By a News Reporter-Staff News Editor at Electronics Newsweekly -- A patent by the inventor Cho, Hyunduk (Seongnam-si, KR), filed on April 29, 2010, was published online on August 12, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8804009 is assigned to Samsung Electronics Co., Ltd. (Gyeonggi-Do, KR).

The following quote was obtained by the news editors from the background information supplied by the inventors: "Example embodiments relate to a multimedia information appliance including a camera unit, an image display unit, and a multi-port memory, and particularly, to a multimedia information appliance including a camera unit, an image display unit, and a multi-port memory, which can reduce a total number of components of the multimedia information appliance and improve performance.

"As the mobile communication terminals become increasingly multi-functional, secondary functions such as camera and multimedia playback, along with an improved wireless communication function are being added to mobile communication terminals. The application, features and functionality of the camera are increasingly expanding through improvements in display screen of a mobile communication terminal and high-speed communication. As a result, a number of mobile communication terminals equipped with cameras is steadily increasing, and the performance (e.g., number of pixel) of the camera modules mounted in the mobile communication modules are steadily improving.

"Hereinafter, an internal configuration of a conventional camera unit including a camera module and an application processor in a multimedia terminal is described with reference to FIG. 1.

"Referring to FIG. 1, a conventional camera unit 50 includes a lens 10, an image sensor 20 that senses optical signals of an image photographed by a camera and converts the optical signals into electrical signals and outputs the electrical signals, an Image Signal Processor (ISP) 30 that converts the electrical signals output from the image sensor 20 into image signals, and an application processor 40 that receives the image signals from the ISP 30 and processes the image signals.

"The camera unit additionally includes a frame memory 31 that stores various parameters necessary to control data processed in the ISP 30 and the image sensor 20 and a frame memory 41 that stores data processed in the application processor 40. Accordingly, the conventional camera unit 10 and a multimedia information appliance including the camera unit 10 include two (or more) frame memories 31 and 41."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "According to an example embodiment of the inventive concepts, a camera unit includes an image sensor configured to receive an optical signal of a photographed image from a lens and configured to convert the received optical signal into an electrical signal; an image signal processor configured to convert the electrical signal into an image signal and configured to control the image sensor; an application processor configured to process the image signal; and a multi-port memory including a plurality of data input/output ports, the multi-port memory configured to receive the image signal from the image signal processor and the application processor using different data input/output ports of the plurality of data input/output ports.

"According to an example embodiment of the inventive concepts, the multi-port memory includes a first port electrically connected to the image signal processor; a second port electrically connected to the application processor; a first port bank electrically connected to the first port and configured to store data; and a second port bank electrically connected to the second port and configured to store data.

"According to an example embodiment of the inventive concepts, the multi-port memory further includes a third port connected to the application processor.

"According to an example embodiment of the inventive concepts, the multi-port memory includes a first port configured to receive parameters that control data processed in the image signal processor and the image sensor from the image signal processor; a second port configured to receive data processed in the application processor; a first port bank storing the data control parameters received from the first port; and a second port bank receiving and storing the data processed in the application processor.

"According to an example embodiment of the inventive concepts, the multi-port memory further includes a third port configured to receive data processed in the application processor.

"According to an example embodiment of the inventive concepts, a multimedia information appliance includes an image sensor configured to receive an optical signal of a photographed image from a lens and configured to convert the received optical signal into an electrical signal; an image signal processor configured to convert the electrical signal into an image signal and configured to control the image sensor; an application processor configured to process the image signal; a multi-port memory including a plurality of data input/output ports, the multi-port memory configured to receive the image signal from the image signal processor and the application processor using different data input/output ports of the plurality of data input/output ports; and an image display unit configured to display an image on a screen based on the processed image signal and a control signal received from the application processor included in the camera unit.

"According to an example embodiment of the inventive concepts, the image display unit includes a controller configured to control the processed image signal and the control signal received from the application processor; a driver configured to output a data signal and a gate signal in response to the processed image signal and the control signal received by the controller; and a display panel configured to display the image in response to the data signal and the gate signal.

"According to an example embodiment of the inventive concepts, the controller receives the processed image signal from the multi-port memory.

"According to an example embodiment of the inventive concepts, the multi-port memory includes a first port electrically connected to the image signal processor; a second port electrically connected to the application processor; a third port electrically connected to the controller; a first port bank electrically connected to the first port and configured to store data; a second port bank electrically connected to the second port and configured to store data; and a third port bank electrically connected to the third port and configured to store data.

"According to an example embodiment of the inventive concepts, the multi-port memory further includes a fourth port connected to the application processor.

"According to an example embodiment of the inventive concepts, the multi-port memory includes a first port configured to receive parameters that control data processed in the image signal processor and the image sensor from the image signal processor; a second port configured to receive data processed in the application processor; a third port configured to receive data supplied to the controller; a first port bank storing the data control parameters received from the first port; a second port bank receiving and storing the data processed in the application processor; and a third port bank receiving and storing the data supplied to the controller.
