摘要： A low frequency component image L[i] and high frequency component-emphasized image SH[i] are generated from an image A[i]. Lossy compression processing is performed for the low frequency component image L[i] to generate a compressed image C[i] and store it in a memory. A compressed image C[i−1] is decoded to generate a decoded image L′[i−1]. The compressed image C[i] is decoded to generate a decoded image L′[i]. A difference image E[i] between the decoded image L′[i] and the low frequency component image L[i] is generated. The low frequency component image L[i], decoded image L′[i−1], and difference image E[i] are composited at a predetermined ratio to generate a composite image SL[i]. The high frequency component-emphasized image SH[i] and composite image SL[i] are output as subframe images of the i-th frame.

To accomplish this, a display apparatus of the embodiment replaces at least one of a plurality of frame images obtained by doubling the frame rate, with a different image before display. Specifically, the display apparatus replaces at least one of the double-speed converted plural frame images with a high-frequency emphasized image and at least one with a low-frequency component image, and displays the frame images. Furthermore, the display apparatus replaces an image at the border between cinema images with a different image before displaying.

摘要： A display device that receives an input of video signal data including a plurality of pieces of frame data, corrects frame data representing a frame to be displayed based on frame data of a frame adjacent to the frame to be displayed, and outputs the resulting data as data to be displayed on a liquid crystal panel. The device comprises a memory unit adapted to store input frame data. The device determines a correction address used to determine a frame correction amount by comparing the stored frame data and frame data that is currently input; determines correction data that represents a correction amount of the frame data based on the stored frame data and the correction address; and corrects the frame data by adding and/or subtracting the correction amount represented by the correction data to or from the stored frame data.
