Abstract
A digital camera with video input is disclosed. An image sensor is provided to capture an image and convert the captured image into R/G/B image signals the are processed by a video signal processing unit for being converted into pixel data having a first format. A TV decoder converts input analog video signals into pixel data having a second format. A scaling unit performs aspect ratio processing and zoom/pan function to pixel data. A TV interface unit converts pixel data having the second format into pixel data having the first format for being selectively output to the scaling unit directly and output to the scaling unit after transferring to the video signal processing unit for performing edge enhancement. A compressing and storage unit performs compress operation to the pixel data output from the video signal processing unit and the scaling unit. An USB unit converts pixel data after being compressed into serial data for output.
