METHODS FOR GENERATING VIDEO AND MULTIPLE STILL IMAGES SIMULTANEOUSLY AND APPARATUSES USING THE SAME
Publication number: 20140078343Abstract: An embodiment of a method for generating multiple still images and a video file in parallel is disclosed. A first series of images from an image sensor is provided to at least one buffer. A second series of images are captured in response to reception of a user input for performing a multi-capture operation. The process further provides the first series of images from the buffer for processing along at least two processing paths concurrently with the capturing of the second series of images. The two processing paths then process the second series of images, and the processed first series of images and second series of images are stored into a memory unit. At least one of the processing paths processes only a predetermined portion of the first series of images and the second series of images. Images processed by each of the two processing paths are stored, respectively.Type: ApplicationFiled: September 6, 2013Publication date: March 20, 2014Applicant: HTC CorporationInventors: Chen-Si DAI, Fu-Chang TSENG, Symon J.
