The types of camera light sensors can be broadly divided into two categories: "global shutter" and "rolling shutter." The difference between these two lies in whether all the pixels of the sensor are exposed simultaneously (global shutter) or if they are exposed one line at a time from the top down (rolling shutter). How does this difference in mechanism affect the image? A typical example is the distortion shown below. When capturing a moving object, with a global shutter, a spherical object will be photographed as a sphere, but with a rolling shutter, because exposure occurs line by line from the top, the object may have moved during the exposure time, resulting in distortion. Thus, the differences between the two become apparent when photographing moving subjects. One might wonder, "Wouldn't it be better to use only global shutters?" However, in terms of manufacturing costs, rolling shutters are more advantageous (lower cost). (Figure 1: Left: Global Shutter, Right: Rolling Shutter)

basic information
Therefore, industrial cameras with more than 5 million pixels generally use a rolling shutter lineup. Many of the camera sensors in your smartphones also use rolling shutters. Finally, it is important to note that it is not necessarily the case that "if you are photographing moving objects, you must choose a global shutter." When capturing moving objects, distortion will naturally occur with a rolling shutter; however, in cases where you want to detect foreign objects on a moving sheet, the distortion of the foreign objects may not affect detection performance. The choice between a global shutter and a rolling shutter will depend on the application and cost, but if you can use a rental camera, I think it is a good idea to first test with a rolling shutter, and if it meets your needs, then continue using the rolling shutter. Skylogic also provides rental cameras, so please feel free to contact us.

Company information
"Achieve significant effects" while "keeping costs down." It requires endless effort despite its simplicity. This is why SkyLogic believes it is valuable to continue pursuing "cost-effectiveness" through means such as technology and services. EasyInspector2/DeepSky: An appearance inspection software with a cumulative installation record of 2,500. Effect: We have developed a high-precision and lightweight AI model. It can connect five cameras simultaneously to one PC. Cost: To reduce the cost of learning setup, it is no-code, and simply deciding the inspection mode determines the necessary processing. Expansion and horizontal deployment are possible at low cost. EasyMonitoring2: A system that accurately reads and records meters through cameras and notifies of abnormalities, eliminating time-consuming and costly patrol monitoring. Effect: Not only meter reading but also the confirmation of processing tanks and oil leaks can be automated using AI. Cost: It can connect to inexpensive cameras, up to 100, with one PC. There are no monthly fees. In addition to these, we offer various products for "cost-effectiveness." Please let us know your company's challenges and themes.
