It is the world's first glossiness meter to use a 3.5-inch large screen display, with the characteristics of easy use, stable performance, and accurate measurement.

purpose

Resolution card (resolution card) is a standard sample that can provide auxiliary testing such as vertical resolution and horizontal resolution for actual shooting.

The resolution test was conducted using the international standard ISO12233 resolution card, with a unified shooting angle and shooting environment,

The calculation of resolution was carried out using HYRes software, which separates vertical resolution and horizontal resolution.

The evaluation of digital cameras is different from other products, unlike laptops, DIY, etc. which have a large amount of software to test objective data, which can explain everything from the data. Evaluating the quality of a digital camera requires not only objective data, but also practical usage and sample photography. Therefore, our evaluation is based on the principle of objective data, combined with the rational analysis of experienced evaluators, in order to obtain the most objective evaluation results.

The ISO 12233 standard resolution test card follows the 12233 standard "Photography - Electronic Photographic Images - Measurement Methods". In this active area of 1 X size, measuring a height of 20 cm has an error of only about 0.1 millimeters. He possesses almost all the characteristics of resolution cards.
