Industry-specific Solutions [Security]

Industry-specific Solutions [Security]

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

The continuous development of camera technology is expanding the requirements for image technology in the security field. New features such as motion and facial recognition have been added as standard. The amount of data transferred continues to increase, and consequently, the quality of image materials is required to be high. This enables software-based evaluation systems. Security cameras must operate under various conditions, utilizing LED lights and other means, from direct sunlight to extremely low brightness levels. Since they must function under high contrast levels in direct sunlight, cameras need to have a high dynamic range, and it is optimal to use TE269C (compliant with IEC62676-5 video surveillance camera standards) in front of high-intensity flicker lighting devices like LG3. For resolution, optical parameters, and other specifications, you can use standard charts (TE253 9x, TE251) in combination with the image analysis software iQ-Analyzer-X.

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 [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.

Industry-Specific Solutions [Automotive / In-Vehicle]

Industry-Specific Solutions [Automotive / In-Vehicle]

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

In the field of in-vehicle camera imaging, customer demands are currently overwhelmingly focused on two quality parameters: high dynamic range combined with OECF and spatial resolution. Therefore, the recommended light sources for image quality evaluation in the automotive industry are the LE7, an illumination device for transmission charts equipped with iQ-LED (integrating sphere), or the LG3, a high-intensity flicker-free lighting device. The recommended charts are the OECF chart TE269B (measurable dynamic range of 1,000,000:1 / 120dB) or TE269C (measurable dynamic range of 5,000,000:1 / 134dB). Additionally, the reflective chart TE261 with an inclined edge of size A1066 allows for the measurement of SFR (spatial frequency response) even for cameras with a high level of geometric distortion. These quality parameters can be analyzed using the image analysis software iQ-Analyzer-X.

Industry-Specific Solutions [Medical / Endoscopy]

Industry-Specific Solutions [Medical / Endoscopy]

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

Most medical imaging applications are designed to capture images at a microscopic (or small) scale. Therefore, the test charts must also be small. To uniformly illuminate the final image with the same light source, we recommend the CAL4 integrating sphere with a diameter of 30 cm, which comes with four types of connection adapters for various endoscope light sources. (Note: The CAL4 does not come equipped with light sources such as iQ-LED.) The opening of this integrating sphere features a 50x50 mm output window with a slot for a D35 size chart. For resolution measurement, a D35 size Siemens star TE253 9x (compliant with ISO standard 12233:2014) is recommended. For measuring OECF, dynamic range, noise, etc., a D35 size TE240 chart with 24 gray patches (compliant with ISO 21550) is recommended. For color evaluation, the transmissive Calibrite ColorChecker TE188 (D35 size) is recommended, and for visual assessment, the U.S. Air Force resolution chart TE250 for 35mm film (D35 size) is recommended.

Industry-Specific Solutions [Machine Vision]

Industry-Specific Solutions [Machine Vision]

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

For the various applications of cameras in industrial image processing, the necessary conditions for cameras change depending on the application. Image processing, which demonstrates a wide range of true capabilities, provides data to verify quality, identify parts, read codes, and optimize manufacturing processes, while also controlling machines. Recommended products for machine vision evaluation allow for testing of key quality criteria such as dynamic range, resolution, sensitivity, noise, and frame rate, including optical systems and sensors. In machine vision, lighting is usually controllable. Therefore, a normal contrast of 10,000:1 is sufficient for the OECF chart. However, since tone levels are used for automatic detection and evaluation of various elements in images, it is helpful to measure the OECF in as much detail as possible. For this reason, the iQ-LED equipped lighting device (integrating sphere) LE7 for transmission charts and the 36 gray patch chart TE269B are recommended. For color, resolution, distortion, and shading, standard charts (TE253 9x, TE230, TE251, TE255) can be analyzed using the image analysis software iQ-Analyzer-X.
