Resolution Calculator
- Camera Resolution Rate (N)
- The pixels required to reliably reproduce a line pair. Optimum would be two pixels (one black and one white). No camera has this capability at this time. Through tests done by IFI, we find digitial cameras range from 3 to 4 and video cameras are typically 4 due to their low resolution.
- Prosumer cameras enter a "3".
- High-End Consumer cameras enter a "3.5".
- Video cameras enter a "4".
- Camera Type
- Is it a digital or video camera.
- Orientation
- Choose the longest dimension; width for horizontal (landscape) or height for vertical (portrait).
- Camera name
- Enter the name of the camera.
- Megapixel Rating
- If you don't know the width and height in pixels, enter the megapixel rating. This will be less accurate than entering width and height. (Width and height will automatically filled in.)
- Width in Pixels
- Enter the width in pixels of your camera's resolution. (Megapixel rating will automatically update.)
- Height in Pixels
- Enter the height in pixels of your camera's resolution. (Megapixel rating will automatically update.)
- Resolvable Details
- This section computes the smallest detail that can be reproduced from a scene area (column headers).
- Scene Width
- This section computes the maximum scene width that can reproduce the detail in the subject size (column headers).

DIRECTIONS TO OUR NEW BUILDING
The Indiana Forensic Institute (IFI) was established on the Indiana University Purdue University Indianapolis (IUPUI) campus in June, 1995 in response to an increased worldwide concern with crime. Citizens and criminal justice officials strongly expressed a need for operational and technological advances in their fight against crime. Advances in forensic imaging technology were often cited as an important component that would be useful for investigations and in the courtroom.
Starting in 2001, IFI, became an independent 501 (c)(3) cooperation, moved to an off-campus location and developed a strategic alliance with the Indiana University School of Informatics. Over the years, IFI has collaborated with the Naval Surface Warfare Center, Crane, Indiana, the Hudson Institute and several Criminal Justice agencies. IFI courses are certified by the Indiana Law Enforcement Academy.In the fall of 2008, IFI developed a close association with Wolf Technical Services, Inc., a forensic engineering company located in Indianapolis. Also, IFI, which teaches courses for the Purdue School of Science, and started a process to increase its portfolio from just imaging to a broad spectrum of forensic science disciplines. Accordingly, the name was changed from the Institute for Forensic Imaging to the Indiana Forensic Institute. Development of new offerings is now in progress.
The mission of The Indiana Forensic Institute is to help improve the effectiveness of the law-related investigations and trials through:
High-quality training and consulting which can expand and enhance investigators' capabilities assure more probative testimony in hearings and at trials.
Research and development activities, which lead to both publication of scholarly papers, books and manuals, as well as consultations and testing to improve the quality of practical devices
