PINCH-TO-ZOOM VIDEO APPARATUS AND ASSOCIATED METHOD
First Claim
1. A portable communications device comprised of:
- a touch-sensitive display device (display device) having a first number of rows of picture elements and a second number of columns of picture elements, the picture elements being configured to emit light to generate an image, the display device configured to display video that is embodied as successive and temporally-adjacent frames of images, each image frame being comprised of a first number of image element rows and a second number of image element columns, a plurality of image elements of each image frame being displayed by the display device by corresponding picture elements;
a processor coupled to the touch-sensitive display device, the processor being configured to detect an input gesture on the touch-sensitive display device, and configured to add new image elements to, and subtract image elements from, image frames obtained from a video data memory coupled to the processor, added and subtracted image elements increasing or decreasing respectively, the size of at least a portion of each image subsequently displayed by the display device picture elements, the number of picture elements added to video image frames and the number of picture elements subtracted from video image frames being determined responsive to the input gesture.

Abstract
Full-motion video displayed on a portable communications device such as a tablet personal computer, can be processed “on the fly” to provide a “zoom-in” and “zoom-out” functionality. Image elements are added to video image frames as they are read out from memory and prior to being display on the picture elements (pixels) of a display device in order to make objects depicted in an image file as being larger than how it appears in the original image file. Similarly, image elements are subtracted or deleted from video image frames as they are read from memory and prior to their being displayed in order to make objects depicted in the image frames as being smaller. Video from any source can be zoomed in and zoomed out.

9. A portable communications device comprised of:
-
a touch-sensitive display device having a maximum viewable image size, video displayed on the display device being comprised of a series of temporally-adjacent images, each temporally-adjacent image being comprised of picture elements that are displayed within at least part of the maximum viewable image size; a video data receiver, configured to receive previously-captured video data; a video data storage device coupled to the video data receiver and the touch-sensitive display device, the video storage device being configured to store previously-captured video data for playback on the touch-sensitive display device; and a processor coupled to at least the touch-sensitive display device and configured to receive from the touch-sensitive display device, a tactile selection of a portion of the maximum viewable image size, the processor being additionally configured to at least partially fill the maximum viewable image size of the display device with at least part of the selected portion of the viewable image.
-
- 10. The portable communications device of claim 10, wherein the tactile selection of a portion of the maximum viewable image size is comprised of a rectangular-shaped region of an at least one image displayed within the maximum viewable image size and wherein the processor is additionally configured to generate picture fill elements which are used to at least partially fill the maximum viewable image size.
-
14. A method of displaying video on a portable communications device having a touch-sensitive display device capable of displaying video by generating and displaying a plurality of successive images, the touch-sensitive display device comprised of a first number of image display elements, the method comprised of:
-
receiving image data, which represents a series of temporally-adjacent images recorded by an image capture device; generating video on the touch-sensitive display device, by displaying a series of temporally-adjacent images using the received image data; selecting a portion of at least one displayed image of the series of temporally-adjacent images by a tactile input to the touch-sensitive display device; and generating and adding new picture elements to picture elements within the selected portion of the at least one displayed image of the series of temporally-adjacent images. - View Dependent Claims (15, 16, 17, 18, 19, 20)
