The image processing system 100 may be configured from an external source 110. For example, the external source 110 may include a broadcasting company such as an airwave and a cable TV, and a video service provider that collects and provides images. The video may include various broadcasting videos, such as sports, news, dramas, Programs, movies, etc., but examples of external sources 110 and media data are not limited thereto. The image processing system 100 may perform appropriate processing on the received image data so as to be suitable for processing. For example, when the received image is analog data, it is possible to perform analog-to-digital conversion or to perform decoding on the received image, but the processing on the received image is not limited thereto.

In some embodiments, the image processing system 100 may encode data to be embedded in the image using the color of the pixel used in the received image.

In a further embodiment, the image receiving unit 210 may receive the image in real time so that the image processing system 100 can provide the streaming service to receive, process, and transmit the media data in real time. For example, the image may include, but is not limited to, various broadcast moving images or image files such as sports, news, dramas, entertainment programs, movies, etc., received in real time.

The image received by the image receiving unit 210 may include a plurality of frames. Each frame may include a plurality of rows and a plurality of columns, and each of the plurality of rows and the plurality of columns may include a plurality of pixels. For example, for an image of size 720X400, each frame may have 720 columns and 400 rows, one column may contain 400 pixels, one row may contain 720 pixels, one frame may contain 288000 pixels . In some embodiments, the matrix selector 220 may be configured to select at least one row or column into which data is to be inserted, from among a plurality of rows and a plurality of columns of the image received by the image receiving unit 210.

For example, red may represent 1, green may represent 0, and blue may represent -1. However, the color is not limited to three bits, and it may be four bits or more, or two bits such as black and white. In addition, in addition to the three colors of RGB, the hue may be black, gray, or white, and the hue may be expressed by changing the saturation or brightness of blue. In order to clarify the description, An example of encoding data in color will now be described. Data can be represented by a data encoder 240 as a plurality of cells in 3-bit RGB color.

In some embodiments, the data combining unit 250 may divide the data encoded by the data encoder 240 into at least one row or column selected by the frame selecting unit 230, and combine the data with the image. In a further example, if the frame to which the data is to be combined is selected by the frame selector 230, the data may be combined on the selected frame and the selected row or column.
