摘要： An image processing apparatus includes a depth map generator which generates a depth map of a predetermined image which includes at least one object; a disparity estimator which estimates a reference disparity of a left eye image and a right eye image at a predetermined distance from the object based on the generated depth map; a disparity calculator which calculates a changed disparity of the left eye image and the right eye image at a changed distance by using the estimated reference disparity if the predetermined distance is changed; and a three-dimensional (3D) image generator which generates a 3D image which moves horizontally from the left eye image and the right eye image corresponding to the changed disparity.

摘要： A display apparatus and a method for applying an OSD applying thereto. The display apparatus maintains the depth of the OSD to be displayed on the screen at a specific depth if the depth of a 3D image is adjusted. Accordingly, even if the depth of the 3D image is adjusted, the depth of the OSD remains the same. Therefore, a user may be provided with the OSD of which depth does not change even if the depth of the 3D image is adjusted.

摘要： An apparatus and a method of calculating a channel frequency domain correlation are disclosed in the invention. The apparatus of calculating the channel frequency domain correlation includes: a pilot channel preliminary estimation unit configured to preliminarily estimate a frequency domain channel response at pilot subcarriers of a receiving signal to obtain a pilot channel preliminary estimation value; a determination unit configured to determine a channel frequency domain correlation value which can be reliably calculated; a first channel frequency domain correlation value calculation unit configured to calculate the channel frequency domain correlation value which can be reliably calculated using the pilot channel preliminary estimation value to obtain a reliably calculated channel frequency domain correlation value; and a second channel frequency domain correlation value calculation unit configured to calculate an other channel frequency domain correlation values using the reliably calculated channel frequency domain correlation value. The invention may also effectively apply to calculation of the channel frequency domain correlation and channel estimation.
