Problems solved by technology

[0007] However, in the technology described in Patent Document 1 above, since the speed of dimming change has nothing to do with the scene change of the image, when there is no scene change, the dimming On the contrary, when the scene changes sharply, the dimming cannot follow
In addition, in the technique described in Patent Document 2, since the control characteristics of the light source are the same as those of the image signal, the light source and the image may not visually match each other.
In addition, in the technique described in Patent Document 3, it is difficult to appropriately suppress flicker caused by dimming

Embodiment 2

[0163] Next, Embodiment 2 of the present invention will be described. In the first embodiment described above, a plurality of filtering processes are performed by a plurality of circuits (processing units), but in the second embodiment, a plurality of filtering processes are performed using one circuit. Specifically, in Embodiment 2, by switching the input and output signals of the filter operation circuit and the filter coefficients used by the filter operation circuit, one filter operation circuit performs the filter processing on the backlight brightness K and the image correction amount Gy filtering processing. That is, a circuit that performs filter processing on the backlight luminance K and a circuit that performs filter processing on the image correction amount Gy are also used, and filter processing is performed sequentially.

[0164] Figure 9 It is a block diagram showing a schematic configuration of a filter processing unit according to the second embodiment. Th...

Abstract

The invention provides a visual display unit which is used for backlit and depreciation of lamp of electricity saving and prevents flicker of the display image properly when revising the image. The visual display unit revises the image data and controls the luminance of the light source. The scene variation detects the scene variation of a unit detection image data; the image revising unit revises the image data and the luminance control unit controls the luminance of light source. Besides, a time response control unit changes the first time response of the luminance and the second time response of the image correction, as well as having filtration treatment according to the scene variation. Thus, the time response used by the luminance and the image correction is changed according to thescene variation, thereby effectively controlling the flicker and delayed response when in backlit and image correction.

Description

technical field [0001] The present invention relates to an image display device for processing input image data, an image display method, an image display program, a recording medium for recording the image display program, and electronic equipment. Background technique [0002] Conventionally, in an image display device such as a notebook computer using a non-luminous display device such as a liquid crystal screen, when there is no power supply from the outside, the light source (for example, a cold cathode tube) converts the power supplied from the battery into light, and controls the transmission. The amount of light passing through the LCD screen is displayed. Generally, the power consumed by the light source accounts for a large proportion of the power consumed by the entire device. Therefore, the power consumption of the device is reduced by reducing the amount of light generated by the light source (hereinafter referred to as "light source light amount") during batt...
