Description

Technical Field

[0001] This invention relates to the field of photographic equipment calibration technology, specifically to a modular photographic parameter testing system. Background Technology

[0002] During the testing, calibration, and maintenance of photographic equipment, it is usually necessary to measure photographic parameters such as shutter speed, exposure time, or shutter curtain movement to assess the actual working condition of the photographic equipment.

[0003] Existing photographic parameter testing systems mostly adopt a fixed structure design, and their sensor type and measurement method are determined during the equipment manufacturing stage. It is difficult to make flexible adjustments according to different testing needs. When different types of photographic parameters need to be tested, it is often necessary to replace the entire set of testing equipment or use multiple different testing instruments, resulting in high equipment costs and inconvenience in use.

[0004] Furthermore, while some existing technologies extend testing functionality through software, their hardware architecture still lacks versatility, making it difficult to support rapid switching between different sensing structures or measurement methods. This limits the applicability and scalability of photographic parameter testing systems. To address this, we propose a modular photographic parameter testing system. Summary of the Invention

[0005] To address the aforementioned technical problems, a modular photographic parameter testing system is provided, which solves the problems described above.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: a modular photographic parameter testing system, comprising: The main control module includes a processing unit, which is used to process the test data output by the adaptable sensor panel module through the standardized panel interface module to the analysis module for processing, based on the type of the connected adaptable sensor panel module, to obtain the corresponding photographic parameter test results, and output the test results to the display interaction module; at the same time, it receives operation instructions sent by the display interaction module to control the coordinated work of each module. It can be adapted to the sensor panel module and connected to the main control module through a standardized panel interface module to acquire test signals related to photographic exposure and transmit the test signals to the analysis module. A standardized stand-up panel interface module is used to establish an electrical connection between the adaptable sensor stand-up panel module and the main control module, so as to realize the power supply, control and test data transmission of the adaptable sensor stand-up panel module. The analysis module receives test signals through the standardized vertical plate interface module and analyzes and processes the digital signals. The display interaction module is used to obtain test reports from the main control module, visualize them, and receive user input commands.

[0007] Preferably, the testing system includes a main control unit and multiple sensor plate adapters; the sensor plate module is a replaceable structure, and different types of sensor plate modules are used to acquire different types of photographic exposure-related measurement signals; the sensor plate module includes at least two spatially separated optical sensing units for acquiring the differences of the same exposure event at different spatial locations or times; the processing unit is configured to select the corresponding photographic parameter testing method according to the type of the sensor plate module; the photographic parameter testing results include any one or a combination of the following: shutter speed parameters, exposure-related time parameters, and shutter curtain motion-related parameters.

[0008] Preferably, the standardized vertical panel interface module includes a standardized mechanical interface and a standardized electrical interface; the standardized mechanical interface adopts a snap-fit, threaded, or magnetic connection structure.

[0009] Preferably, the adaptable sensing panel module includes an exposure sensing unit and a signal conversion unit; the exposure sensing unit is used to acquire test signals related to photographic exposure; the signal conversion unit is used to convert the acquired analog test signals into digital test signals and transmit the converted digital test signals to the main control module.

[0010] Preferably, the display interaction module integrates the acquired report information based on a preset report template and outputs an exportable test report.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through its modular structural design, enables the same main control module to be compatible with various types of sensor panel modules, reducing the cost of using the photographic parameter testing system. When expanding testing functions, only the corresponding sensor panel module needs to be replaced, without replacing the entire testing equipment. It can test shutter speed, exposure-related time parameters, and shutter curtain motion-related parameters. The structure is simple, easy to implement and maintain, and the detachable panel interface structure facilitates assembly, maintenance, and functional expansion. Attached Figure Description

[0013] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figure 1 As shown, a modular photographic parameter testing system includes: The main control module includes a processing unit, which is used to process the test data output by the adaptable sensor panel module through the standardized panel interface module to the analysis module for processing, based on the type of the connected adaptable sensor panel module, to obtain the corresponding photographic parameter test results, and output the test results to the display interaction module; at the same time, it receives operation instructions sent by the display interaction module to control the coordinated work of each module. It can be adapted to the sensor panel module and connected to the main control module through a standardized panel interface module to acquire test signals related to photographic exposure and transmit the test signals to the analysis module. A standardized stand-up panel interface module is used to establish an electrical connection between the adaptable sensor stand-up panel module and the main control module, so as to realize the power supply, control and test data transmission of the adaptable sensor stand-up panel module. The analysis module receives test signals through a standardized vertical panel interface module and analyzes and processes the digital signals. The display interaction module is used to obtain test reports from the main control module, visualize them, and receive user input commands.

[0015] This application system adopts a modular architecture, with each module performing its own function and working collaboratively. The main control module's processing unit uniformly schedules instructions, ensuring a closed-loop, efficient operation of testing from environmental simulation and signal acquisition to result output, reducing human error. Each module is independent, facilitating later maintenance and functional upgrades without requiring system reconstruction. It can be adapted to sensor panel modules for precise acquisition of exposure-related test signals, with efficient and lossless transmission, ensuring data source accuracy. A standardized panel interface module allows for detachable connection of sensor panels, adapting to multiple panels equipped with different sensors to test different parameters, or to panels with different structures to test different photographic equipment, improving system reusability and reducing hardware investment. The analysis module automatically completes data processing, parameter comparison, and test report generation, improving efficiency and avoiding subjective errors, ensuring objective and accurate results. The display and interaction module enables test control and result visualization, simplifying the operation process, lowering the professional threshold, and facilitating quick interpretation of test results. The overall system is adaptable to the entire process of R&D, production, and after-sales service, combining practicality and scalability, significantly improving the efficiency, accuracy, and standardization of photographic equipment testing, and reducing testing costs.

[0016] The adaptable sensor panel module is a replaceable structure, and different types of adaptable sensor panel modules are used to acquire different types of photographic exposure-related measurement signals; the adaptable sensor panel module includes at least two spatially separated optical sensing units; the processing unit is configured to select the corresponding photographic parameter testing method according to the type of the adaptable sensor panel module; the photographic parameter testing results include any one or a combination of the following: shutter speed parameters, exposure-related time parameters, and shutter curtain motion-related parameters.

[0017] This application adopts a replaceable structure, allowing for the replacement of corresponding adaptable sensor modules based on the model and function of the photographic equipment under test. This enables the acquisition of different types of photographic exposure-related measurement signals, overcoming the limitations of traditional fixed sensor modules that can only test a single type of equipment and a single exposure signal. This allows a single testing system to be adapted to test more types of photographic equipment with more functional requirements, further improving system reusability and reducing hardware investment. At least two spatially separated optical sensing units can simultaneously acquire photographic exposure-related test signals from different angles and positions, reducing the limitations and errors of single-sensor unit acquisition and avoiding test result deviations due to incomplete signal acquisition. This provides a more comprehensive and accurate data source for subsequent analysis modules' data analysis and parameter calculations, ensuring the reliability of test results.

[0018] The standardized vertical panel interface module includes a standardized mechanical interface and a standardized electrical interface; the standardized mechanical interface adopts a snap-fit, threaded, or magnetic connection structure.

[0019] This application enhances the versatility, stability, and testing accuracy of the photographic equipment testing system. It seamlessly integrates with the advantages of the replaceable sensor stand and intelligent adaptive testing method mentioned earlier, significantly improving the system's practicality. The standardized stand interface module adopts standardized mechanical and electrical dual interfaces. The snap-on or threaded design of the mechanical interface enables quick disassembly and assembly of the sensor stand while ensuring a secure connection, avoiding test interruptions. The standardized electrical interface adapts to different testing scenarios, improving signal transmission efficiency and system compatibility.

[0020] The adaptable sensor panel module includes an exposure sensing unit and a signal conversion unit; the exposure sensing unit is used to acquire test signals related to photographic exposure, including but not limited to signals corresponding to exposure, shutter speed, and aperture size; the signal conversion unit is used to convert the acquired analog test signals into digital test signals and transmit the converted digital test signals to the analysis module.

[0021] This application further improves the "acquisition-conversion-transmission" link of the test signal, making up for the shortcomings of the original signal acquisition being not specific and the format not being compatible. It forms an efficient synergy with the replaceable structure, dual optical sensing unit and analysis module mentioned above. The exposure sensing unit accurately focuses on the core signal, improving the targeting and comprehensiveness of the acquisition. This unit clearly focuses on the test signals corresponding to the three core exposure parameters of exposure amount, shutter speed and aperture size. Compared with the original general exposure-related signal acquisition, the acquisition range is more specific and more targeted. It can completely capture the key data of the exposure performance of the photographic equipment, avoid the omission of core parameter signals, and provide a more comprehensive and targeted data source for the subsequent analysis module to accurately calculate the test results, making the test results more consistent with the actual exposure performance of the equipment.

[0022] The interactive display module integrates the acquired report information based on a preset report template and outputs an exportable test report.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
