A transmission device included in a communication system in accordance with MIPI standards comprising: an image processing circuitry having a Region-Of-Interest mode, in which Region-Of-Interest information of one or more Regions-Of-Interest (ROIs) in an image is transmitted by the image processing circuitry, and a non-Region-Of-Interest mode, in which the Region-Of-Interest information of the one or more Regions-Of-Interest (ROIs) is not transmitted, the image processing circuitry, in the ROI mode, is configured to transmit a first frame of data of an image, the first frame of data including embedded data, Region-Of-Interest information for each image row of a first plurality of image rows of the image, and Region-Of-Interest data for each image row of a second plurality of image rows of the image, the second plurality of image rows including the first plurality of image rows and image rows for which the information included in the Region-Of-Interest information has not changed from the Region-Of-Interest information included in the image row that is caused to be transmitted immediately before, and the image processing circuitry, in the non-ROI mode, is configured to transmit a second frame of data of the image, the second frame of data including all payload data for each image row of a third plurality of image rows of the image, the third plurality of image rows including the second plurality of image rows, and the second frame of data does not include the ROI information and the ROI data, wherein the Region-Of-Interest data for each image row of the second plurality of image rows indicate an image sensing result corresponding to the Region-Of-Interest to be transmitted, and the Region-Of-Interest information for each image row of the first plurality of image rows includes information indicating a position of the image row and a position of a column of one or more Regions-Of-Interest (ROIs) included in the each image row, and wherein the Region-Of-Interest information further includes identification information of the one or more Regions-Of-Interest (ROIs) included in the image row and information indicating a size of the one or more Regions-Of-Interest (ROIs) included in the image row. an image processing circuitry having a Region-Of-Interest mode, in which Region-Of-Interest information of one or more Regions-Of-Interest (ROIs)
