Abstract: A method is used with a document camera and an image display device for adjusting the image display range. The document camera includes an image synthesis controller and a graphics buffer. In the method, a first image frame and a second image frame are received by the image synthesis controller. In response to the image parallel display information, the graphics buffer is divided into a first region and a second region, and the image synthesis controller fills partial data of the first image frame and second image frame into the first region and the second region, respectively. In response to a change of the image parallel display information made by the user, the graphics buffer is divided into a third region and a fourth region, and the image synthesis controller fills partial data of the first image frame and second image frame into the third region and the fourth region, respectively.

Abstract: The invention discloses a document camera and a method to make an element distinguished from others on a projected image, the method which implements on the document camera, firstly to capture an image, then to generate a cursor image and paste it onto the image according to a latest relative coordinate of a movement performed by a cursor controller, next to detect whether the cursor image is approximate to an element with a closed contour on the image, when an element with closed contour is detected, then to make the element distinguished from others on the image; eventually, to output the image with the distinguished element.

Abstract: A document camera is used to show image of an object on a display. In the document camera, a first image data of the object obtained by a video-capturing device is derived into a second image data and a third image data by an image processor in response to a zoom operation, wherein the second image data results in a zoomed image of the object and the third image data results in a scaled image of the object. In response to the zoom operation, there is also a mark frame data generated by a position information controller, which results in a mark frame. The zoomed image, scaled image and mark frame are then synthesized into a combined image by an image synthesizer, and the mark frame superimposes the scaled image to indicate a result of the zoom operation.

Abstract: A projecting device capable of synchronously encoding images and sounds into an AV play file includes a receiving unit, a first processing unit, a projecting unit, a sound-recording unit, a second processing unit and an AV encoding unit. The receiving unit receives and outputs a first video signal. The first processing unit receives the first video signal to output a second video signal. The projecting unit receives the second video signal and projects a corresponding image onto a wall. The sound-recording unit records sounds of a user as explaining the image and outputs a first audio signal accordingly. The second processing unit receives the first audio signal to output a second audio signal. The AV encoding unit receives and synchronously encodes the second video signal and the second audio signal into an AV synchronous play file.

Abstract: A document camera is used to show image picked up from an object and/or image received from an external apparatus such as a computer on an image display. In the document camera, an image sensing and processing device senses image of an object and processing the image into an image signal. A display controller controls the display of the image signal. An image synthesizer combines a first image signal received from an external apparatus with a second image signal received from the image sensing and processing device and has images represented by the first image signal and the second image signal simultaneously displayed under the control of the display controller.

Abstract: The present invention relates to a digital image zoom system. The digital image zoom system includes an image sensor, an A/D converter and an image processor. The image sensor senses the object images, wherein the sensing capacity of the image sensor is larger than the resolution of the display. The A/D converter converts the object images into digital images. The image processor retrieves a zoom image from the digital images and produces the zoom image having different sensing resolution according to the sensing capacity of the image sensor.
