Abstract: An image stitching method for use in an image processing apparatus is provided. The method includes the steps of: receiving a first video file and a second video file from an image capturing unit, wherein the first video file includes at least one first image and a first audio track, and the second video file includes at least one second image and a second audio track; calculating delay time between a first acoustic feature of the first audio track and a second acoustic feature of the second audio track to synchronize the first image and the second image; converting the first image and the second image into a first adjusted image and a second adjusted image; and performing an image stitching process on the first adjusted image and the second adjusted image to generate a stitched image.

Abstract: In a digital camera having multiple optical systems, multiple image capturing elements are effectively driven to reduce power consumption. A digital camera has a first image capturing optical system having a lens and a first image sensor and a second image capturing optical system having a lens and a second image sensor. A controller and timing generator selects the image signal from the first image capturing optical system while controlling an operation or power of the second image sensor and a clock driver to be OFF when the zoom position falls within a first zoom range. When the zoom position falls within a second zoom range, the image signal from the second image capturing optical system is selected while an operation or power of the first image sensor and a clock driver is controlled to be OFF. An operation or power of the image capturing optical system which is not selected is stopped so that power consumption is reduced.
