摘要： Deterioration of the image quality of a moving image which is deteriorated due to a motion-compensated frame rate conversion (FRC) processing is prevented. An image display device comprises an FRC portion (10) for converting the number of frames of an input image signal by interpolating an image signal to which the motion compensation processing is performed between frames of the input image signal and a controlling portion (15) for controlling the operation of the FRC portion (10) after determining whether or not the degree of deterioration of the input image signal is equal to or higher than a predetermined value. The FRC portion (10) comprises a motion vector detecting portion (11e) for detecting a motion vector between frames of the input image signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion (12d) for generating an interpolating frame from the interpolating vector. If the degree of deterioration of the input image signal is equal to or higher than a predetermined value, the controlling portion (15) makes the motion compensation of the FRC portion (10) ineffective by setting the motion vector detected by the motion vector detecting portion (11e) to a zero vector.

摘要： It is an object to prevent the image quality deterioration of a moving image likely to include a plurality of the same consecutive images such as a movie video and an animation video due to the motion-compensated frame rate conversion (FRC) processing. An image displaying device is provided with an FRC portion (10) for converting the number of frames in an input image signal by interpolating an image signal to which a motion compensation processing has been given between the frames in the input image signal, a genre determining portion (14) for determining whether the input image signal is a predetermined genre, and a controlling portion (15). The FRC portion (10) includes a motion vector detecting portion (11e) for detecting a motion vector between the frames of the input image signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion (102) for generating an interpolating frame from the interpolating vector. In the case that the input image signal is relating to a movie or animation, the control portion (15) set the motion vector detected by the motion vector detecting portion (11e) to zero-vector to make the motion compensation processing of the FRC portion (10) ineffective.

摘要： A liquid crystal display apparatus enables image display with optimum quality corresponding to the genre of an image to be displayed. The liquid crystal display apparatus controls the emission luminance of a backlight according to the APL of an image signal measured at an APL measuring portion 14. Upon emission luminance control, the display apparatus sets the follow performance of a change of the backlight emission luminance in following a change in a characteristic quantity of the image signal according to a genre so that the display image can be viewed without an odd feeling. Specifically, the APL of the image signal measured at the APL measuring portion 14 is put into a filter 15, and the rate of a change in the APL on the time axis is controlled through weighted averaging to control the follow performance of the emission luminance control on the backlight. At this time, the genre of image to be displayed is determined, and a constant used for weighted averaging on the filter 15 is changed according to the determined genre to optimize display quality for each genre.
摘要翻译：液晶显示装置使得能够以与要显示的图像的类型对应的最佳质量的图像显示。液晶显示装置根据在APL测量部分14测量的图像信号的APL来控制背光的发光亮度。在发光亮度控制时，显示装置根据类型设置跟随图像信号的特征量的变化的背光发光亮度的变化的跟随性能，从而可以无奇怪地看到显示图像。具体地说，将在APL测量部分14测量的图像信号的APL放入滤波器15中，通过加权平均来控制APL在时间轴上的变化率，以控制发射亮度控制的跟随性能在背光上。此时，确定要显示的图像的类型，并且根据确定的类型改变用于滤波器15上的加权平均的常数，以优化每种类型的显示质量。
