Introducing the selected test chart from ImageEngineering!
When testing digital cameras, an important metric is resolution. The resolution that complies with ISO standard 12233 (digital still cameras) and ISO standard 16067 (scanners) refers to the ability of an image capture device to reproduce the details of the scene being photographed. What is important here is that the number of pixels is not the same as resolution. The number of pixels is necessary to achieve the required resolution, but not only optical components such as lenses and aliasing removal filters, but also image processing significantly affects the camera's resolution. Additionally, the smaller the number of pixels, the greater the impact of optical components on the resulting resolution. We offer the "TE253" sine wave Siemens star chart, which allows resolution analysis at nine positions within the image, as well as the "TE268" in our lineup. [Features] ■ Variable aspect ratio (TE253 9x) ■ Fixed aspect ratios: 4:3 and 3:2 (TE268) *For more details, please refer to the PDF document or feel free to contact us.
