    Abstract: A display apparatus includes a liquid crystal panel; and a source driver configured to output an image signal to the liquid crystal panel. The source driver may include a digital-to-analog converter (DA converter) configured to convert digital image data into an image signal of normal polarity and an image signal of inversion polarity; a plurality of multiplexers each of which receives the image signal of the normal polarity and the image signal of the inversion polarity from the DA converter, and outputs the image signal of the normal polarity and the image signal of the inversion polarity as they are or cross outputs the image signal of the normal polarity and the image signal of the inversion polarity; and an inversion controller configured to output a control signal to each of the plurality of multiplexers through a plurality of output terminals respectively connected to the plurality of multiplexers. Each of the plurality of multiplexers may be configured to output the image signal of the normal polarity and the image signal of the inversion polarity as they are in response to a first control signal of the inversion controller, and to cross output the image signal of the normal polarity and the image signal of the inversion polarity in response to a second control signal of the inversion controller.

    Abstract: A radiation imaging apparatus and a radiation image display method implemented using the radiation imaging apparatus, may include a display unit to display at least one first radiation image in at least one view area, and a control unit. If the control unit obtains a second radiation image corresponding to a first radiation image selected from the at least one first radiation image, the control unit controls the display unit to display the second radiation image in a view area in which the selected first radiation image is displayed.

    Abstract: An image processing device includes a first wide dynamic range (WDR) image generation block, a control signal generator, and a second WDR image generation block. The first WDR image generation block processes a long-exposure image signal to generate a first image signal, processes a short-exposure image signal using a second weight value to generates a second image signal, and to synthesize the first image signal and the second image signal to generate a first WDR image signal. The control signal generator calculates a difference between the second weight value and a reference weight value and generates control signals according to a result of the calculation. The second WDR image generation block adjusts a noise level of the first WDR image signal using the control signals and generates a second WDR image signal according to a result of the adjustment.
