  • Patent number: 10277822
    Abstract: An image forming apparatus which is able to shoot high-quality images while improving image stabilization performance. An optical device which corrects for image blurring is moved in a direction different from an optical axis. Focusing is controlled by calculating a shape of a contrast using AF evaluation values at respective positions of a focus lens, which moves in the direction of the optical axis, at predetermined intervals and using a position of the focus lens at which the contrast is at its peak as a position at which a bundle of rays comes to a focus on a light-incident plane of the image pickup device. During the focusing control, positions of the focus lens obtained when the AF evaluation values were obtained or the obtained AF evaluation values are corrected according to detected positions of the optical device in a direction perpendicular to the optical axis.

  • Patent number: 10257456
    Abstract: Embodiments of a virtual frame buffer (VFB) for buffering asynchronous data originating from an imaging source such as a dynamic vision sensor. The VFB may include a hash table memory, a data memory, and a control unit. The control unit receives an input address of an asynchronous data event and determines a pseudo-randomly computed hash of the hash table memory at which to store the input address. The control unit links the hash to a handle corresponding to a data memory cell that stores pixel data of the event. The VFB may interface like a full frame buffer, but use significantly less memory. The VFB may be used with a pixel processing algorithm to search for recent events in a localized environment of a pixel.
