24 Color Classic Test Card As a professional color management tool, 24 color cards are mainly used for camera color calibration, image color restoration, and visual system color consistency testing. They are widely used in fields such as machine vision, photographic imaging, industrial inspection, printing, scientific research, and image algorithm research. The 24 color blocks on the color chart cover gray levels from deep to light and common high saturation colors. The back

The 11-Step Grayscale Card The 11-step grayscale card is a professional imaging testing tool primarily used to evaluate the grayscale reproduction capability of cameras. It assesses the fineness of the image's light and dark levels through 11 different brightness levels ranging from pure white to pure black. The common NHK standard gamma value is 0.45. It can also be equipped with blue, yellow, and red color blocks to assist in testing color saturation. 1. Core specifications

Lens Focusing Test Card The lens focusing test card is a specialized tool used for camera lens calibration. Its core function is to assist in completing lens focus calibration, back focal length detection, resolution verification, and to troubleshoot imaging problems such as pillow and barrel distortions. It is widely used for precision debugging in photography equipment, surveillance cameras, industrial vision, and other scenes. Its common design features a fan-shaped star

ISO 12233:2017 eSFR Enhanced Edition The Imatest enhanced version ISO 12233:2017 eSFR test card has all the functions of the ISO 12233 standard test card, maintaining a 3:2 aspect ratio, adding six tilted squares for measuring performance near image boundaries, and adding hyperbolic wedges for visual analysis or analysis using the eSFR ISO module. When generated using color supported technology, it also includes 16 color blocks. As these additional items are located in areas

ISO12233 Enhanced Resolution Test Chart 4000 Lines The ISO12233 4000 line is an enhanced resolution test chart that complies with the ISO 12233 standard, primarily used for testing the clarity and resolution performance of high-precision imaging devices. 1. Core features Based on the standard 2000-line test card, it adds a star pattern and 5° oblique edge elements, covering a resolution measurement range of 500-4000 lines/image height. The central area supports up to 4000

ISO 12233 Standard Test Card 2000 Line The core basis of the ISO12233 resolution test card is the international standard ISO 12233:2000 "Photography - Electronic still image cameras - Resolution measurement", which unifies the resolution measurement methods and judgment specifications for static electronic imaging equipment, and solves the industry Challenge of the lack of interoperability and comparability of resolution detection data in different devices and scenarios.
