Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.

Fig. 1 is a flowchart of a method for adjusting an image of a medical electronic film according to an embodiment of the present invention. Referring to fig. 1, a method for adjusting an image of a medical electronic film includes:

step 101: and acquiring an image of the film to be adjusted.

After the medical device captures an image of the patient, the image is taken as the film image to be adjusted. Here, the adjusting device of the present application can acquire the film image to be adjusted from the medical device.

Step 102: and dispersing the film image to be regulated into a preset regulating graph coordinate system.

After obtaining the film image to be adjusted, in order to adjust the color lookup table in the film image to be adjusted, the film image to be adjusted is mapped and dispersed into a preset adjustment chart coordinate system of 600 pixels by 600 pixels. The position information of the film image to be regulated can be accurately obtained by utilizing the preset regulating coordinate system, and coordinates are allocated to each pixel point in the film image to be regulated, so that the black and white color concentration of the film image to be regulated can be conveniently and accurately controlled. It should be noted that the size of the preset map coordinate system is not limited to the size set in the above embodiment, and may be determined according to practical situations.

Step 103: and receiving operation data of a user, and determining a tone map key point selected by the user on a preset reference curve in the preset tone map coordinate system according to the operation data.

When the film image to be adjusted is adjusted, the adjusting device displays an image color lookup table adjusting interface to a user. When the film image to be adjusted is dispersed into the preset tone map coordinate system, the current interface displays the preset tone map coordinate system mapped with the film image to be adjusted and the film image to be adjusted to the user. At this time, a preset reference curve is set in the preset map setting coordinate system, and then a user can autonomously select a map setting key point on the preset reference curve according to the actual image condition of the film image to be adjusted. And when the user selects the key point of the picture adjustment, the key point can be selected according to the display condition of the film image to be adjusted displayed on the current interface. For example, the image display at the position A in the film image to be adjusted on the preset reference curve is blurred, the black and white level is not clear, and at the moment, the user sets the position A on the preset reference curve as a key point of the tone map.

The number of key points of the tone map is not fixed, and can be multiple or one, and the specific number is selected according to the requirements of users and the definition of the film images to be regulated. The definition of the image can be improved by changing the number of key points of the tone map.

Step 104: and moving the position of the key point of the picture adjustment, and carrying out black and white concentration adjustment on the film image to be adjusted by combining a Bezier curve algorithm until a target electronic film image meeting the requirement of a user is obtained.

When the key point of the map is selected, the user controls the position of the key point of the map on the current interactive interface, in the process of moving the position of the key point of the map, the display definition of the image at the position of the key point of the map can be changed, the black-white level can be changed, and the user can set the key point of the map at the position with clear black-white level. Meanwhile, in the process of moving the position of the key point of the tone map, the image near the position of the key point of the tone map is properly adjusted by combining with a Bezier curve algorithm. The Bezier curve algorithm can adjust the black and white concentration of the image near the key point of the map while adjusting the black and white concentration at the position of the key point of the map, and the color difference between the key point image and the surrounding image is abrupt.

In the above embodiment, the film image to be adjusted is mapped and combined with the preset map coordinate system, the preset reference curve is set in the preset map coordinate system, the user selects the map key point on the preset reference curve according to the color display condition of the film image to be adjusted, and then the user adjusts the black and white concentration of the image at the key point position by moving the position of the map key point. Meanwhile, a Bezier curve algorithm is combined in the adjusting process, so that a smooth effect is achieved through preset reference curves of a plurality of key points, and further, the optimal effects of distinct layers and no fault of color are achieved through film image imaging.

In order to describe the electronic film image adjusting method in more detail, another specific embodiment is provided for description based on the above embodiment, which is specifically described below.

Fig. 2 is a flowchart of a method for adjusting an image of a medical electronic film according to another embodiment of the present invention.

Referring to fig. 2, a method for adjusting an image of a medical electronic film includes:

step 201: and acquiring an image of the film to be adjusted.

Step 202: and judging whether the film image to be regulated is an 8-bit map or not.

In the present application, in performing electronic film image adjustment, the image used needs to be an 8-bit image. Therefore, after receiving the film image to be adjusted, a determination needs to be made as to whether the film image to be adjusted is 8-bit.

Step 203: and if the film image to be regulated is not 8 bitmaps, converting the film image to be regulated into the film image to be regulated in the form of 8 bitmaps.

When the acquired film image to be adjusted is not an 8-bit image, the film image to be adjusted needs to be converted into the 8-bit image, and the following operation can be performed on the basis of the 8-bit image.

It should be noted that, in the present application, the case that the film image to be adjusted must be an 8-bit image is not fixed, or the pixels of the film image to be adjusted may not be set, or other criteria may be set, which may be specific to the actual application scenario.

Step 204: and converting the film image to be regulated into a 24-gray-scale image.

In the application, a basic 24 gray-scale map is used when performing image color lookup table adjustment. I.e. the film image to be adjusted is divided into images with 24 square areas. The 24 gray-scale images can be used for accurately dividing the areas of the film images to be adjusted, so that the areas can accurately correspond to a preset tone-scale coordinate system.

Step 205: and correspondingly dispersing the 24 gray-scale images into the preset tone map coordinate system.

Step 206: and receiving operation data of a user, and determining a tone map key point selected by the user on a preset reference curve in the preset tone map coordinate system according to the operation data.

Before the user selects the key point of the map, a preset reference curve needs to be generated in advance. The application has two modes of generating the preset reference curve, one is that the diagram regulating software system can directly display the preset curve library to the user, a plurality of curves are stored in the preset curve library, and the user can select the required curve in the preset curve library as the preset reference curve according to the actual needs. The other is that the user can select a certain position on the interactive interface in a self-defined way as a preset reference curve. The specific generation mode of the preset reference curve is not fixed and depends on the actual requirements of users and the actual conditions of the film images to be regulated.

One end of the preset reference curve is a lower left corner in the preset coordinate system, and the other end of the preset reference curve is an upper right corner of the preset coordinate system. I.e. a diagonal in a preset coordinate system, which is a diagonal connecting the lower left corner and the upper right corner. The color of the preset reference curve connected with the lower left corner of the preset coordinate system is set to be black, and the color concentration is gradually reduced along the curve direction until the color of the curve connected with the upper right corner of the preset coordinate system is set to be white.

Step 207: and performing up-and-down movement operation on the picture adjustment key points on the preset reference curve, and performing black-and-white concentration adjustment on the film images to be adjusted at the positions corresponding to the picture adjustment key points.

After the key point of the map is selected, the key point of the map is moved up and down, and then the black and white density of the image at the position of the key point can be adjusted. For example, moving downward will darken the black color at that location and moving upward will darken the white color at that location. The black-and-white level in the image can be adjusted by adjusting the black-and-white concentration, so that the image definition can be changed.

Step 208: and (3) carrying out black and white concentration adjustment on the film image to be adjusted in the setting range of the key points of the tone map by utilizing a Bezier curve algorithm, and displaying an operation interface for adjusting the black and white concentration of the film image to be adjusted in real time.

In the method, the black and white concentration of the electronic film image can be adjusted by moving the position of the key point of the tone map so that the image imaging achieves the best effect of distinct gradation and no fault of color. And in the process of moving the key points of the picture, the change condition of the black-white concentration in the moving process is displayed in real time, so that the function of timely feeding back the regulating effect is achieved. Therefore, the adjusting time is shortened, and the waste of film consumable materials is reduced.
