Industry-specific solutions are the optimal solutions for starting quality tests tailored to the needs and requests of users.

There is no reliable method to measure dynamic range without the use of a transmission chart. Image Engineering offers the TE264, which measures noise, OECF, dynamic range, and ISO speed (in accordance with ISO standards 14524, 15739, and 12232). Transmission charts require uniform lighting, and for this purpose, the iQ-LED equipped transmission chart lighting device (integrating sphere) LE7 is an excellent choice. By illuminating the TE264 with an integrating sphere equipped with an iQ-LED light source, you can achieve a highly uniform light source for measuring brightness, color, and shading (in accordance with ISO standard 17957) along with the TE255. For reflection charts, TE230 (Calibrite ColorChecker SG) is used for color reproduction, TE251 (in accordance with ISO standard 17850) for distortion and lateral chromatic aberration, and TE253 9x (in accordance with ISO standard 12233:2014) for resolution. For evaluating all images captured with the sample camera, the image analysis software iQ-Analyzer-X is recommended.

Industry-Specific Solutions [Scanner]

Industry-specific solutions are the optimal solutions for starting quality tests tailored to the needs and requests of users.

The image quality of scanners and cameras is typically tested using a chart that is one step superior to the expected test results of the scanner. The TE240, which measures dynamic range in accordance with ISO standard 21550, is prepared with both transmission and reflection charts. In the case of reflection, the highest contrast is limited to approximately 2.4 density. For transmission, users can choose a density between 4.0 and 6.0. The IT8 color target (TE258) is the standard chart for color profile creation. Image Engineering offers both reflection and transmission charts with wide color gamut. The U.S. Air Force resolution chart TE250 (transmission) is used for visual resolution analysis. Resolution measurement of scanners in accordance with ISO standard 16067 is traditionally conducted using the inclined edge target QA-62. This chart is currently available only in reflection.

Industry-specific solutions [Mobile phones and smartphones]

Industry-specific solutions [Mobile phones and smartphones]

Industry-specific solutions are the optimal solutions for starting quality tests tailored to the needs and requests of users.

Testing cameras that cannot be manually adjusted to match lighting conditions is always a challenge, especially for mobile phone camera modules such as those found in smartphones. The recommended product for evaluating mobile phone and smartphone image quality includes the multipurpose chart TE42. This chart allows for the assessment of various image quality performance metrics such as resolution, distortion, color (color reproduction), and texture loss, all in a single image. To conduct OECF and noise measurements in accordance with ISO standards 14524 and 15739, the TE270X is uniformly illuminated using the iQ-LED equipped lighting device (integrating sphere) LE7. This special chart is equipped with two polarizing filters at its center to facilitate automatic exposure control. By replacing the chart with the TE255 diffuser plate, it can be used to measure color and shading, which are particularly problematic for small camera modules. The captured images are evaluated using the image analysis software iQ-Analyzer-X.
