A surgical imaging device includes at least one light source for illuminating an object, at least two image sensors configured to generate image data corresponding to the object in the form of an image frame, and a video processor configured to receive from each image sensor the image data corresponding to the image frames and to process the image data so as to generate a composite image. The video processor may be configured to normalize, stabilize, orient and / or stitch the image data received from each image sensor so as to generate the composite image. Preferably, the video processor stitches the image data received from each image sensor by processing a portion of image data received from one image sensor that overlaps with a portion of image data received from another image sensor. Alternatively, the surgical device may be, e.g., a circular stapler, that includes a first part, e.g., a DLU portion, having an image sensor a second part, e.g., an anvil portion, that is moveable relative to the first part. The second part includes an arrangement, e.g., a bore extending therethrough, for conveying the image to the image sensor. The arrangement enables the image to be received by the image sensor without removing the surgical device from the surgical site.

Devices, methods, and software are disclosed for an adaptive video capture decode system that efficiently manages a stream of image frames between a device display screen and a processor performing decode attempts on decodable features in the image frames. In an illustrative embodiment, a device assigns frames of image data from a stream of frames of image data to either a display subsystem or a decode subsystem. The display subsystem is operative for rendering the frames of image data on a display screen. The decode subsystem is operative for receiving frames of image data and performing an attempted decode of a decodable indicia represented in at least one of the frames of image data. None of the frames of data are assigned to both the display subsystem and the decode subsystem.

A method for continuous electronic zoom in a computerized image acquisition system, the system having a wide image acquisition device and a tele image acquisition device having a tele image sensor array coupled with a tele lens having a narrow FOV, and a tele electronic zoom. The method includes providing a user of the image acquisition device with a zoom selecting control, thereby obtaining a requested zoom, selecting one of the image acquisition devices based on the requested zoom and acquiring an image frame, thereby obtaining an acquired image frame, and performing digitally zoom on the acquired image frame, thereby obtaining an acquired image frame with the requested zoom. The alignment between the wide image sensor array and the tele image sensor array is computed, to facilitate continuous electronic zoom with uninterrupted imaging, when switching back and forth between the wide image sensor array and the tele image sensor array.

A method in a computerized system including an image sensor mounted in a moving vehicle. The image sensor captures image frames consecutively in real time. In one of the image flames, a spot is detected of measurable brightness; the spot is matched in subsequent image frames. The image frames are available for sharing between the computerized system and another vehicle control system. The spot and the corresponding spot are images of the same object. The object is typically one or more of headlights from an oncoming vehicle, taillights of a leading vehicle, streetlights, street signs and / or traffic signs. Data is acquired from the spot and from the corresponding spot. By processing the data, the object (or spot) is classified. producing an object classification. The vehicle control system controls preferably headlights of the moving vehicle based on the object classification. The other vehicle control system using the image frames is one or more of: lane departure warning system, collision warning system and / or ego-motion estimation system.

A method and a device for intra prediction coding and decoding of an image in which the intra prediction according to a selected intra prediction mode based on a direction of an input image is performed are provided. In the method and the device, an input block is frequency transformed, a direction of pixels in the input block is determined, and the intra prediction is performed according to an intra prediction mode that has the most similar direction to the determined direction of the pixels.
