"Industrial camera brand" introduction to the scanning method of industrial cameras 2026-08-24 .gtr-container-a7b2c9 { font-family: Verdana, Helvetica, "Times New Roman", Arial, sans-serif; color: #333333; line-height: 1.6; padding: 16px; box-sizing: border-box; } .gtr-container-a7b2c9 { --primary-color: #0000FF; --primary-light: #E0E0FF; --primary-dark: #0000CC; --text-color: #333333; --heading-color: #1A1A1A; --border-color: #CCCCCC; --accent-color: #0000FF; } .gtr-container-a7b2c9 p { font-size: 14px; margin-bottom: 1em; text-align: left !important; word-break: normal; overflow-wrap: normal; } .gtr-container-a7b2c9 .gtr-section-title { font-size: 18px; font-weight: bold; color: var(--heading-color); margin-top: 2em; margin-bottom: 1em; padding-bottom: 0.5em; border-bottom: 2px solid var(--primary-light); } .gtr-container-a7b2c9 .gtr-highlight { font-weight: bold; color: var(--accent-color); } .gtr-container-a7b2c9 .gtr-section + .gtr-section { margin-top: 2.5em; } @media (min-width: 768px) { .gtr-container-a7b2c9 { padding: 24px; max-width: 960px; margin: 0 auto; } } Interlaced Scanning A frame requires two passes to scan, the first pass scans only odd-numbered lines, and the second pass only scans even-numbered lines. This scanning method is interlaced scanning. There are three problems that traditional interlaced scanning cannot solve. The field frequency is close to the frequency at which the human eye is sensitive to flicker, and obvious flickering will be felt when viewing a large-area light-colored background picture; the odd-even cycle of interlaced scanning results in obvious inter-scan line flicker, which is most obvious when viewing text information; the odd-even cycle of interlaced scanning causes the picture to show obvious and neatly arranged row structure lines, and the larger the screen size, the more obvious the row structure lines will be, affecting the reflection of picture details and the overall picture effect. Progressive Scanning In the progressive scanning mode, each frame is composed of several horizontal scanning lines. If all the lines in this frame are completed one row after another from top to next, we call this scanning mode progressive scanning. Progressive scanning has non-linear signal processing technology to achieve accurate motion detection and motion compensation, thereby overcoming the three major shortcomings of traditional scanning methods. We can make a comparison. In interlaced scanning, odd-numbered lines are scanned first, and then even-numbered lines are scanned in the next 50th of a second. However, progressive scanning completes scanning of the entire image in 1/50th of a second. The picture scanned out line by line is clear and flicker-free, and the dynamic distortion is small. If used in conjunction with progressive scan TV and digital high-definition TV, you can achieve picture quality comparable to movies per second.

Therefore, Gigabit network industrial cameras are quite simple to use and operate, which can save people a lot of unnecessary trouble. Gigabit network industrial cameras can use Gigabit network cables to achieve simultaneous operation of power supply and data transmission, thus saving a lot of costs. Let people choose with confidence. In addition, Gigabit industrial cameras also have high data transmission rates and have a wide range of applications in industrial sites, further promoting the rapid development of industry. Gigabit network industrial cameras use PoE system devices for installation and use, so they can be suitable for specific applications in limited spaces, and the installation is also very fast and efficient. Gigabit network industrial cameras also have the advantages of high standardization and easy integration. They can integrate different functions and can be used well with other equipment, which can create extremely high economic benefits for users. Gigabit network industrial cameras also have longer transmission distance performance to meet the different actual needs of users. In this way, we can operate the camera from a long distance and observe the data captured by the camera in real time.
How to solve the frame loss problem of industrial cameras in "Machine Vision System" 2026-08-24 .gtr-container-p9q2r5 { font-family: Verdana, Helvetica, "Times New Roman", Arial, sans-serif; color: #333; line-height: 1.6; padding: 20px; box-sizing: border-box; max-width: 100%; overflow-x: hidden; } .gtr-container-p9q2r5 .gtr-title { font-size: 18px; font-weight: bold; color: #0000FF; margin-bottom: 25px; text-align: left; } .gtr-container-p9q2r5 .gtr-reason-heading { font-size: 16px; font-weight: bold; color: #333; margin-top: 25px; margin-bottom: 10px; text-align: left; } .gtr-container-p9q2r5 p { font-size: 14px; text-align: left; line-height: 1.6; margin-bottom: 15px; color: #333; } .gtr-container-p9q2r5 .gtr-highlight { font-weight: bold; color: #0000FF; padding: 10px 15px; border-left: 4px solid #0000FF; background-color: rgba(0, 0, 255, 0.05); margin-top: 20px; margin-bottom: 20px; border-radius: 4px; text-align: left; } @media (min-width: 768px) { .gtr-container-p9q2r5 { padding: 30px; max-width: 960px; margin: 0 auto; } .gtr-container-p9q2r5 .gtr-title { font-size: 20px; margin-bottom: 30px; } .gtr-container-p9q2r5 .gtr-reason-heading { font-size: 18px; margin-top: 30px; margin-bottom: 12px; } .gtr-container-p9q2r5 p { font-size: 14px; margin-bottom: 18px; } .gtr-container-p9q2r5 .gtr-highlight { padding: 12px 20px; margin-top: 25px; margin-bottom: 25px; } } Three main reasons why industrial cameras drop frames: 1. Industrial vision software application part Vision software has a buffering mechanism for waiting for image space calculations. In order to increase the image buffering time, the program operations can be processed. However, if the computer CPU processing speed is slower than the image speed, it will cause the cache space to be overloaded and frame loss problems will occur. Industrial camera drops frames 2. Hardware design of the industrial camera itself Industrial cameras convert images from optical signals into ordered electrical signals. The image sensor transmits the image to the USB chip on the camera, and the USB transmits the image to the computer. If the computer terminal system is busy at a certain moment, the image cannot be received in time, and subsequent images are transmitted, resulting in the loss of the unreceived part of the image. Industrial cameras require memory buffer space, otherwise frame drops will occur. 3. Hardware PC system part The PC part mainly relies on hardware drivers. The most important thing is the power of the driver and how many threads in the system have core mode to divide the CPU time. The received power is not good, and the industrial camera does not have a good buffer memory, which often causes frame loss. Industrial camera drops frames In machine vision systems, the frame rate of industrial cameras is often very large, and the cache of industrial cameras is also limited. This is mainly an auxiliary function for temporary busy processing of the scheduling system. The speed of machine vision software is slower than the speed of industrial camera images. After a long period of time, it will cause the loss of software buffer saturation and overflow. Therefore, frame loss will occur in both USB interfaces and GigE interfaces. Therefore, it is very important to optimize the processing speed of machine vision software.
