    Industrial Camera: CCD vs CMOS Image Sensor

    Image sensor is an important part of the industrial camera. According to difference of the original, it can be divided into CCD and CMOS sensors. In the last 25 years of the last century, CCD technology has been leading the trend of the imaging sensor. It is a high-resolution and high-quality image sensor which can be integrated on a very small chip. However, in recent years, with the rapid development of the semiconductor manufacturing technology, the size of the integrated transistor is becoming smaller and smaller, and the performance is much better. CMOS image sensor obtains rapid development in the recent years, and it seems CMOS image sensor has overtaken CCD image sensor. CMOS provides the performance on a par with CCD in the mid-end and low-end applications, and has a significant advantage in price. With the development of technology, CMOS will also occupy a space in the high-end application field. This paper makes a detailed explanation to the difference between CCD and CMOS image sensors in the industrial camera.

    Why Industrial Cameras Lose Frame?

    The problem why the frame loss of the industrial camera occurs is indeed caused by the blockage of the material channel, so it is unable to be processed by the technology. Therefore, when the new images are collected, the former image might be forced to be abandoned, or the new image will probably be forced to be abandoned. Generally speaking, the frame loss of the industrial camera is not related to the transmission interface adopted by the industrial camera. For USB, 1394, GigE, or camera-link, the poorly designed driving program or industrial camera hardware is the true reason of frame loss. In order to solve this problem, the designers are required to conduct precision design to every link of the driving program and industrial camera hardware material transmission.

    How to Choose a Right Lens for Industrial Camera?

    Industrial camera is a key component in the machine vision system. Its most essential function is to convert the optical signal into the ordered electrical signal of the small-size high-definition industrial camera. In the machine vision system, the lens of the industrial camera are equivalent to the eyes of human beings. Its main function is to focus the targeted optical images on the photo surface of the image sensor (industrial camera). All image information of the visual system treatment can be obtained from the lens of industrial camera. The lens quality of the industrial camera will directly affect the entire performance of the visual system. As an image device, the lens of industrial camera usually constitute a complete image collecting system with the power source and camera. Therefore, the lens selection of the industrial camera is restrained by the entire system requirement. Generally, it can be analyzed and considered as the following aspects.

    Industrial Camera for High Speed Image Capture

    In the visual inspection of industrial machine, there are usually projects requiring to capture the objects in high-speed movement. However, the ordinary industrial camera will probably problems of vague or deformed pictures, thus failing to reach the project requirements of the customers. At this time, high-performance industrial camera is required to solve such problems. Then, we will illustrate it by taking the high-speed image capturing of the industrial camera as an example.

    Interlaced vs. Progressive Scanning of Industrial Camera

    Industrial camera can be divided into interlaced scanning industrial cameras and progressive scanning industrial camera according to scanning mode.
    Most displays and industrial cameras adopt the interlaced scanning, but it actually looks like a smooth image in human eyes. Industrial cameras usually get odd rows of images first, for CCIR standard, industrial cameras get the even rows after 1/50 seconds, but for EIA standard, the industrial cameras get the even rows after 1/60 seconds.
