- the variables input video signal InYi, output video signal OutYi, The positive parameter Ri and the position parameter mi
- the variables are appended with a subscript i to indicate that they depend on the pixel i (coordinates (xi, yi)), but are updated in units of frames or regions (feature C, detection limit).
- No suffix i is attached to D).
- the sum of squares (power) of frequency components in a specific region of the input video signal is set as a feature amount C, thereby enhancing the power saving effect.
- the input video signal In Yi in this embodiment is a luminance signal (Y component) in the Yuv color space
- the feature amount C is a frequency obtained by performing a Fourier transform on the input video signal InYi using the following equation.
- cpd is the viewing angle and its full spell is cycle per degree. For example, when the number of horizontal pixels on the display screen is “1024” and the viewing angle is 33 degrees, the maximum value of the spatial frequency is about 15.5 cpd.
- F (w) is the result of Fourier transform of the input video signal InYi.

- Non-Patent Document 1 (“Sensation. Perception Handbook”, SBN—414 30503—9C3011, p. P. 346—348) describes a high luminance region due to the Craik-Obrien illusion when an edge is present on a display screen. Teaching the phenomenon that the brightness of the appearance of the camera decreases. Due to this phenomenon, when there are a plurality of edges on the display screen, the sensitivity of the brightness is relatively lowered in the peripheral region of the edges (in other words, the luminance change is less likely to be ignorable). Also, if there are many edges in the image, the power will increase. Therefore, for images with high power, It is possible to increase the brightness difference between the center and the periphery of the display screen. The present inventors made use of this property and attempted to enhance the power saving effect as compared with the prior art.
- Detection limit D is determined as follows. For a certain image, set the brightness of the center of the display screen to the maximum value “1”. No one feels a change in brightness when the brightness of the display screen is all equal to the maximum value “1” until it reaches the periphery.
- the present inventors repeated subjective evaluation experiments for various images to determine the detection limit D, and summarized the results in a graph as shown in FIG.
- the horizontal axis is the feature amount C (par)
- the vertical axis is the detection limit D. From Fig. 2, it can be seen that the detection limit D tends to decrease as the feature C (power) increases.
- Fig. 2 shows that the feature value C (power) is small V, the absolute value of the slope of the detection limit D is large, and the feature value C (power) is large, and the slope of the detection limit D is absolute in the region. The value is small, indicating that there is a characteristic.
- the feature amount and the detection limit are the power of the input video signal.
- the video display device of the present embodiment is configured as follows.
- the video signal converter 100 converts the input video signal into a video, and stores the result (display data) in the display memory 11 such as VRAM.
- the driver 12 controls the display device 13 based on the display data stored in the display memory 11, and as a result, the display data is displayed on the display screen of the display device 13.
- a self-luminous display (PDP, organic EL, LCD, etc.) is assumed as the display device 13.
- the display device 13 may be a cathode ray tube or the like. In that case, the display memory 11 and the driver 12 can be omitted.
- the video signal converter 100 includes the following elements.
- the color converter 1 is composed of the color space RGB of the input video signal consisting of the components (ui, vi) that are not the brightness component (InYi) and the brightness component.
- v Convert to color space.
- the color reverse converter 10 reversely converts the output video signal OutYi in the Yuv color space to the RGB color space.
- the input video signal and the output video signal are expressed in the RGB color space, and the internal processing of the video signal converter 100 is performed in the Yuv color space.
- the brightness component used in the internal processing of the video signal conversion apparatus 100 may be various brightness components such as the brightness component (Y) of the YCbCr color space. If color space conversion is not required, the color converter 1 or the color inverse converter 10 can be omitted. Note that the conversion formula used by color conversion 1 or color reverse conversion 10 may be a well-known one. The present invention does not have the basic concept of color conversion Z color reverse conversion, so detailed description is omitted.
- the first memory 2 stores the brightness component output by the color change 1 (that is, the input video signal InYi) for one frame
- the second memory 3 stores the brightness component output by the color change 1
- Non-component ie, input video signal ui, vi
- the input video signal InYi stored in the first memory 2 is video-converted by an element described later and output to the color inverse converter 10.
- the input video signals ui and vi stored in the second memory 3 are output to the color inversion as they are.
- the target pixel setting unit 4 sets the target pixel i on the display screen configured by the input video signal InYi, and outputs the target pixel i to the first memory 2 and the position parameter supply unit 5.
- the first memory 2 outputs the input video signal InYi at the target pixel i to the multiplier 9 and the feature amount calculation unit 6.
- the position parameter supply unit 5 supplies a position parameter mi that depends on the target pixel i set by the target pixel setting unit 4.
- the position parameter mi varies depending on the coordinates (xi, yi) of pixel i. Therefore, even when a video signal having the same color for all the pixels is input, the video signal is converted by the position parameter mi, and the converted video signal has a different color depending on the pixel.
- the position parameter supply unit 5 keeps the position parameter mi of the pixel of interest i by the following equation.
- (xO, yO) is the coordinates of the center point PO on the display screen
- ri is the distance between the center point PO (xO, yO) and the pixel of interest i (coordinates (xi, yi))
- K is Gaussian.
- Fig. 3 (a) shows the position parameter mi as an isoline, and when the distribution of the position parameter mi is cut along the line segment pq in Fig. 3 (a), it is shown in Fig. 3 (b). It becomes a Gaussian distribution that is convex upward.
- the feature quantity calculation unit 6 receives the input video signal InYi, and calculates the feature quantity C (power) of the input video signal InYi using (Equation 1) as described above.
- the detection limit setting unit 7 has a data table corresponding to the graph of FIG. 2, and uses this table to set the feature amount C force detection limit D calculated by the feature amount calculation unit 6. That is, the detection limit setting unit 7 corrects the feature amount C.
- the correction parameter setting unit 8 determines the correction parameter Ri based on the position parameter mi supplied by the position parameter supply unit 5 and the detection limit D set by the detection limit setting unit 7 according to the following equation.
- the multiplier 9 corresponds to a conversion unit, converts the input video signal InYi of the pixel of interest i based on the correction parameter Ri determined by the correction parameter setting unit 8 according to the following equation, and is a conversion result: Output video signal OutYi to color inverse converter 10.
- the multiplier 9 outputs one output video signal OutYi, the target pixel setting unit 4 advances the target pixel i by one.
- the correction value Ri is adaptively determined based on the input video signal, so that power consumption can be effectively reduced while maintaining the apparent image quality.
- the feature amount extraction unit 6 updates the detection limit D for each frame, but the feature amount extraction unit 6 detects the detection limit D of the previous frame and the detection of the current frame. Limits may be applied so that the absolute value of the difference from limit D does not exceed a certain value. In this way, flickering of the display screen can be suppressed.
