An image processing device () is configured such that an edge histogram creating section () calculates interproximal pixel luminance difference for each of pixels constituting a frame, and a first ratio, which is a ratio of pixels whose interproximal pixel luminance difference is greater than or equal to a first threshold, and an edge enhancement section () performs edge enhancement in such a way that a shoot component to be added is smaller for a frame having a larger first ratio.

Image processing device and image processing method

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.

Image processing device, moving-image processing device, video processing device, image processing method, video processing method, television receiver, program, and recording medium

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.

Display device, television receiver, display device control method, programme, and recording medium

A television receiver for content with which genre information is associated includes: a basic picture quality information receiving section which associates, with a single piece of genre information, a plurality of candidates for picture quality information regarding the content with which the genre information is associated, and which receives basic picture quality information indicating which one of the plurality of candidates is based on; a picture quality correction information creating section which receives picture quality correction information for further correcting the picture quality, and which creates, in accordance with the basic picture quality information and the picture quality correction information, information for correcting the picture quality; and a picture processing section which corrects the picture quality and which creates a picture to be displayed by a liquid crystal display device.
