristic variance.

  • Patent number: 11223787
    Abstract: An imaging section includes a plurality of pixel output units that receive subject light that enters without going through an imaging lens and a pinhole. Output pixels of at least two of the plurality of pixel output units differ in incident angle directivity as a result of modulation of the incident angle directivity based on the incident angle of the subject light. A defective pixel detection section detects a defective pixel of the imaging section on the basis of pixel outputs of the imaging section. The defective pixel detection section discriminates a defective pixel that has produced a pixel output whose signal level is larger than or smaller than a threshold range. The image conversion section performs restoration computations by using pixel outputs generated for the respective pixels other than that of the defective pixel and a coefficient set stored in the coefficient storage section, thus generating a restored image.

  • Patent number: 11212462
    Abstract: Methods and apparatus for detecting and correcting for lens tilt in cameras. The common mode signal may be derived from autofocus position (AP) sensors and used as a measure of the autofocus position of the lens on the Z axis. The differential mode signal may also be derived from the AP sensor signals. The differential mode signal may indicate that the lens is or is not tilted, and if tilted may indicate the direction and magnitude of the tilt. The differential mode signal may be used to apply a tilt correction transform to image data based on the strength and direction of the signal. The differential mode signal may also be used to translate the lens on an axis orthogonal to the Z axis to partially correct for lens tilt to align the image plane with the photosensor.
