Embodiment Construction

[0026] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement, numerical representation and numerical values ​​of the components described in these embodiments do not limit the scope of the present invention unless otherwise specified.

[0027] (Example)

[0028] figure 1 is a block diagram showing an example of a schematic configuration of a frame rate conversion device according to an embodiment of the present invention.

[0029] The frame rate conversion device includes a computer. A computer includes a main control unit such as a CPU, and storage units such as ROM (Read Only Memory) and RAM (Random Access Memory). The computer may also include, for example, an input / output unit such as a display or a touch screen, and a communication unit such as a network card. It should be noted that these constituent elements are connected via a bus or the like, an...

Abstract

A frame rate conversion apparatus for performing frame rate conversion upon distributing an input-frame into a plurality of sub-frames detects the degree of motion of an image in the input-frame, determines the amount of distribution of the plurality of sub-frames in accordance with the detected degree of motion, and distributes and outputs the plurality of sub-frames in accordance with the determined amount of distribution.

Description

technical field [0001] The present invention relates to a frame rate conversion device and a frame rate conversion method for converting the frame rate of an input image (input frame). Background technique [0002] Display devices are broadly classified into pulse type or hold type according to their display characteristics. Such as Figure 12B A device such as a liquid crystal panel shown to maintain display almost uniformly during one frame period is called a hold type display device. Instead, as in Figure 12A A device shown to have a short lighting period in one frame is called an impulse type display device. [0003] Impulse type display devices include CRT (cathode ray tube) and field emission type displays. In an impulsive display, the pixels flash repeatedly, so the display has flicker-inducing properties. That is, the picture appears to flicker. The higher the luminosity and the larger the area, the easier it is to detect flicker. With the recent trend towards...
