Embodiment Construction

[0044] figure 1 is a block diagram showing the overall structure of the first exemplary embodiment. figure 2 is a block diagram showing the display controller of the first exemplary embodiment. In the following, reference will be made to figure 1 and figure 2 Provide instructions.

[0045] The display controller 10 as the image display control device of the first exemplary embodiment outputs a driving signal for screen display to the electronic paper display 20 which displays a refresh screen before updating and displaying the screen, and the display controller 10 includes a sampling section 11 , a difference detecting section 12 and a driving section 13 . The sampling section 11 inputs a single image data corresponding to one screen of the electronic paper display 20 among a plurality of continuously transmitted image data every specified period. The difference detection section 12 detects a difference amount representing a difference between the previous image data ...

Abstract

The invention relates to an image display control device, an image display device, an image display control method, and an image display control program. To display an image on an electronic paper display properly, even when image data is transmitted continuously from a host of the existing LCD display system, for example. A sampling section inputs a single image data by each prescribed period from a plurality of pieces of continuously transmitted image data corresponding to one screen of the electronic paper display. A difference detecting section detects a difference amount showing a difference between previous image data and latter image data of two pieces of consecutive image data inputted by the sampling section, and determines to perform screen update by using the latter image data when the difference value is equal to or larger than a threshold value. A driving section generates a driving signal of the latter image data and outputs the signal to the electronic paper display, when the screen update is determined by the difference detecting section.

Description

[0001] Cross References to Related Applications [0002] This patent application is based on and claims priority from Japanese Patent Application No. 2009-298047 filed on December 28, 2009, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an image display control device and the like which output a screen display drive signal to an electronic paper display which displays a refresh screen before updating and displaying the screen. Background technique [0004] As a device for displaying content, a content display device for replacing paper has recently been demanded in the market. Examples of such content display devices are: a browser terminal with a display screen size of A5 to A4, which can be used to view news updated over time (for example, the latest newspaper content automatically distributed from a server); and a large advertisement bulletin board, whose It is placed at a train station etc. an...
