Description

Technical Field

[0001] This utility model relates to the field of electronic camera technology, and in particular to a system for improving the clarity of dynamic target images captured by cameras. Background Technology

[0002] With the continuous development of electronic camera technology, electronic cameras have been widely used in various fields such as industry, agriculture, transportation, medicine, and scientific research. Their working principle involves projecting the light signal of the target object onto a CCD chip through an optical lens. The CCD chip then converts the light signal into electronic signals, which are transmitted to a monitor via transmission lines, ultimately displaying a dynamic image of the target object on the screen.

[0003] However, because CCD chips convert light signals into electronic signals through electronic scanning, acquiring each frame of an image takes approximately 1 / 25 of a second. If the target object moves during this time, the displayed image will appear blurry or ghosted, affecting image clarity. To address this issue, researchers have proposed various image processing techniques, such as image noise reduction, edge enhancement, and pixel augmentation. These techniques are typically applied when processing electronic signals. However, if the original light signal is already blurry, even with these processing methods, the final effect may be significantly reduced, or even fail to improve image quality.

[0004] The clarity of a video image largely depends on the quality of each still frame. Just like taking photos with a regular camera, only when each still image is sharp enough will the final video image be clear. Most traditional electronic cameras operate in continuous lighting conditions, and when the target object moves quickly, the image is prone to blurring, affecting observation and monitoring. Especially in some special situations, such as during medical surgery, this blurring can lead to serious adverse consequences.

[0005] Therefore, it is necessary to design a new system to improve the clarity of dynamic images captured by cameras and solve the problem of image blur. Utility Model Content

[0030] With the development of electronic imaging technology, electronic cameras are widely used in various fields. However, because CCD chips convert light signals through electronic scanning, the movement of the target object during image acquisition can easily cause blurring or ghosting, affecting image clarity. Although image processing techniques such as noise reduction and enhancement can improve the electronic signal, the effect is still limited if the original light signal is blurred. Especially in fast-moving or special environments, such as medical surgery, image blurring can have serious consequences; therefore, improving image clarity has become an important issue.

[0031] To address this issue, this invention provides a system for improving the clarity of dynamic target images captured by a camera. It addresses the problem at the source of optical imaging through continuous pulsed flash illumination synchronized with the camera field, thereby enhancing the clarity of dynamic images captured by the camera and resolving image blurring issues.

[0032] Specifically, this system improves the clarity of dynamic images captured by the camera and solves the problem of image blurring by having multiple components work together. Specifically, the system includes a camera unit 10, a signal extraction unit 20, a pulse generation unit 30, a switch control unit 40, an adjustment unit 50, and a light source 60. The camera unit 10 captures images of dynamic targets, the signal extraction unit 20 extracts synchronization signals, the pulse generation unit 30 generates continuous pulse signals, and the adjustment unit 50 controls the switch control unit 40 to adjust the brightness of the light source 60, thereby improving the brightness and clarity of the image. Furthermore, the system extracts synchronization signals through a synchronization separation module and converts digital signals into analog signals through a DA conversion module to ensure the stability of the image signal. The pulse generation unit 30 also optimizes the signal width through the adjustment module, further improving image clarity.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Please see Figure 1 A system for improving the clarity of dynamic target images includes: a camera unit 10, a signal extraction unit 20, a pulse generation unit 30, a switch control unit 40, an adjustment unit 50, and a light source 60; the camera unit 10 is connected to the signal extraction unit 20; the pulse generation unit 30 is connected to both the signal extraction unit 20 and the switch control unit 40, and the switch control unit 40 is connected to both the adjustment unit 50 and the light source 60; the camera unit 10 captures dynamic target images, and the signal extraction unit 20 extracts synchronization signals; the pulse generation unit 30 generates continuous pulse signals, and the adjustment unit 50 controls the switch control unit 40 to adjust the brightness of the light source 60 to achieve continuous flashing.

[0035] In this embodiment, the light source 60 includes at least one of LED, xenon lamp, and laser.

[0036] The light source 60 can be different light sources such as LED, xenon lamp, and laser depending on the application. The circuit in this embodiment can also be replaced with other continuous pulse flash illumination that can achieve strobe operation to improve the dynamic image of the camera and start from the source of optical imaging, synchronized with the camera field. Circuits that improve the clarity of the dynamic image captured by the camera and solve the problem of image blur are all within the protection scope of this application.

[0037] In this embodiment, the camera unit 10 is the core component of the system, responsible for capturing images of moving targets. It can be any standard electronic camera device, including CCD sensors or CMOS sensors, etc. This unit captures dynamic scenes with a fast exposure time (e.g., 1 millisecond), and can still obtain clear images even when the target is moving at high speed.

[0038] The main function of the signal extraction unit 20 is to extract synchronization signals from the signals output by the camera unit 10. These synchronization signals include field synchronization signals, used for precise synchronization with the flash timing of the stroboscopic source. Extraction of the synchronization signals is crucial, ensuring that the stroboscopic source flashes accurately the instant the camera unit 10 captures the image, thus avoiding image blur. The signal extraction unit 20 typically consists of a synchronization separation circuit capable of extracting synchronization signals (50Hz or 60Hz) from the camera's video signal.

[0039] The main function of the pulse generation unit 30 is to generate continuous pulse signals to drive the strobe light source. It receives the synchronization signal from the signal extraction unit 20 and generates a pulse signal lasting 1 millisecond at each field synchronization moment. The width of the pulse signal can be precisely controlled by adjusting the relevant resistor (e.g., resistor R2 mentioned in the figure) to meet the needs of different applications. The pulse generation unit 30 can use electronic components such as a 555 timer to generate precise rectangular pulse signals.

[0040] The function of the switch control unit 40 is to control the switching of the light source 60 based on pulse signals. It receives rectangular pulse signals from the pulse generation unit 30 and transmits the signals to the light source 60 through a switching transistor (such as IRF3205) to turn the strobe light source on or off. In the circuit, the switching transistor plays the role of signal transmission and controlling the current flow to the light source 60, ensuring that the flashing time of the light source is synchronized with the camera's shooting.

[0041] The adjustment unit 50 is used to control the brightness of the light source 60. The brightness of the strobe light source can be adjusted by regulating the voltage of the LED (e.g., via an adjustable voltage plate). Different brightness settings can be adjusted according to the needs of the shooting environment; for example, increasing brightness in a darker environment and decreasing brightness in a brighter environment. The adjustment unit 50 typically includes circuit components such as a voltage regulator for precise control of the LED brightness.

[0042] The light source 60 is the illumination component of the system, providing a high-brightness strobe light source, typically a xenon lamp, LED, or laser. In this embodiment, an LED is chosen as the strobe light source. The LED's flash cycle is synchronized with the camera to ensure clear capture of dynamic target images. In practical applications, the flash frequency of the light source 60 is usually set to 50Hz or 60Hz, with each flash lasting 1 millisecond. By adjusting the brightness of the light source 60, image clarity requirements under different environmental conditions can be met.

[0043] The specific working principle is as follows:

[0044] The camera unit 10 captures images of moving targets, utilizing high-speed exposure times to ensure clear rendering of fast-moving objects. The signal extraction unit 20 extracts a field synchronization signal from the output signal of the camera unit 10, used to control the flashing timing of the stroboscopic light source. The pulse generation unit 30 generates a 1-millisecond rectangular pulse based on the synchronization signal and precisely controls the flashing timing of the light source. The switch control unit 40 controls the flashing of the light source based on the pulse signal, while the adjustment unit 50 adjusts the brightness of the light source to optimize the shooting effect. Ultimately, the electronic camera obtains clear images of moving targets through precise illumination from the stroboscopic light source, ensuring that images of fast-moving objects are no longer blurry.

[0045] Through the coordinated work of the above-mentioned units, this invention can significantly improve the clarity of dynamic target images and is applicable to fields such as high-speed moving object photography, industrial and agricultural monitoring, and endoscopic imaging.

[0046] In one embodiment, please refer to Figure 1 The signal extraction unit 20 mentioned above includes a synchronization separation module, which is used to extract field synchronization signals from the full television analog signal.

[0047] In this embodiment, one of the core components of the signal extraction unit 20 is the synchronization separation module, which is used to extract the field synchronization signal from the full television analog signal output by the camera. By parsing the field synchronization signal from the analog signal, the synchronization separation module ensures that the system can accurately trigger the flash source based on the timing of the video signal. The field synchronization signal is typically used to define the field and frame structure in a video image, which is crucial for synchronized flash, as the capture of each field or frame needs to be aligned with the flash timing to avoid image blurring.

[0048] In one embodiment, please refer to Figure 1 The signal extraction unit 20 described above also includes a DA conversion module, which converts the digital signal output by the camera unit 10 into a full television analog signal. If the camera has a field synchronization signal output terminal, the DA conversion module is not required.

[0049] In this embodiment, to ensure compatibility with camera output signals of different formats, the signal extraction unit 20 also includes a DA conversion module. The digital signal output by the camera needs to be converted into a full-screen analog signal by the DA conversion module in order to connect with the synchronization separation module. This module ensures that the system can obtain a suitable synchronization signal for flash control regardless of whether the camera outputs a digital or analog signal.

[0050] In one embodiment, please refer to Figure 1 The aforementioned adjustment unit 50 includes a switching power supply and an adjustable voltage board. The switching power supply is connected to the adjustable voltage board, and the adjustable voltage board is connected to the switch control unit 40.

[0051] In this embodiment, one of the core components of the regulating unit 50 is the switching power supply, which is responsible for providing a stable voltage to the entire system, especially the LED flash source. The switching power supply converts the AC power (e.g., 220V) from the mains into DC power (e.g., 12V) suitable for LED use. In this process, the switching power supply also has a high-efficiency power conversion capability, ensuring that the LED can obtain a stable power supply.

[0052] The adjustable voltage board connects to the switching power supply and is responsible for regulating the LED's supply voltage, thereby controlling the LED's brightness. By adjusting the voltage, fine adjustments can be made to the LED flash brightness, ensuring ideal lighting effects in different shooting environments.

[0053] In one embodiment, please refer to Figure 1 The aforementioned switch control unit 40 includes a switch transistor.

[0054] In this embodiment, the switch control unit 40 includes a switching transistor, typically a high-power switching transistor (such as a MOSFET) to control the switching of the LED. The switching transistor determines the timing of the LED's on and off by receiving a pulse signal (generated by a pulse generation module). The function of the switching transistor is to accurately trigger the LED's flashing according to the synchronization signal, ensuring that the duration of each flash is 1 millisecond and synchronized with the camera's field synchronization signal. The operation of the switching transistor ensures that the LED flashes correctly according to the synchronization signal, thereby providing necessary illumination for the camera and avoiding image blurring.

[0055] In this embodiment, through the coordinated operation of these key modules, the system can achieve high-precision capture of dynamic scenes. The synchronization separation module ensures precise signal synchronization, the DA conversion module makes the system compatible with different types of signal inputs, the switching power supply and adjustable voltage board ensure stable power supply to the LED and adjust its brightness, while the switching transistor is responsible for precisely controlling the flashing timing of the LED. Through these technical means, the system can achieve efficient and stable dynamic image capture, suitable for a variety of high-precision monitoring applications.

[0056] In one embodiment, please refer to Figure 2 The aforementioned synchronization separation module includes a synchronization separation chip, model LM1881. This chip's function is to extract the field synchronization signal from the video signal output by the camera. The specific operation is as follows:

[0057] The camera's full-video analog signal (such as VEDIO IN) is input to pin 2 of the LM1881 synchronization decoupling chip through isolation capacitor C1.

[0058] The field synchronization signal output from pin 7 of the LM1881 chip can be used to trigger the downstream pulse generator. This synchronization signal ensures that the strobe light source is synchronized with the camera's shooting cycle, guaranteeing a clear image.

[0059] In one embodiment, please refer to Figure 2 The pulse generation unit 30 mentioned above includes a pulse generator. Typically, integrated circuits (such as a 555 timer chip) are used to generate precise rectangular pulse signals.

[0060] In this embodiment, the pulse generator triggers pulse generation by receiving a field synchronization signal from the synchronization separation module.

[0061] The pulse generator outputs a rectangular pulse signal with a width of 1 millisecond. This pulse signal controls the flashing time of the strobe light source (such as an LED), thereby ensuring that the image exposure time is accurate and synchronized.

[0062] In one embodiment, please refer to Figure 2 The pulse generating unit 30 also includes a width adjustment module connected to the pulse generator. By adjusting the pulse width, the flashing time of the stroboscopic light source can be precisely controlled. This module includes an adjustable resistor (R2), and by adjusting the resistance value of R2, the pulse width can be changed, thereby controlling the duration of the stroboscopic light.

[0063] The width adjustment module is connected to the pulse generator. By adjusting the size of R2, users can adjust the flash duration of the strobe source in different applications to adapt to different shooting needs.

[0064] In one embodiment, please refer to Figure 2 The pulse generator mentioned above is also connected to a transistor Q1, which is connected to the switch control unit 40.

[0065] In this embodiment, the transistor Q1 is used as part of the switch control unit 40 to amplify and control the current in order to drive the LED strobe light source.

[0066] The rectangular pulse signal output by the pulse generator is transmitted to the base of transistor Q1 through isolation capacitor C5, thereby turning Q1 on or off and controlling the current flow to the LED.

[0067] The signal output from the emitter of Q1 is transmitted to the base of the switching transistor IRF3205 through the isolation capacitor C6, thereby controlling the LED to light up.

[0068] The IRF3205 switching transistor is used to actually control the switching of LEDs, providing sufficient current to drive the LEDs to emit light.

[0069] This embodiment ensures that the LED strobe light source can work synchronously with the camera signal through the cooperation of the synchronization separation module, pulse generation unit 30, width adjustment module, and switch control unit 40. Throughout the process, the pulse generator is triggered by the synchronization signal, the width adjustment module precisely controls the flash duration, and the transistor Q1 and the switching transistor drive and control the LED. This process effectively solves the synchronization problem between the light source and image acquisition during high-speed shooting, thereby obtaining clear dynamic images.

[0070] The system in this embodiment improves upon the acquisition process of the image source, namely the "primary signal" image. This improvement stems from everyday experience photographing moving objects, such as the moment of a 100-meter sprint. To ensure image clarity, it's typically necessary to increase the camera's shutter speed or use a flash; otherwise, the photo will be blurry. Therefore, if a high-speed shutter or flash is used on an electronic video camera, the captured moving images should also be clear.

[0071] The use of a stroboscopic xenon lamp cold light source for illumination yielded clear and satisfactory images, thus providing strong support for microcirculatory blood flow velocity testing. Similarly, this method can also achieve significant results in fields such as industrial and agricultural production, traffic monitoring, endoscopic image stabilization, and improving image clarity.

[0072] The illumination sources used include xenon lamps, LEDs, and lasers. If the electronic camera's video signal uses interlaced scanning, meaning one frame consists of two fields, then the illumination source must match the field synchronization signal. Typically, the field synchronization signal frequency of an electronic camera is 50Hz or 60Hz; therefore, the flash frequency of the stroboscopic source should be synchronized with it. Generally, when shooting fast-moving objects, the camera shutter speed needs to be at least 1 / 800 of a second; therefore, we chose a flash duration of 1 / 1000 of a second, meaning the flash duration of the stroboscopic source is 1 millisecond.

[0073] Under 1 millisecond flash illumination, the CCD chip can capture and store complete image information, and then scan each pixel one by one to complete frame-by-frame moving images. In this way, even under 1 millisecond flash illumination, a complete image can be obtained, eliminating concerns about incomplete images.

[0074] For different light sources such as xenon lamps, LEDs, or lasers, when using a stroboscopic light source, their repetition frequency can be 50Hz or 60Hz, and the flash time is 1 millisecond. These light sources can be implemented in various ways. Taking an LED stroboscopic light source as an example, a feasible implementation is as follows: the video signal output from the electronic camera is processed by a synchronization splitter to extract the field synchronization signal, which then triggers a pulse generator to generate a 1-millisecond rectangular pulse signal. This pulse signal is then used to control the LED flash through a high-power switching transistor, while the LED is powered by a voltage regulator. This allows the stroboscopic light source to be synchronized with the electronic camera, possessing a repetition frequency of 50Hz or 60Hz and a flash time of 1 millisecond, and also allowing for adjustment of the flash brightness.

[0075] Specifically, the video signal output by the camera can be a digital signal or a full television analog signal in various formats. If it is a digital signal, it needs to be converted into a full television analog signal through a paired DA conversion unit; if it is an analog signal, no DA conversion is needed, and it is directly input to the synchronization separation unit to obtain the field synchronization signal. Then, this signal triggers the pulse generation unit 30 to generate a 1-millisecond rectangular pulse, which controls the flashing of the LED light through a switching transistor. The LED is powered by a switching power supply, and the voltage is adjusted by an adjustable voltage plate to change the brightness of the LED.

[0076] Specifically, please refer to Figure 2 The aforementioned camera's full television analog signal (VEDIO IN) is input to pin 2 of the LM1881 sync splitter chip via isolation capacitor C1. Pin 7 outputs a field sync signal, which is input to pin 2 of the 555 pulse generator. Pin 3 of the pulse generator outputs a 1-millisecond rectangular pulse. The width of the rectangular pulse can be changed by adjusting the resistance of R2. The pulse signal is transmitted to the base of the S9014 transistor via isolation capacitor C5, and the emitter output is transmitted to the base of the IRF3205 switching transistor via isolation capacitor C6. The emitter is connected to the LED. The power supply provides 12V DC voltage through a switching AC-DC power supply, and the LED's power supply voltage is adjusted by an adjustable voltage board XL4016E1, thereby adjusting the flash brightness. All components before the switching transistor are powered by a 5V DC power supply.

[0077] In one embodiment, the above-described system is applied to endoscopic illumination scenarios, employing flash illumination synchronized with the electronic camera field to fundamentally improve the image clarity of moving objects captured by the endoscope. Currently, endoscopes both domestically and internationally generally use traditional continuous light illumination, which often results in blurred images due to the movement of the operator and the observed object during examinations, diagnoses, and minimally invasive surgeries. Therefore, avoiding image blurring and improving the clarity of endoscopic images has become particularly crucial. This embodiment breaks through the traditional method of improving image clarity through electronic image processing, providing a significantly improved image clarity when capturing moving objects using synchronized flash illumination.

[0078] Please see Figure 3 and Figure 4 To verify the effectiveness of stroboscopic light sources in improving the image clarity of moving objects in video recordings, a simulation device was designed. The device operates as follows: 220V AC mains power is converted to 12V DC power via a switching power supply. Then, a speed control board with a digital display adjusts the speed of a DC motor, driving a high-speed rotating blade to simulate a rapidly moving object. In the first stage, a conventional continuous light source illuminates the blade while recording video. In the second stage, maintaining the same speed, a stroboscopic light source is used for continuous flash illumination, and video recording is repeated. Afterward, a frame from each video clip is extracted using computer video analysis software for comparative analysis. The results show that the stroboscopic light source significantly improves image clarity, clearly displaying the outline of the high-speed rotating blade, while a conventional continuous light source fails to clearly present the blade's outline.

[0079] The camera unit 10 captures dynamic target images and extracts synchronization signals through the signal extraction unit 20. The pulse generation unit 30 generates continuous pulse signals, which, together with the adjustment unit 50, control the switch control unit 40 to adjust the brightness of the light source 60.

[0080] The aforementioned system for improving the clarity of dynamic target images enhances the clarity of images captured by the camera through the coordinated operation of multiple components. First, the camera unit 10 captures the dynamic target image. After the signal extraction unit 20 extracts the synchronization signal, the pulse generation unit 30 generates a continuous pulse signal, which, in conjunction with the switch control unit 40, adjusts the brightness of the light source 60. By synchronously triggering the camera's image acquisition through the strobe light source, it ensures that the image can be completely captured instantly under high-speed movement, avoiding blurring problems caused by excessive exposure time or excessively fast movement speed, thereby significantly improving the clarity of dynamic images.

[0081] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
