Learn moreDetermining the lowest light level at which a camera still delivers acceptable image quality requires well‑defined tolerance thresholds for all relevant factors. This paper presents a psychophysical study comparing expert and non‑expert evaluations across photographic and security‑camera use cases to establish application‑specific acceptance limits. The results provide a foundation for understanding how image quality degrades as light decreases and where compensation mechanisms reach their limits.
Learn moreISO第42技术委员会（摄影）下属多个工作组的成员已开始着手探讨一个重要议题，即为各种摄影应用中的图像质量测试提供关于应使用何种肤色的指导。

Learn moreMachine‑vision systems rely on accurate sensor characterization, yet the EMVA 1288 standard’s use of monochrome illumination raises important questions about real‑world comparability. This study examines how different light sources influence key measurement results and shows that only quantum efficiency and related parameters are affected. Using broadband illumination can therefore offer more practical insight into application‑specific performance.

Learn moreDiffractive‑optics–based geometric camera calibration has opened the door to highly compact, easy‑to‑use setups capable of capturing precise dot‑grid patterns from virtual infinity. This paper explores the method’s untapped potential, from extreme wide‑FOV calibration to large entrance pupils and automotive distances, while addressing key limitations such as infinity‑only measurement and chromatic constraints. Several practical solutions are presented to extend the technique beyond distortion measurement toward richer system characterization.
