Description

  The present invention relates to a dermoscope technique used for examining skin diseases.

  In recent years, an increase in skin diseases such as melanoma (malignant melanoma) has become a problem due to aging and ozone layer destruction. Even when observing with the naked eye or a normal loupe, it is difficult to distinguish melanoma from benign pigment cell nevus and blood beans, and it is difficult to detect and treat melanoma early.

  Most of the light that goes to the skin is reflected by the skin surface or absorbed by the skin. For this reason, when using the naked eye or a normal loupe, most of the information received from the eyes is information about the skin surface, and sufficient information about the inside of the skin could not be obtained. In other words, the difficulty in distinguishing between melanoma and benign pigment cell nevus is that melanoma and benign pigment cell nevus are different in pigment distribution and color within the skin using the naked eye or a normal loupe. Also, it was caused by insufficient observation of information inside the skin.

  Therefore, a dermoscope capable of observing the pigment distribution and hue inside the skin by utilizing the fact that the skin is partially translucent is used for such diagnosis. The dermoscope irradiates the target part with light emitting diodes, etc., reduces the reflected light from the skin surface covering the inside of the skin, and expands the target part by 10 to 30 times to observe it. Inflammation, color, pigmentation, hair follicles and blood vessels inside the skin can be visualized invasively.

  As a method for reducing the reflected light from the skin surface, a method using an echo gel or a polarizing filter is known. In the case of using the echo gel, by applying the echo gel to the skin surface, the influence of the irregularities of the stratum corneum on the skin surface is eliminated, and the irregular reflection of light is suppressed.

  On the other hand, when a polarizing filter is used, the first polarizing filter that linearly polarizes light from the light source toward the skin, and the first polarizing filter that is positioned on the path of reflected light from the skin to the lens, In comparison, the second polarizing filter whose polarization direction is shifted by 90 ° is used to reduce the reflected light from the stratum corneum on the skin surface. The light from the light source whose vibration direction is adjusted to one plane by the first polarizing filter changes the vibration direction slightly every time it collides with the diffuse reflector contained in the skin, and is reflected by the skin surface. The direction of vibration hardly changes. Therefore, by using the two polarizing filters, it is possible to reduce the influence of the reflected light due to the keratin on the skin surface and obtain a cross-polarized image visualizing the inside of the skin. For example, a dermatologist determines the malignancy of a lesioned part by observing the randomness of the color change in the marginal part of the cross-polarized image.

  In the dermatology area, there are many opportunities to take photographs according to the medical treatment contents. For example, if you are an atopic patient, you will usually take a photo every time you visit to see changes in symptoms, or if you are worried about the nevus, you can observe the target site X by observing with a dermoscopy lens. After identification, in order to determine whether it is benign pigmented nevus or malignant melanoma (malignant melanoma), normal photo imaging or dermoscopy imaging of target site X is performed, and which patient's photo is specified In order to do this, multiple devices had to be used to image the chart.

  Furthermore, it is desired to observe or image both the skin surface and the inside of the skin in order to compare or overlay the image of the skin surface with the image inside the skin, and the state where the skin surface can be observed or imaged. And a dermoscope capable of switching to a state where the inside of the skin can be observed or imaged and comparing them can be desired.

  For example, Patent Document 1 discloses a diode 58, an upper polarizing filter 50 and a lower polarizing filter 52 that polarize light from the diode 58, and an optical lens 14 that can enlarge and visually recognize a target portion via the observation polarizing filter 24. , A dermoscope is disclosed. Since the polarization axis direction of the upper polarization filter 50 is shifted by 90 ° with respect to the polarization axis direction of the observation polarization filter 24, the upper polarization filter 50 uses the light that has passed through the upper polarization filter 50, It is possible to provide a visualized cross-polarized image. On the other hand, when the light passing through the lower polarizing filter 52 is used in the lower polarizing filter 52, the polarization axis direction of the lower polarizing filter 52 is parallel to the polarizing axis direction of the observation polarizing filter 24. It is possible to provide a parallel polarization image in which the topography and properties of the surface are emphasized.

  The upper polarizing filter 50 and the lower polarizing filter 52 are respectively provided with openings at positions corresponding to predetermined diodes 58. By switching the light emitting diodes 58 with the switches 16 and 18, the cross-polarized image and the parallel polarized light are switched. It is configured to be able to switch between images. Further, it is disclosed that an imaging device such as a camera may be attached to the dermoscope.

US Patent No. 7,006,223

  However, Patent Document 1 does not disclose any specific configuration regarding a dermoscope with an imaging device.

Accordingly, an object of the present invention is to provide an imaging device for dermoscopy, a control method thereof, and a program for easily storing identification information for identifying a patient, normal photographic imaging such as a skin surface, and dermoscopy imaging capable of imaging the inside of the skin.

When there are a plurality of imaging unit light sources 104, the plurality of imaging unit light sources 104 may include light sources having the same wavelength or may include light sources having different wavelengths. For example, since ultraviolet rays or blue light is easily absorbed by the pigmentation part, the pigmentation part can be visualized suitably. Similarly, since green light is easily absorbed by the blood vessel, the blood vessel can be suitably visualized. White light can obtain anatomical information used in the diagnosis of skin diseases, or can better visualize the skin surface.

  Therefore, the plurality of imaging unit light sources 104 are configured such that when one wavelength light source is turned on, the other wavelength light source is turned off, or when the other wavelength light source is turned on. You may comprise so that the light source of a wavelength may turn off. Thereby, information inside the skin can be obtained more suitably, and by comparing or superimposing these images, it is possible to facilitate examination, diagnosis and treatment of the target portion. The imaging unit light source 104 may further include a focus lens for concentrating light. The imaging unit light source 104 is fixed to a circuit board (not shown), and is electrically connected to the wiring of the circuit board (not shown) using solder or the like.

For example, the image data generation unit 125 appropriately adjusts the gain for each RGB color component with respect to the analog image pickup signal, and then samples and holds it by a sample hold circuit (not shown), and an A / D converter (not shown). The digital data is converted into digital data, and color processing including pixel interpolation processing and γ correction processing is performed in a color process circuit (not shown), and then image data including luminance signals and color difference signals of digital values is generated. This image data is transferred to the storage unit 140 via a DMA controller (not shown) or the like.

(Storage unit 140)

As the plurality of image data, for example, with a proper exposure as a reference value, the shutter speed, the signal amplification factor, the aperture value, and the like are changed so that the underexposure and overexposure are performed with respect to the reference value, and the focal length is changed. It includes image data of the image data D d and already past dermoscopy images that exist in the plurality of dermoscopy images of substantially equal composition taken by the fixed state.

  According to this, since the dermoscopy converted image can clarify and reveal the image of the target part X more than the dermoscopy image, the target part X can be more accurately inspected and diagnosed.

  For example, the image conversion unit 160 includes a composite image generation unit 161, an image acquisition unit 162, a component separation unit 163, a first generation unit 164a, an enhancement amount acquisition unit 165, a pixel value correction unit 166, and a correction amount.

Note that each unit of the image conversion unit 160 includes, for example, a predetermined logic circuit, but the configuration is an example and the present invention is not limited to this.

  The composite image generation unit 161 generates image data of a composite image obtained by combining the plurality of image data. Next, the image acquisition unit 162 acquires the image data of the composite image generated by the composite image generation unit 161 from the storage unit 140, and the component separation unit 163 uses the image data of the composite image as a luminance component or a luminance component. Separated into image components including color difference components. Next, the first generation unit 164a sequentially repeats the smoothing process and the resolution reduction process on the luminance component of the composite image to generate an n-stage Gaussian pyramid of the luminance component. Subsequently, the first generation unit 164a performs smoothing for each stage of the n-stage Gaussian pyramid of the luminance component to generate an n-stage smoothed Gaussian pyramid. Next, the enhancement amount acquisition unit 165 returns each of the n-stage smoothed Gaussian pyramids of the luminance component generated by the first generation unit 164a to the original size, and generates an n-stage resized smoothed Gaussian pyramid.

  Subsequently, the enhancement amount acquisition unit 165 sets the luminance component for each pixel of the composite image and the luminance component for each pixel of the n-stage resized smoothed Gaussian pyramid of the luminance component in the range of “0” to “1”. Each value is normalized, and the enhancement amount at each stage of the luminance component is acquired based on the difference between them. Next, the pixel value correction unit 166 corrects the luminance component for each resolution based on the enhancement amount for each of a plurality of stages of the luminance component acquired by the enhancement amount acquisition unit 165, and enhances n stages. A luminance component is generated. Next, the high frequency component acquisition unit 168 generates an n-stage × n-group Laplacian pyramid with each of the n-stage enhanced luminance components generated by the pixel value correction section 166 as a group. Next, the data configuration control unit 169 selects a hierarchical image (luminance component Y) one by one from each group of n-stage × n-group Laplacian pyramids acquired by the high-frequency component acquisition unit 168 and n-stage Gaussian. A replica of the nth hierarchical image of the pyramid is incorporated into the highest level to generate an nth final Laplacian pyramid.

Subsequently, the data configuration control unit 169 reconstructs by performing “enlargement”, “addition”, and the like in order from the hierarchical image of the upper level of the final n-stage Laplacian pyramid, and generates a luminance component. Next, the second generation unit 164b may amplify the value of the color difference component to a degree substantially equal to the enhancement amount of the luminance component acquired by the enhancement amount acquisition unit 165, and generate the color difference component. Subsequently, the data synthesis unit 164c uses the luminance component, or by combining the luminance component and chrominance components, and generates an dermoscopy converted image data D t1. Then, the image conversion unit 160, encodes the dermoscopy converted image data D t1 in a predetermined compression format, by outputting to the storage unit 140 stores the dermoscopy converted image data D t1.

  In the above embodiment, an example is shown in which the component separation unit 163 separates each of the luminance component and the color difference component. However, the present invention is not limited to this example. It can be changed.
