Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to an image processing device with a dual image interface. Background Art

[0002] A medical endoscope is a medical device used to examine the internal organs of the human body. It has a slender insertion tube with a light source and a camera at one end. It can be inserted into the body through natural orifices (such as the respiratory tract, urethra) or through a small incision to observe the conditions of the esophagus, stomach, intestines, respiratory tract, joint cavity, etc. The other end of the tube is connected to an endoscope image processing host with a display, so that the image captured by the camera is transmitted back to the external screen so that the doctor can see the patient's internal conditions. The endoscope camera can be high-definition, and some are even equipped with a magnification function or special filters to further improve the accuracy of the diagnosis.

[0003] However, the endoscope image processing hosts currently on the market generally have only one endoscope interface, which means that each type of endoscope requires a separate image processing host to support it. Therefore, if multiple endoscopes are required for examination, doctors may need to operate multiple devices, which not only increases the complexity of the operation, but also reduces work efficiency. Summary of the invention

[0028] When the first image interface is not connected to an image acquisition device and the image acquisition task of the first image interface is turned on, controlling to turn off the image acquisition task of the first image interface.

The execution order and execution logic between each step should be understood and inferred with reference to the contents described in the embodiment.

[0054] Further explanation is given below based on the accompanying drawings.

[0055] Specific reference Figure 1 and Figure 2 , Figure 1The figure shows a schematic diagram of the structure of an optional embodiment of the image processing device 100 with dual image interfaces of the present application. Figure 2 The figure shows a flow chart of an optional embodiment of a method executed by the image processing device 100 with dual image interfaces of the present application.

[0056] The image processing device 100 with dual image interfaces includes:

[0057] A first image interface 110, a second image interface 120, a controller 130 and a display 140;

[0058] The first image interface 110 and the second image interface 120 are both connected to the controller 130 and both support hot swapping;

[0059] The controller 130 is connected to the display 140, wherein the controller 130 is used to perform the following steps:

[0060] S101, determining a device connection state of the first image interface 110;

[0061] S102, when the first image interface 110 is connected to an image acquisition device, controlling acquisition of image data through the first image interface 110;

[0062] S103, when the first image interface 110 is not connected to an image acquisition device, controlling acquisition of image data through the second image interface 120;

[0063] S104: After processing the image data, send it to the display 140 for display.

[0064] In this embodiment, the first image interface 110 and the second image interface 120 can be used to connect image acquisition devices of different models and both support hot plugging. The parameters such as image resolution and frame rate of image acquisition devices of different models may be different.

[0065] The controller 130 may be a micro control unit (MCU), which is provided with peripheral circuits and a computer-readable storage medium, wherein the storage medium stores a program, which, when executed, can complete operations such as creation and closing of image acquisition tasks, processing of image data, and initialization of image acquisition devices.

[0066] For example, Figure 1As shown, after the first image interface 110 and the second image interface 120 are connected to the image acquisition device, the MJPG image data can be uploaded to the controller 130, and the controller 130 can convert the MJPG image data into video stream data in YUV422 format and send it to the display 140 for display. The controller 130 can also send control signals to the first image interface 110 and the second image interface 120 to implement operations such as the creation and closing of the above-mentioned image acquisition tasks and the initialization of the image acquisition device.

[0067] In addition, it should be noted that, since the image processing device in the present application is an image processing device with dual image interfaces, considering the situation where two interfaces are used alternately, there are four connection states, namely, the combination of whether the first image interface 110 is connected or not and whether the second image interface 120 is connected or not. Therefore, this requires that the image processing device 100 with dual image interfaces can automatically and accurately identify the four connection states, automatically initialize device parameters, and flexibly complete the configuration of image setting parameters for different connection states, and automatically switch to display images collected by different image acquisition devices.

[0068] Based on this, when the program stored in the storage medium of the controller 130 is executed, the method flow of steps S101-S104 described above can also be executed. In this method flow, the controller 130 sets the priority of the first image interface 110 to be higher than that of the second image interface 120, and then when it is determined that the first image interface 110 is connected to an image acquisition device, the controller 130 controls the acquisition of image data through the first image interface 110, and when the first image interface 110 is not connected to an image acquisition device, the controller controls the acquisition of image data through the second image interface 120. In this way, when the interface with a higher priority is not connected to an image acquisition device, the software automatically switches to the image interface with a lower priority; when the image interface with a higher priority is connected to an image acquisition device, the software automatically switches to the interface with a higher priority, thereby avoiding the situation where image output conflicts occur when two image interfaces are connected to image acquisition devices at the same time.

[0069] The image processing device 100 with dual image interfaces according to the embodiment of the present application has at least the following beneficial effects:

[0070] The image processing device 100 with dual image interfaces of the present application has a first image interface 110 and a second image interface 120 that support hot plugging, as well as a controller 130 and a display 140, and the controller 130 can automatically switch between the first image interface 110 and the second image interface 120. Therefore, the image processing device 100 with dual image interfaces can integrate the image processing and display functions of two image acquisition devices. This design allows the operator to observe the images of two image acquisition devices on one image processing device, effectively reducing the number of devices required by the user to operate different image acquisition devices, simplifying the operation process, and thus improving work efficiency.

[0071] In some possible implementations, Figure 1 Based on the embodiment shown, specific reference is made to Figure 3 , Figure 3 1 is a schematic diagram of another embodiment of an image processing device 100 with dual image interfaces according to the present application. The image processing device further includes a first ISP 150 and a second ISP 160;

[0072] The first image interface 110 and the second image interface 120 are connected to the first ISP 150 and the second ISP 160 respectively;

[0073] The first ISP 150 and the second ISP 160 are connected to the controller 130 via the same data transmission interface.

[0074] In this embodiment, the first image interface 110 and the second image interface 120 are respectively connected to the controller 130 through the first ISP 150 and the second ISP 160, and the first ISP 150 and the second ISP 160 are further connected to the controller 130 through the same data transmission interface. In this way, after the original image data collected by the image acquisition device is transmitted to the ISP via the image interface, the ISP can extract the original image data and optimize the image information, such as performing denoising, automatic exposure control, color correction, and image compression, so as to improve the image quality finally outputted by the controller 130 to the display 140.

[0075] In addition, refer to Figure 3 For example, after processing the raw image data, the first ISP 150 and the second ISP 160 can output MJPG image data. The first ISP 150 and the second ISP 160 can receive control instructions sent by the controller 130 through the data transmission interface to implement operations such as creation and closing of the image acquisition task of the controller 130 and initialization of the image acquisition device. The data transmission interface can be a USB interface.

[0076] In some possible implementations, the first image interface 110 and the second image interface 120 are used to connect a first endoscope and a second endoscope, respectively.

[0077] In this embodiment, the aforementioned image acquisition device can be an endoscope, and the first endoscope and the second endoscope respectively connected to the first image interface 110 and the second image interface 120 can be of different models with different camera modules and different resolutions and frame rates to meet different image acquisition requirements.

[0078] In some possible implementations, the first image interface 110 is connected to a hardware interface of the controller 130, and step S101, determining the priority of the first image interface 110 and the second image interface 120, may specifically include:

[0079] Reading a connection status signal of the first image interface 110 through a hardware interface;

[0080] The device connection status of the first image interface 110 is determined according to the connection status signal.

[0081] In this embodiment, the hardware interface may specifically be a detection pin on the controller 130, the first image interface 110 is electrically connected to the detection pin, and the controller 130 may determine the connection status of the current image acquisition device of the first image interface 110 by reading the connection status signal of the detection pin. In this embodiment, the switching of the two image interfaces can be realized through only one hardware interface, which reduces the hardware complexity and simplifies the control logic.

[0082] In some possible implementations, the hardware interface may be a GPIO interface, and the step of determining the device connection status of the first image interface 110 according to the connection status signal may specifically include:

[0083] When the connection status signal is at a high level, it is determined that the first image interface 110 is connected to an image acquisition device; otherwise, it is determined that the first image interface 110 is not connected to an image acquisition device.

[0084] In this embodiment, the above-mentioned hardware interface can be specifically a GPIO interface, which is a common interface type in integrated circuits and can be a pin on the controller 130. The GPIO interface is configured in an input mode, and can read a connection status signal of an image acquisition device connected to the first image interface 110, and transmit these status information signals to the controller 130. Specifically, when the connection status signal is read as a high-level signal, it is determined that the first image interface 110 is connected to an image acquisition device, and when the connection status signal is read as a low-level signal, it is determined that the first image interface 110 is not connected to an image acquisition device.

[0085] In some possible implementations, the controller 130 may also be configured to perform the following steps:

[0086] Determine the activation status of the image acquisition tasks of the first image interface 110 and the second image interface 120;

[0087] When the first image interface 110 is connected to an image acquisition device, before the step of controlling the acquisition of image data through the first image interface 110, the controller 130 may also be used to perform the following steps:

[0088] When the first image interface 110 is connected to an image acquisition device and the image acquisition task of the second image interface 120 is turned on, controlling to turn off the image acquisition task of the second image interface 120;

[0089] When the first image interface 110 is not connected to an image acquisition device, before the step of controlling the acquisition of image data through the second image interface 120, the controller 130 may also be used to perform the following steps:

[0090] When the first image interface 110 is not connected to an image acquisition device and the image acquisition task of the first image interface 110 is turned on, the image acquisition task of the first image interface 110 is controlled to be turned off.

[0091] In this embodiment, before the controller 130 acquires image data through the image interface, it is necessary to initialize the image acquisition device corresponding to the image interface, and use software to create an image acquisition task for the image interface to specifically acquire the image data transmitted by the image interface and output it to the display screen. Based on this, in order to be able to normally acquire image data through the first image interface 110 or the second image interface 120, it is necessary to predetermine the activation status of the image acquisition tasks of the first image interface 110 and the second image interface 120, and before controlling one of the image interfaces to acquire image data, close the image acquisition task for the other image interface to avoid interference.

[0092] Specifically, when the first image interface 110 is connected to an image acquisition device, but the image acquisition task is started by the second image interface 120, it is necessary to first control the closing of the image acquisition task of the second image interface 120; when the first image interface 110 is not connected to an image acquisition device, but the image acquisition task is started by the first image interface 110, control the closing of the image acquisition task of the first image interface 110. Specifically, closing the image acquisition task of the image interface is to send a stop image acquisition command to the corresponding image interface, so that the image acquisition thread exits and stops outputting to the display screen. When an ISP chip is connected between the aforementioned image interface and the controller 130, the stop image acquisition command is specifically sent to the ISP chip corresponding to the image interface to close the image acquisition task.

[0093] This step can avoid the problem of image acquisition failure caused by the inconsistency between the image interface for image data acquisition and the image interface corresponding to the image acquisition task set by the software.

[0094] In some possible implementations,

[0095] When the first image interface 110 is connected to an image acquisition device, the step of controlling the acquisition of image data through the first image interface 110 may specifically include:

[0096] When the first image interface 110 is connected to an image acquisition device and the image acquisition task of the first image interface 110 is started, acquiring the image data from the first image interface 110;

[0097] When the first image interface 110 is connected to an image acquisition device and the image acquisition task of the first image interface 110 is not started, initializing and creating an image acquisition task for the first image interface 110 to acquire the image data from the first image interface 110;

[0098] When the first image interface 110 is not connected to an image acquisition device, the step of controlling the acquisition of image data through the second image interface 120 may specifically include:

[0099] When the first image interface 110 is not connected to an image acquisition device and the image acquisition task of the second image interface 120 is started, acquiring the image data from the second image interface 120;

[0100] When the first image interface 110 is not connected to an image acquisition device and the image acquisition task of the second image interface 120 is not started, the image acquisition task for the second image interface 120 is initialized and created to acquire the image data from the first image interface 110 .

[0101] In this embodiment, based on the above description, before the controller 130 acquires image data through the image interface, it is necessary to initialize the image acquisition device corresponding to the image interface, and use software to create an image acquisition task for the image interface. Among them, initializing the image acquisition device corresponding to the image interface includes: sending image setting parameters (brightness, saturation, sharpness, etc.) to the ISP, setting the image resolution, sending a command to start acquiring images, etc. Creating an image acquisition task means using software to create an image acquisition thread specifically to acquire endoscopic images and output them to the display screen.

[0102] To simplify the control logic, before the controller 130 acquires image data through the image interface, it can determine whether the image interface currently acquiring image data has started the image acquisition task. If it has been started, that is, the initialization and image acquisition task have been performed for the image interface, so when it is determined to use the image interface to acquire image data, the controller 130 can acquire image data from the image acquisition thread. If it is not started, it is necessary to perform the initialization and image acquisition task operations for the image interface first, and then acquire image data from the created image acquisition thread.

[0103] Specifically, when the first image interface 110 is connected to an image acquisition device and the image acquisition task of the first image interface 110 is turned on, image data is obtained from the first image interface 110; when the first image interface 110 is connected to an image acquisition device and the image acquisition task of the first image interface 110 is not turned on, an image acquisition task for the first image interface 110 is initialized and created to obtain image data from the first image interface 110. When the first image interface 110 is not connected to an image acquisition device and the image acquisition task of the second image interface 120 is turned on, image data is obtained from the second image interface 120; when the first image interface 110 is not connected to an image acquisition device and the image acquisition task of the second image interface 120 is not turned on, an image acquisition task for the second image interface 120 is initialized and created to obtain image data from the first image interface 110.

[0104] Through the above steps, while realizing automatic switching of the dual interfaces, it is possible to avoid the operation of initializing and creating an image acquisition task each time an image is acquired, thereby reducing the control logic of the software on the controller 130 and improving the operating efficiency.

[0105] In some possible implementations, when the first image interface 110 is connected to an image acquisition device, after the step of controlling the acquisition of image data through the first image interface 110, the controller 130 may also be configured to perform the following steps:

[0106] If it is determined that the image data acquisition has timed out, the device connection state of the first image interface 110 is re-determined.

[0107] In this embodiment, in view of the possible failure of the device during operation, when the acquisition of data through the first image interface 110 times out, the device connection state of the first image interface 110 may be determined again.

[0108] In some possible implementations, when the first image interface 110 is connected to an image acquisition device, after the step of controlling the acquisition of image data through the first image interface 110, the controller 130 may also be configured to perform the following steps:

[0109] If it is determined that the image data acquisition has timed out and the number of consecutive timeouts reaches a preset threshold, the first image interface 110 is reset.

[0110] In this embodiment, further, a preset threshold value can be set. When acquiring image data through the first image interface 110, the number of times can be recorded each time it times out. If the number of consecutive timeouts reaches the preset threshold value, a reset instruction can be sent to the first image interface 110 to instruct the corresponding ISP to reset. At this time, the controller 130 can also synchronously send an alarm instruction to the display 140 to prompt the user that the image acquisition of the first image interface 110 has timed out.

[0111] In some possible implementations, after the step of controlling the acquisition of image data through the second image interface 120 when the first image interface 110 is not connected to an image acquisition device, the controller 130 may also be configured to perform the following steps:

[0112] If it is determined that the image data acquisition has timed out, the display 140 is controlled to display a disconnection prompt of the image acquisition device.

[0113] In this embodiment, when the first image interface 110 is not connected and the image data acquisition of the second image interface 120 times out, the display 140 can be controlled to display a disconnection prompt of the image acquisition device to facilitate the user to check the device connection status.
