A display apparatus and a driving method thereof capable of assuring reliability in frame inversion driving and improving cinema video image quality are provided. 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.

Display apparatus and driving method thereof

This invention enables, for example, reduction of motion blur in a hold-type display device and reduce flicker in an impulse-type display device by a simple process. For this purpose, an LPF filters a frame of input image data (A[i]) to generate low-frequency image data (L). A subtractor and an adder generate high-frequency image data (SH). Another adder adds the low-frequency image data (L) from a delay circuit to subsequent low-frequency image data. A divider halves the sum to generate low-frequency averaged image data (SL). A switch alternately outputs the high-frequency image data (SH) and the low-frequency image data (SL) every time a frame of image data is input. As a result, the apparatus of this invention can generate output image data having a frame rate twice that of the input image data.

Information processing apparatus and control method thereof, and computer program

In order to distribute low-frequency component image data L in image data for one frame to first and second sub-frames respectively as Land L, a distribution of Lin the low-frequency component image data L is decided. This decision is made based on a non-linear curve, so that when the low-frequency component image data L falls within a low-level region, a distribution rate of Lis decreased, and when the low-frequency component image data L falls within a high-level region, the distribution rate of Lis increased within a range that does not exceed 0.5. In this way, a negative-side clipping phenomenon of high-frequency components is suppressed in the low-level region, and flickers are suppressed in the high-level region.
