Image display apparatus and image processing apparatus

摘要

An image display apparatus includes: rate multiplication section multiplying frame rate of input image by 2n (n is a natural number), the input image being generated through a process including a frame rate conversion from cinema image to television image, the frame rate conversion being performed so that two consecutive frames of cinema image are treated as a unit; replacement section replacing, with n frames of first image, n frames of second image which come immediately after a switch position from the first image to the second image in a sequence of image frames with a rate multiplied by the rate multiplication section, the first image and the second image corresponding to first half and latter half of the unit of the cinema image, respectively; and display section displaying image outputted from the replacement section.

1. An image display apparatus comprising:
rate multiplication means for multiplying frame rate of input image by 2n (n is a natural number), the input image being generated through a process including a frame rate conversion from cinema image to television image, the frame rate conversion being performed so that two consecutive frames of cinema image are treated as a unit; replacement means for replacing, with n frames of first image, n frames of second image which come immediately after a switch position from the first image to the second image in a sequence of image frames with a rate multiplied by the rate multiplication means, based on (i) a determination, for the sequence of image frames with a rate multiplied, indicating a display time of frames of the first image, the first image corresponding to first half of the unit of the cinema image, is different from a display time of frames of the second image, the second image corresponding to latter half of the unit of the cinema image and (ii) a determination of whether a count value that counts the frames of the first image in the sequence of the image frames with the rate multiplied by the rate multiplication means output from the replacement means is equal to a value that is greater than twice 2n; and display means for displaying image outputted from the replacement means.
