Image photographing device and image photographing method

The present invention is an image photographing apparatus and an image photographing method capable of forming a color image of a subject in the dark.

In the past, a method for forming a color image of a subject in the dark is an analog color scale display using an infrared image. That is, the intensity level of the infrared intensity distribution obtained from the infrared rays reflected from the object is divided into a plurality of level intervals, and an appropriate color is assigned to each intensity level section to form a color image and displayed, but the analog color code is displayed. Although the display is effective in extracting a certain intensity level range, it is not natural and difficult to identify.

On the other hand, an infrared color image forming apparatus has been proposed which has an infrared camera which receives infrared rays from an object radiated or reflected to obtain an infrared spectrum image, and can store color and infrared spectrum radiation intensity or infrared spectrum reflectance in advance. The first processing means for determining the color of each position of the infrared spectrum image from the respective values of the infrared spectrum radiation intensity or the infrared spectrum reflectance of each position of the infrared spectrum image based on the corresponding data, and the first processing means according to the first The color information obtained by the processing means is a second processing means for artificially coloring each position of the image of the object. (Please refer to Patent Document 1)

However, in the infrared color image forming apparatus of Patent Document 1, it is necessary to prepare the corresponding data of the color in the visible light region of the image object and the infrared spectrum radiation intensity or reflectance in advance by the spectroscopic side, and the difference from the present invention. At least the present invention does not require a color of a memory device that compares such corresponding data, memorizes such corresponding data, and corresponding data that requires processing time.

On the other hand, the prior art proposes an infrared light source having a light-emitting distribution in the infrared field, and a lens type, a light-receiving element having a light-sensing property in the infrared field and a visible field, and a matrix-type CCD sensor, and penetrating respective specific wavelength fields. An infrared imaging device that is different from the infrared light in a specific wavelength region and is attached to a plurality of color filters of the light-receiving element, and an infrared penetrating filter that removes visible light and penetrates the infrared rays, and according to the above picture The imaging signal generating means for generating an imaging signal by the infrared ray of the sensor, and the digital conversion means for converting the imaging signal into a digital signal, and the memory of the digital signal converted by the digital conversion means are stored. (Please refer to Patent Document 2)

However, the infrared imaging device of Patent Document 2 requires not only infrared rays that can remove visible light but also infrared rays can be transmitted through the filter, and the present invention which is not necessary is at least different from this in this point.

On the other hand, the prior art proposes a night vision color image pickup device having a feature of solid-state imaging elements that capture at least two kinds of near-infrared light among two near-infrared lights of two wavelengths of red, green, and blue light. .

One of the objects of the present invention is to form a color portrait of a subject having a natural color as much as possible even in the dark.

In order to achieve the above object, an image capturing apparatus according to the present invention includes an illuminating unit, an imaging unit, and a color setting unit, wherein the illuminating unit differentiates a predetermined wavelength intensity distribution. The infrared ray is irradiated onto the subject, and the imaging unit captures the subject through the individual infrared rays reflected by the subject and forms image information indicating the respective images. Here, "R", "G" and "B" is the three primary colors, and the color setting unit sets the first image captured by the infrared light having the wavelength intensity distribution closest to the "R wavelength region" in the image indicated by the formed image information to the "R" table. The color information of the color is set to indicate the image information of the first image, and the second image captured by the infrared light having the wavelength intensity distribution of the infrared rays closest to the "R wavelength region" is close to the wavelength intensity distribution. The color information of the B color is set as the image information indicating the second image, except for the first image and the second image. In the third image captured as described above, the color information of the "G" color is set as the image information indicating the third image.

In general, there are a variety of different color spaces that can be defined, and thus a wide variety of colors. The RGB color table of the three primary colors "R", "G", and "B" using light is taken as a representative example. In the RGB color system, light having a wavelength of 700 nm is used as the primary color "R", light having a wavelength of 546.1 nm is the primary color "G", and light having a wavelength of 435.8 nm is the primary color "B" to define the three primary colors of RGB. However, it is difficult to display such a certain wavelength on most display devices other than special display devices such as laser projectors, as long as "R", "G", and "B" are regarded as having specific wavelengths. The intensity distribution can be appropriately set or defined. That is, "R", "G" and "B" are not only used to indicate a specific single wavelength or a single color, but also to indicate a specific wavelength intensity distribution, and the appearances are similar to "R", "G" and " B" The primary color of the three primary colors or the occasion of a single color.

In general, pyramidal cells in human visual cells are considered to be three types, one is a center wavelength of 564 nm, and is sensitive to a red wavelength region or a "R wavelength region" in the wavelength range of 400 nm to 680 nm, and one is a center. a wavelength of 534 nm, and a cell having sensitivity to a green wavelength region or a "G wavelength region" in the wavelength range of 400 nm to 650 nm, and a blue wavelength region or "B wavelength" having a center wavelength of about 420 nm and a wavelength range of 370 nm to 530 nm. The field has cells that are sensitive. The humans can visually correspond to the colors of "R", "G", and "B". In addition, these wavelength ranges cannot be rigorously defined due to individual differences.

The light from the object is separated into "R wavelength field", "G wavelength field" and "B wavelength field" by a color glass filter, and images of their respective wavelength regions are taken. Then, the brightness of the image obtained in the "R wavelength field" is "R", and the brightness of the image obtained in the "G wavelength field" is "G" and the brightness of the image obtained in the "B wavelength field" is "B". The three color images are superimposed and displayed in the three primary colors of light, that is, by additive color mixing, and displayed as an RGB color image. In addition, it is also possible to use CMY color representation or CMYK color representation.

As various aspects of the present invention, the color of the object, that is, the brightness of the object under visible light, or the in-plane intensity distribution of the specific physical quantity of the object, can be expressed by color brightness, but with a primary color or a single color.

In addition, the primary color or the single color may be formed by a specific wavelength or a specific wavelength intensity distribution.

In addition, according to the Spectral luminous efficiency curve of the international standard of human eye sensitivity, infrared rays, that is, wavelengths of 750 nm or more, which are invisible to the human eye, can be light or electromagnetic waves, but the wavelength sensitivity of the human eye is personally different. It is difficult to make a strict division, and the aforementioned wavelength may vary depending on the occasion. Infrared rays are generally considered to be invisible light that cannot be recognized by the human eye, but even light belonging to the infrared range can be seen as long as the intensity is very strong.

"R" or "R wavelength field" can be color or light with a center wavelength of 640 nm, "G" or "G wavelength field" can be color or light with a center wavelength of 530 nm, "B" or "B wavelength" The field may be a color or light having a center wavelength of about 435 nm. Also, the "R" or "R wavelength field" can be a color or light having a wavelength range of 625 nm to 740 nm, and the "G" or "G wavelength field" can be a color or light having a wavelength range of 500 nm to 565 nm, "B" or " The B-wavelength region can be a color or light having a wavelength in the range of 450 nm to 485 nm.

Therefore, the strict definition of "R", "G", "B", "R wavelength field", "G wavelength field" and "B wavelength field" is quite difficult and may vary depending on the occasion, and light and light For the same thing.

The so-called color setting, that is, information on which color color is to be set in advance when the image is displayed. For example, it may be set when the image information or the image signal is transmitted, or the image information or the image signal may be set in accordance with the trigger condition. Others are set by separately generating the color information or the color setting signal, or by overlapping the image information or image signal with the color information or the color setting signal, or setting the memory address of the memory. , or labeling or flag setting during signal processing.

In this case, the skin color of the person's face or hand can be reproduced, the color of the hair can be reproduced as natural black, and the luster of the metal is faithfully reproduced.

By correcting the color balance, hue, brightness, contrast, and gamma correction parameter adjustment, it is almost identical to the color image of the subject under visible light. Further, the image color can be emphasized by image processing such as differentiation of each image.

The following is a description of the principles of the present invention, each of which exhibits a unique color or spectrum. Its color or spectrum is determined by the reflectance, absorptivity or transmittance of the substance. In terms of the physical properties of electrons, the reflectance, absorptivity or transmittance is dependent on the interaction of the charge on the surface or substance of the substance with the photons. Moreover, when the fundamental absorption end or the transition interval energy level inherent in the material is in the visible light region, the reflectance, the absorptance, or the transmittance change in the visible light region, and the reflected light of the material is recognized as a color.

To synthesize a pigment that can present a substrate of a paint or pigment of a certain color, atomic or molecular replacement of the substrate to increase or decrease the absorption end or transition interval level, or by mixing impurities into the absorption end. Or the transition interval level, so that a pigment that exhibits the desired color can be synthesized.

For example, when an optical filter composed of a uniform material is used, the color of the light passing through the filter can be determined according to the transmittance of the material, and the color of the light of the reflection filter can be determined according to the reflectance of the material. In addition, if it is a transparent medium containing microparticles, not only the surface of the microparticles is scattered, but also the light that penetrates while refracting the microparticles is contained in the transmitted light and the reflected light. When the transparent medium contains microparticles, the transmittance of the medium, the reflectance of the microparticles, and the diffuse reflectance, the wavelength intensity distribution (color) of the light that passes through the filter.

The semiconductor or metal microparticles are dispersed into glass as a representative long wavelength penetrating filter. For example, if CdS is mixed in glass and heat treated, uniform size CdS fine particles are formed in the glass. According to the exciton sealing effect, the position of the absorption end of the CdS fine particles can be changed according to the size of the fine particles, and the size of the fine particles can be controlled by heat treatment conditions.

Regarding the coloration of paints or pigments, the reflectance and transmittance of the particles of the paint or pigment are determined according to the reflectance and transmittance of the medium from which the paint or pigment is purchased, and the reflectance of the material to be coated (because there is The reflection of the coating material) determines the color of the paint or pigment. A coating or pigment, although one of the covering components, can be referred to as a covering component as long as it covers possible materials.

[Experimental Example 2]

Fig. 14 is an example of the relative reflectance of materials of blue "B" green "G" and red "R", which are made of the same resin substrate. As can be seen from Fig. 14, the wavelength fields in which the reflectances of "B", "G", and "R" are large in the visible light region can be seen, and the structures mainly correspond to their respective materials, and the infrared region can also be used. See structures with their own unique reflectivity.

The shapes of the intensity distributions of the reflectances in the wavelength range from 375 nm to 1100 nm on the "B" and "G" curves were compared with each other to have a parallel moving shape relationship. This is an example of the above-mentioned "increasing or decreasing or shifting the energy level of the absorption end or the transition interval", and it can be seen that the structure of the visible light region and the structure of the infrared region move in parallel with each other.

Fig. 15 is a view showing the data before calculation of the graphs of Fig. 14 when the materials of blue "B", green "G", and red "R" are illuminated by white light, and are detected by a photodetector. The reflected light shows the relative detection rate that normalizes each signal to each maximum value.

As seen in Fig. 15, the material having the red "R" has a wavelength region with a relatively high detection rate of "IR1", and the material having a green "G" has a wavelength region with a relatively high detection rate for "IR3". The material of the blue "B" has a wavelength range in which the relative detection rate of "IR2" is high.

Therefore, it can be estimated that the material of the high-wavelength region having the relative detection rate of "IR1" is red "R", and the material of the high-wavelength region having the relative detection rate for "IR2" is blue "B", and for "IR3" The material in the high-wavelength area with a relative detection rate is green "G". That is, the reflection of the infrared ray can be estimated by the reflection of the infrared ray, which is the result of the reflection measurement of the visible region.

That is, from the infrared rays of the subject, the image of the infrared light corresponding to "IR1" is captured in the "R" color, and the image corresponding to the infrared light of "IR2" is captured in the "B" color, and the image corresponds to "IR3". The infrared image is reproduced in "G" to reproduce the color of the material under visible light.

Infrared rays corresponding to "IR1" are irradiated onto the subject, and an image obtained by photographing the light reflected from the photograph is displayed in an "R" color, and infrared rays corresponding to "IR2" are irradiated onto the subject, and The image obtained by photographing the light reflected from the self-prepared photograph is in the "B" color, and the infrared light corresponding to "IR3" is irradiated onto the subject, and the image obtained by reflecting the light reflected from the photograph is "G". The color of the material can reproduce the color of the material under visible light.

[Experimental Example 3]

Figure 16 (a) is an image taken on a black paper using a symbol and a character drawn by a painting member of a green, red, and blue covering component as a subject, mainly under a fluorescent light emitting visible light. 16(b) shows that the image capturing apparatus of the present invention captures a color image of the same subject under almost the same conditions as those of Figs. 12(b-1) and 13(b).

Comparing Fig. 16(a) with Fig. 16(b), it can be seen that the color of Fig. 16(b) has a true reproduction of the color of Fig. 16(a), and the image capturing apparatus using the present invention can be known. The object in the darkness captured by the image photographing method can surely reproduce the image of the subject photographed with visible light.

Since the present invention can photograph and display and store a color still image or a color animation of a subject in the dark, it can also be used as a night vision camera or the like for monitoring or maintenance.
