color Mapping  Image processing method through

The image processing method using color mapping according to a preferred embodiment of the present invention is a method of image processing in which the image photographing apparatus 100 irradiates a body permeability radiation line and photographs an image including physical quantity information formed as a result of irradiation of the radiation line, (A) generating a color mapping layer by color mapping the included physical quantity information according to predetermined color mapping table information and providing the image and a color mapping layer; And outputting the image to the display, wherein the process of calculating the physical quantity information for the image is performed according to the stored color mapping table information and the information of the color mapping layer provided (b).

That is, in the image processing method using color mapping according to the present invention, the image capturing apparatus 100 for radiating any body permeability radiation such as X-ray, ultrasound, And a color mapping layer in which a physical quantity information included in the photographed image is color-mapped in accordance with preset color mapping table information, And providing the image and the color mapping layer (step (a)).

Then, the image output terminal 200 receives the provided image and color mapping layer from the image capturing apparatus 100, and outputs the image to the display. At this time, the physical quantity information calculation process for the image input to the image output terminal 200, that is, the physical quantity information extraction for a specific point in the image, or the physical quantity information about the difference in the physical quantity information values between two points selected on the image The calculating process includes a step (b) of performing the calculation according to the stored color mapping table information and the information of the color mapping layer provided.

More specifically, in the step (a), the image capturing apparatus 100 irradiates a radiation and captures an image including the physical quantity information formed as a result of the inspection, wherein the physical quantity information included in the image Create and provide a color mapping layer with color mapping of information.

At this time, the color mapping table information is preliminarily set and stored according to the characteristics of the radiation, that is, when the radiation is X-ray, ultrasonic wave, radiation, or the like, A color mapping layer is created according to the color mapping table information in which the physical quantity information included in the image is stored, and the color mapping layer is provided to the image output terminal 200 together with the image.

At this time, the data of the provided image may be provided with the header information of the physical quantity information included in the photographed image being excluded.

That is, in the image photographing device, only the image data of the photographed image itself is provided to the image output terminal 200 without adding header information about the photographed image, and the physical quantity information included in the image provides the color mapping layer To be provided.

The color mapping layer may be generated to have coordinates corresponding to coordinates on the photographed image screen.

In step (b), the image output terminal 200 outputs only the image of the provided image and the color mapping layer to the display, and outputs physical quantity information of the selected point on the image displayed on the display, The physical quantity information calculation process for the difference value of the physical quantity information and the like is performed in accordance with the physical quantity information about the point on the color mapping layer corresponding to the corresponding point.

At this time, the color mapping table information is stored in the image output terminal 200.

That is, the image output terminal outputs only the image provided to the display, and the physical quantity information calculation process for the selected point on the image input through the display is performed in accordance with the stored color mapping table information and the information of the color mapping layer Only the image excluding the physical quantity information is excluded from the image data including the enormous amount of data by including the existing header information, and the selected point on the image output to the display, the physical quantity The information calculation processing is performed according to the color mapping table information and the color on the color mapping layer at a point corresponding to the selected point.

This avoids the problems such as various buffering occurring in the physical quantity calculation processing by the image data itself, which is made up of a huge amount of data including the header information, and delays occurring in calculating the result value.

In this case, the color mapping table information in the step (a) is preset table information so that color bands of different colors are allocated to the physical quantity information for each predetermined amount of change, and the color mapping layer sets the color mapping table information according to the color mapping table information And a color band having a predetermined width is formed along the predetermined reference direction on the image.

The generation of the color mapping layer is performed according to the color mapping table information, and is set such that color bands of different colors are allocated to the physical quantity information for each predetermined variation amount.

In addition, the color mapping layer is formed so as to form a color band having a predetermined width along a predetermined reference direction on the image.

At this time, the reference direction will be set in a direction suitable for measuring the change direction of the physical quantity information or the change quantity of the specific physical quantity information as a result of the survey of the radiation.

The calculating process of the physical quantity information for the image in the step (b) may include calculating the physical quantity information value of a specific point on the image outputted to the display, that is, the physical quantity information value of the specific pixel, A difference value to a value, and the like, and calculation processing for information calculated from an X-ray imaging, an ultrasound imaging, or a bone density imaging image.

The display of the video output terminal in the present invention is preferably configured by a touch screen method.

That is, when the image and the color mapping layer are received and only the image is output to the display, when a specific point, i.e., a physical quantity information value calculation signal at a specific pixel is input by the user, The physical quantity value of the previously stored color mapping table information corresponding to the color of the corresponding point is calculated as the physical quantity information value for the specific pixel.

In other words, the image processing method using color mapping according to the present invention can be performed by using only the image file excluding the provided header information, the color mapping layer and the pre-stored color mapping table information, The physical quantity information calculation processing for each point included in the image becomes possible.

In addition, header information including enormous amount of data causing problems such as computation delay, buffering and the like is excluded from the image and simply replaced with a color mapping layer, thereby improving the compatibility between the video output terminal and the image capturing apparatus, So that the process of calculating the physical quantity information can be performed quickly.

The step (b) may further include a step of calculating a difference value of physical quantity information between two adjacent pixels among the pixels constituting the image.

The calculation of the difference value of the physical quantity information between the adjacent two pixels among the pixels constituting the display on which the image is output, that is, the inter-pixel physical quantity difference value, may be performed at two spaced apart points, The difference between the two spaced pixels is multiplied by the difference value of the physical quantity information between the adjacent two pixels to calculate the difference value of the physical quantity between the two pixels.

At this time, since each pixel constituting the display of the video output terminal will have position coordinates on a display on the display, as in a general display, since the distance between the two spaced pixels is equal to the distance between the pixels Position coordinates can be calculated by applying Pythagorean theorem and the like.

Hereinafter, the difference value calculation method for the physical quantity information between the adjacent two pixels will be described in detail.

The difference value calculation method for the physical quantity information between the adjacent two pixels may be calculated based on any one of the pixels constituting the image output to the display or may be calculated using two or more arbitrary or selected pixels .

First, a method of calculating a difference value between the adjacent two pixels based on any one of the pixels constituting the image output to the display will be described.

First, a first reference point, which is a point on the color mapping layer, corresponding to one of pixels constituting the image is set.

The first reference point may be a first reference point, which is a first color band, which is one of the color bands of the color mapping layer, and a second color band that is in contact with a boundary line of the color band adjacent to the first reference point, A first 1-2 sub reference point which is a pixel tangent to a 1-1 second sub reference point or a boundary line between adjacent color bands on the other side is set.

In this case, the reference direction may be a direction orthogonal to a direction in which color bands of the color mapping layer are formed.

That is, the first reference point is contacted with the first 1-1 second reference point, which is a point contacting the boundary line between the first color band and the adjacent color band along the reference direction, or the boundary line between the first color band and the adjacent color band 1 < / RTI > sub reference point.

In this case, it is preferable that the 1-1 second sub-reference point to the 1-2 sub-reference point are included in the first color band and are set so as to be in contact with the boundary line with the adjacent color band.

The first reference point is connected to a second color band, which is a color band other than the first color band, of the color band of the color mapping layer and a second color band that is adjacent to a boundary line between the adjacent color band 2 < 2 > sub reference point, which is a point tangent to the boundary line with the adjacent color band on the other side.

In this case, it is also preferable that the 2 < rd > -1 sub reference point to the 2 < 2 > sub reference points are included in the second color band and are in contact with the boundary line between adjacent color bands.

Finally, a difference value between the physical quantity information value allocated to the first color band and the physical quantity information value allocated to the second color band is set to the shortest distance between the first sub-reference point and the second- A difference value between the adjacent two pixels is calculated by calculating a value divided by the number of pixels on the image included in the shortest distance between the first and second sub reference points.

Next, a method for calculating a difference value between physical quantities of information between two adjacent pixels will be described using a method of calculating an output image on the display using any or two selected pixels.

Hereinafter, for convenience of explanation, the image photographing apparatus will be described as an example of an ultrasound image photographing apparatus (refer to FIG. 13 to FIG. 14).

That is, the image is an ultrasound image, the physical quantity information is depth information, and the color mapping table information and the color mapping layer are related to the adapter information.

First, a first method (refer to FIG. 14 (b)) is used as a method for calculating a difference value between the adjacent two pixels by using arbitrary or selected two pixels constituting an image outputted to the display, And a second method (see Fig. 14 (c)) will be described.

A first color (P1) on the color mapping layer corresponding to each of the ultrasound image first pixel (P1) having a small Adams value and a second pixel (P2) having a large Adverse value among the two pixels selected on the display on which the ultrasound image is displayed, Coordinates corresponding to the first pixel P1a included in the band and the second pixel P2a included in the second color band are extracted

Then, on the color mapping layer in which the ultrasound image first pixel P1 and the ultrasound image second pixel P2 correspond to the selected ultrasound image, the first pixel P1a is divided into a first color P1, And corrects the position so that the second pixel P2a is in contact with the boundary line between the color band including itself and the color band adjacent to the lower side.

At this time, it is preferable that the position P1a is included in the color band including itself and that the position P2a is included in the color band adjacent to the lower side.

An absolute value of an adverse value which is a value obtained by subtracting a second Adams value for a color band including the position-corrected second pixel (P2b) from a first Adasc value for a color band including the position-corrected first pixel (P1b) Corrected value of the first pixel P1b by the absolute value of the vertical distance which is a value obtained by subtracting the vertical coordinate value of the position-compensated second pixel P2b from the vertical coordinate value of the position-corrected first pixel P1b, In this case, the difference value (CPP, Cm Per Pixcel, in this case, not only the unit of cm but also other various length units can be used) is calculated as the distance (or the distance) between adjacent pixels.

At this time, the distance between the coordinates of the ultrasound image first pixel P1 and the ultrasound image second pixel P2, or the distance between the first pixel P1a and the second pixel P2a, And calculates a difference value, that is, a distance value, of the actual ADX information for the ultrasound image first pixel and the ultrasound image second pixel.

In this case, if the color layer first pixel P1a touches the boundary line between the color band adjacent to the upper side in the color band including the position correction itself, the corrected color layer first pixel P1b is positioned at the position When the color layer second pixel P2a is in contact with the boundary line of the color band adjacent to the upper side in the color band including itself before the position correction, And the corrected color layer second pixel P2b is regarded as the same as the color layer second pixel P2a before the position correction to calculate the inter pixel distance value.

Next, the second method will be described (see (c) of FIG. 00).

A second ultrasound image display unit for displaying ultrasound images corresponding to the first and second ultrasound images on the display unit, The corresponding coordinates for the first pixel P1a and the second pixel P2a on the color mapping layer are extracted.

On the color mapping layer corresponding to the ultrasound image in which the ultrasound image first pixel P1 and the ultrasound image second pixel P2 correspond to the selected ultrasound image, the first pixel P1a is contacted to the boundary between the first pixel P1a and the adjacent color band And corrects the position so that the second pixel P2a is in contact with the boundary line between the color band including itself and the color band adjacent to the lower side.

At this time, it is preferable that the positions P1a and P2a are corrected so as to be included in the color band included therein.

The position-corrected color layer second pixel P2b is calculated by subtracting a second Adams value for a color band including the position-corrected color layer second pixel P2b from a first Adams value for a color band including the positionally corrected color layer first pixel P1b A value obtained by dividing an absolute value of the difference in the depth difference by an absolute value of a vertical distance which is a value obtained by subtracting the vertical coordinate value of the position-corrected color layer second pixel (P2b) from the vertical coordinate value of the first color- (CPP, Cm Per Pixcel, in this case, it is natural that various other length units can be used as well as the distance between the adjacent pixels) .
