Image display apparatus and image display method

摘要

When the degree of reliability of a motion vector is equal to or higher than a threshold, an interpolated image is generated, and the image of a frame of interest and the interpolated image are output to a panel in the order named. Every time the image is output, a backlight is turned on. When the degree of reliability is lower than the threshold, the image of the frame of interest is output twice to the panel. Every time the image is output, the backlight is controlled to alternately set its light amount to the first light amount and the second light amount smaller than the first light amount.

主权项

1. An image display apparatus including a display screen with a backlight, comprising:
an input unit configured to input each frame forming a moving image; an obtaining unit configured to obtain a motion vector between frames inputted by said input unit; a first determination unit configured to determine whether the reliability of the motion vector obtained by said obtaining unit between a first frame and a second frame is larger than a threshold; a second determination unit configured i) to determine, as an intermediate frame to be displayed between the first and second frames, an interpolation frame being generated based on the motion vector and images of the first and second frames in a case where the reliability is larger than the threshold, and ii) to determine, as the intermediate frame, an image frame being based on not an image of the second frame but on an image of the first frame in a case where the reliability is not larger than the threshold; and a control unit configured i) to control the backlight to emit light at a brightness being based on an image of the interpolation frame so as to display the interpolation frame as the intermediate frame in a case where the reliability is larger than the threshold, and ii) to control the backlight to emit light at a darker brightness than the brightness upon displaying the first frame so as to display the image frame as the intermediate frame in a case where the reliability is not larger than the threshold.
