An apparatus for device motion aware temporal denoising includes a processor and a memory that stores code executable by the processor to receive video data comprising a sequence of video frames that includes a current frame and one or more preceding frames captured by a video capture device that functions as a camera of a portable electronic device. In various examples, the code causes the processor to determine one or more camera motion compensation adjustments to apply to the one or more preceding frames of the sequence based on one or more non-imaging device motion sensor measurements for the video capture device and to generate a sequence of camera-motion compensated preceding frames by applying the one or more camera motion compensation adjustments to the preceding frames of the sequence. A method and a computer program may perform the functions of the apparatus.

A vibration type actuator control apparatus, which uses a vibration from a vibrator to move a contact member, includes a control unit and a drive unit. The control unit includes first and second learned models, each having a neural network, and outputs control amounts for the drive unit to move the contact member. When a contact member moving target velocity is input, the first learned model outputs a first control amount as one of the control amounts. When a positional deviation is input, the second learned model outputs a second control amount as one of the control amounts. The drive unit moves the contact member using a value based on the first and second control amounts. The positional deviation is in association with a difference between a target position for moving the contact member and a detected position detected when the contact member is moved relative to the vibrator.
