Apparatus and method for overlaying image in video presentation system having embedded operating system
First Claim
1. A video presentation system consisting of:
- a display unit; and
a video presenting device connected to the display unit, the video presenting device consisting of a video presenting unit and an embedded OS unit,wherein the video presenting unit processes a picked-up image and a received image to generate an image signal relative to an overlaid combination of the picked-up image and the received image, the video presenting unit outputting the signal to the display unit, andwherein the embedded OS unit transmits to the video presenting unit the received image and overlay information for configuring the overlaid combination by overlaying one of the picked-up image and the received image on the other one of the picked-up image and the received image.

Abstract
A video presentation system is provided for outputting a document and/or multimedia image file as well as a live image on one display unit. The system integrates an embedded system for controlling devices with a video presentation device, which is an optical image electronic device. The video presentation system integrating an embedded operating system (OS) includes: a video presenting unit processing a generated first image or a received second image to generate a signal that can be displayed, and outputting the generated signal, or processing the first image and the second image to generate a signal that can be displayed, by overlaying the images, and transmitting the captured first image or a part of the image; and an embedded unit transmitting the overlay information and the second image to the video presenting unit through periodic communication with the video presenting unit, and receiving the captured first image.

10. A method of overlaying images using a video presentation system including a video presenting unit and an embedded OS unit integral with the video presenting unit, the method comprising:
-
the video presenting unit capturing a live image; the embedded OS unit receiving and storing a second image from the outside; receiving from a user input device connected to the video presenting unit or the embedded OS unit an image overlay signal for initiating an image overlay according to the live image and the second image; based on the image overlay signal, setting one of the live image and the second image as a main image and the other one of the live image and the second image as a sub image; the embedded OS unit transmitting to the video presenting unit overlay information including a size and position of the sub image; the video presenting unit combining the live image and the second image according to the overlay information; the video presenting unit outputting to a display unit a video signal that contains the live image and the second image being in an overlaid configuration. - View Dependent Claims (11, 12, 13, 14)

15. A method of overlaying images using a video presentation system including a video presenting unit and an embedded OS unit integral with the video presenting unit, the method comprising:
-
the video presenting unit capturing a live image; the embedded OS unit receiving and storing a second image from the outside; receiving from a user input device connected to the video presenting unit or the embedded OS unit an image overlay signal for initiating an image overlay according to the live image and the second image; based on the image overlay signal, setting one of the live image and the second image as a main image and the other one of the live image and the second image as a sub image; the video presenting unit displaying the main image on a display unit connected to the video presenting unit; based on the image overlay signal, the embedded OS unit commanding the video presenting unit to display on the display unit a virtual window over a portion of the main image; and the video presenting unit displaying the sub image in the virtual window. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
