Abstract
In one embodiment of the invention, a digital zoom and panning system for digital video is disclosed including an image acquisition device to capture digital video images; an image buffer to store one or more frames of digital video images as source pixels; a display device having first pixels to display images; a user interface to accept user input including a source rectangle to select source pixels within frames of the digital video images, a destination rectangle to select target pixels within the display device to display images, and a region of interest within the digital video images to display in the destination rectangle; and a digital mapping and filtering device to selectively map and filter source pixels in the region of interest from the image buffer into target pixels of the display device in response to the user input.

38. A digital zoom and panning system, the system comprising:
-
an endoscopic camera device to capture digital video images of a surgical site; an image buffer coupled to the endoscopic camera device, the image buffer to store one or more frames of the digital video images as source pixels; a first display device having first pixels to display images; a first user interface displayed on the first display device to accept a first user input to display a fovea, the first user input including selection of a first source pixel array of source pixels within a first frame of the digital video images with reference to the surgical site and selection of a first target pixel array of target pixels within a subset of the first pixels of the first display device; and a first digital mapping and filtering device coupled between the image buffer and the first display device, and based on the first user input, the first digital mapping and filtering device to selectively map and filter source pixels in the first source pixel array from the image buffer into target pixels in the first target pixel array to display the fovea on the first display device. - View Dependent Claims (39, 40, 42, 43, 44, 45)

41. The digital zoom and panning system of claim 41, wherein
the first digital mapping and filtering device digitally pans from the first source pixel array to a second source pixel array, one or more source pixels outside the first source pixel array are brought within the second source pixel array and one or more source pixels within the first source pixel array are moved outside the second source pixel array.

46. A digital zoom and panning method for digital video, the method comprising:
-
capturing digital video images of a surgical site with an endoscopic camera device; storing one or more frames of the digital video images as source pixels; displaying images on a first display device, the first display device including a first plurality of pixels to display the images; accepting a first user input through a first user interface displayed on the first display device, the first user input to selectively display a fovea on the first display device, the first input including a selection of a first source pixel array of source pixels within frames of the digital video images and a selection of a first target pixel array of target pixels within the first display device to display images; selectively mapping and filtering source pixels in the first source rectangle from the image buffer into the target pixels in the first target pixel array within the first display device. - View Dependent Claims (47, 48, 49, 50)
