持される。この値が高彩度部の面積に相当する。Although the B signal is used, signal formats such as Y, R, and B signals may be used. These color signals are each A/D converted (signals after conversion are referred to as r, g, and b), and the high chroma portion extraction circuit 10 It is determined whether the signal level is above a certain signal level or not. The Lr, Lg, and Lb color signals as a result of the determination are "H" signals when the saturation is high, and are counted by each counter 12. Each counter 12 is reset every field period, so - r in the screen

When the Lw flaw signal is "H", the gate circuit 816 opens the gates of each of the g, r, and b signals, and inputs the digital data of the g, r, and b signals to an integrating circuit 17 that integrates each digital data. 'N circuit 17 is reset every field period to obtain the integral value g,

In other words, the count values Nr, Ng, Nb, Nf corresponding to the area of the high chroma part and skin color part of each primary color and the integral values r, g, b of the r, g, b signal levels of the part close to white are calculated for each field period.

Predetermined white balance adjustment data G/B and G/R are output from this data. Depending on this output, the gains of the variable gain amplifiers AI and A2 inserted into the R and B signal input lines of the color reproduction correction circuit 5 are adjusted. Therefore, the R', G, and B' flaw signal gains input to the color reproduction correction circuit 5 are approximately equal to each other. In this way, the ratios of the R, G, and B signals are controlled to be equal for the near-white portion. If there is no near-white part on the screen, press G,
The /B and G/R signals have preset levels, and the variable gain amplifiers AI and A2 also have preset gains.

彩度部のカウント値Ｎｒ。In addition, the CPU 14 outputs data for correcting color reproduction depending on whether there are many high chroma parts and whether there are many skin tone parts from the values of Nr, Ng, Nb, and Nf, and the color reproduction correction time F
Give to #I5. To explain this, the CPU 14 calculates the count value Nr of the high chroma portion.
Ｎｇ、Ｎｂの値から画面内の色分布を判断する。The color distribution within the screen is determined from the values of Ng and Nb.
例えば、Ｎｇの値が所定値より大きく、Ｎｒ、Ｎｂが所
定値以下のときは、画面内に緑色部が多いと判断する。For example, when the value of Ng is greater than a predetermined value and Nr and Nb are less than predetermined values, it is determined that there are many green parts in the screen.
また、Ｎｒ、Ｎｂの値が所定値より大きく、Ｎｇの値が
所定値以下のときは、画面内に黄色部が多いと判断する

定色の影響を受けてＷＢがずれていたり、人物の肌が不
自然になる問題がある。Furthermore, when the values of Nr and Nb are greater than predetermined values and the value of Ng is less than or equal to a predetermined value, it is determined that there are many yellow parts in the screen. As described above, when there are many specific colors in the screen, there is a problem that the WB is shifted due to the influence of the specific colors, and the skin of the person becomes unnatural.
そこで、肌色部のカウント値Ｎｆから肌色部の面積が所
定値以上であれば、肌色部が影響を受けていると判断し
、肌色部の補正を行う。すなわち、高彩度部はより鮮や
かに補正し、また、高彩度部の影響を受ける肌色部は高
彩度部の影響を打ち消すように補正する。Therefore, if the area of the skin-colored portion is equal to or larger than a predetermined value based on the count value Nf of the skin-colored portion, it is determined that the skin-colored portion is affected, and the skin-colored portion is corrected. That is, the high chroma portion is corrected to make it more vivid, and the skin color portion affected by the high chroma portion is corrected so as to cancel out the effect of the high chroma portion.

うにする。Now, let's say that there are many green parts such as leaves on the screen, and the person looks green due to this, and the chromaticity point of green is Gr.
Suppose it was. The figure shows that this is converted to a more vivid green chromaticity point Gr'. On the other hand, the chromaticity point Fa of skin color is converted to the chromaticity point Fa' which looks preferable.

B' is converted into B'', G', B'', and the converted signal is processed by gamma, matrix, etc. in the process circuit 6,
It becomes a video signal.

変換を行う。FIG. 2 shows a specific example of the color reproduction correction circuit 5. In the color reproduction correction circuit FI@5, the input R', G, and B' signals are added to form a W signal. The W signal, R', and B' signals are each A.
After /D conversion, the signals are divided to become R'/W and B'/W signals. Lookup table (LUT) configured in RAM

なってしまい、鮮やかさが再現されない。FIG. 4 is an example of color reproduction when the same situation is photographed using the conventional TTLWB method. The TTLWB method includes a full-screen average method and a white part extraction method. In this case, since the entire screen is greenish due to the reflected light from the leaves, either method will dilute the green color of the entire screen, that is, move the chromaticity point in the direction of the arrow. Note that in the white part extraction method, if there is no white part, WB correction is stopped, but in that case, the screen remains greenish. If the green color of the entire screen is diluted, skin tones will become closer to natural, but even the green of the leaves will become lighter and the vividness will not be reproduced.

It can eliminate the phenomenon where a person's skin color looks unnatural due to the influence of reflected light around the person, and the background color and clothing color can be made brighter.
Yes, it is possible to beautifully reproduce a person's skin.
