Imatest Ultra-Wide Field of View Test Fixture 한 장의 차트로는 pre-distorted 차트(광각 렌즈의 왜곡을 대비하여 pin-cushion처리)를 활용하여도 160도 이상의 FOV에 대응하지 못합니다. 이 경우 e-sfr ISO center차트와 SFR reg차트(모서리 차트)와의 조합을 통해서만 정확한 평가가 가능합니다. 하지만 평가 환경 구축과 신뢰성 있는 세팅의 재현은 쉽지 않은 일입니다.(조명, 차트 위치 고정 등) 이에 이마테스트에서는 차트와 조명, 기구물을 포함한 평가 시스템을 도입하였습니다.
SFRplus Chart: Inkjet on Paper - 4:1 Contrast Ratio The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including: Much less wasted area The ability to produce a map of sharpness over the sensor surface Better measurement accuracy due to the lower contrast Full support for automated testing
SFRplus Chart: Inkjet on Paper - 10:1 & 2:1 Contrast Ratio The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, tonal response, and color accuracy. The SFRplus module features fully automated region-of-interest detection. The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including 1) much less wasted area, 2) the ability to produce a map of sharpness over the sensor surface, 3) better measurement accuracy due to the lower contrast, and 4) full support for automated testing.
SFRplus Test Charts on Color High-Precision LVT Film These charts are produced with a high-precision LVT film recording process for the best possible density range, low noise, and fine detail. We have multiple options available including Small (Half Sheet), Medium (Full Sheet), and Multi-Size (Full Sheet) targets.
SFRplus Large LVT Film Chart This chart has an active chart area of 48.3 cm x 26.81 cm (19 in x 10.56 in) in a total film size of 30.48 cm x 50.8 cm (12 in x 20 in). Bar-to-bar height is 252 mm (9.92 in).
SFRreg Test Chart Distortion Note: High amounts of distortion where the target may be compressed so that the major axis is 50% larger than the minor axis may have issues with autodetection. Pre-distortion for may be necessary for these cases.
Checkerboard Test Chart The Checkerboard Test Chart is available on matte inkjet, film, and chrome-on-glass substrates. It is designed to work with the Checkerboard module. This module enhances testing of varying distances by supplying more testable regions to provide automated measurements of sharpness, lateral chromatic aberration, and distortion from images.
Autofocus Scale Invariant This test chart is useful to measure auto focus consistency of a Digital Still Camera. The test chart covers all available camera devices and types of focuses to test. The slanted edges are formed by dark and light gray triangles to find the Spatial Frequency Response (SFR) from a series of images captured at several distances.
