A video processing device () includes: an edge histogram generating section () and a noise reducing section (). The generating section () generates an edge histogram of a decoded image obtained from a video signal. The noise reducing section () (i) determines whether or not a ratio of a sum of frequencies of classes higher than a predetermined class of an edge histogram to a sum of all frequencies the edge histogram is equal to or greater than a predetermined threshold value and (ii) performs a smoothing process on the decoded image with a smoothing intensity adjusted in accordance with whether or not the ratio is equal to or greater than the predetermined threshold value.

There is provided with a color mixing section for mixing yellow to red or green, when red or green is displayed by a liquid crystal television including a liquid crystal panel that has a color filter for four primary colors for red, green, blue and yellow, a backlight that emits light to the liquid crystal panel, and a television signal processing section that converts an inputted color video image signal into signals representing red, green, blue and yellow regarding a color video image.

Liquid crystal display apparatus and liquid crystal television

An image displaying apparatus executes FRC process, wherein image deterioration in a boundary portion between a still image display area and its periphery is prevented. When the magnitude of the motion vector of an object in the periphery of a still image display area is less than a predetermined threshold value, an interpolation frame generation portion defines the pixel values of a still image display area and its periphery of the frame #n as the interpolation pixel values of a still image display area and its periphery of the interpolation frame #I. When the magnitude of the motion vector of the object is equal to or greater than the predetermined threshold value, the pixel values of the still image display area and its periphery of the frame n+1 are defined as the interpolated pixel values of the still image display area and its periphery of the interpolation frame #I.

Image displaying apparatus

A liquid crystal television () includes a backlight () which emits light toward an outside of the liquid crystal television () so that an image is displayed on a liquid crystal panel () and a backlight control circuit () which controls whether or not the backlight () emits light. The backlight control circuit () carries out control with respect to backlight () so that a light-emitting period in which the backlight () emits light alternates with a non-light-emitting period in which the backlight () does not emit light.

Display device and display method

A display device () includes: a display section () which displays a picture; a user specifying section () which specifies a user viewing the display device; an image quality specifying section () which, in a case where the user specifying section () has specified a plurality of users, (i) obtains, from a recording section which records a plurality of setting values that correspond to user information for discriminating the plurality of users and are used to adjust an image quality, the plurality of setting values that correspond to the respective plurality of users thus specified and (ii) specifies, in accordance with the plurality of setting values thus obtained, a plurality of image qualities of a respective plurality of pictures to be displayed in the display section (); and an image quality adjustment instructing section () which instructs an image quality adjusting section () to cause the display section () to display the plurality of pictures at the respective plurality of image qualities thus specified.
