Methods, devices, and computer-program products are provided for adding data to a digital video signal in a visually imperceptible manner. For example, a region of pixels can be identified in a video frame, and one or more pixel characteristics of the region of pixels can be determined. Based on the one or more pixel characteristics of the region of pixels, at least one pixel characteristic of a subset of pixels from the region of pixels can be modified in order to encode a set of data into the region of pixels. An output frame can be provided that includes the modified at least one pixel characteristics for the subset of pixels.

According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry obtains time changes in intensity of image signals corresponding to a contrast agent or a blood flow based on at least one of time series contrast image data, time series non-contrast image data, and time series subtraction image data between the contrast image data and the non-contrast image data, generate color image data, having color pixel values based on the time changes in the image signals, according to a color scale, and display frames of the color image data sequentially on a display. The processing circuitry performs a loop playing of the frames of the color image data by sequentially shifting the color scale in a direction of a color phase change, at pixels of the color image data, until an instruction for stopping the loop playing is input from an input circuit.

The present application discloses a novel algorithm to convert medical hyperspectral images (MHSI) into RGB (RedBlueGreen) images in different medical conditions by making use of the three spectral bands (Red, Green and Blue) of the MHSI and mapping them into Red, Green and Blue components for visualization of hyperspectral images.

A display apparatus includes a display driving circuit and a controller. The display driving circuit includes a data driver to sequentially drive a plurality of pixel groups during one horizontal period in a time-division manner. The pixel groups are included in each of the horizontal lines of a display panel. The controller analyzes a pattern of received image data and determines a driving sequence of the plurality of pixel groups of each horizontal line based on a result of the analysis of the pattern of received image data.

A later generation display device may be connected to the video output port of an older electronic device which utilized an earlier generation display such as a dot matrix display. The early generation display is replaced with the later generation display. The display device includes software which receives graphic data through the video output port and identifies which frame is currently being streamed. The display device matches the frame being streamed to a stored graphic frame having a higher resolution and/or color. The matched frame is delivered to the later generation device so that the user can experience a higher quality visual effect by retrofitting the older electronic device with the later generation display.
