Image Enhancement

We also offer a professional post scan image processing service to digitally enhance and optimise drawings that have been scanned from aperture card microfilms. Our advanced image processing software is used to crop, deskew and remove dark shadows or unfocused parts of the image to ensure the highest quality output. Here’s how our service works:

First, we scan the aperture card films using our industrial high-resolution scanners to achieve the best image quality. Then, we import the scanned images into our image processing software, where we can crop the image to remove unnecessary borders and edges, and focus on the drawing itself.

Next, we deskew the image to straighten any lines or curves that may be off-center. We use our software to adjust the brightness, contrast, and exposure to remove any dark shadows and improve the overall image quality. We can also sharpen and apply noise reduction tools to selectively enhance the focused parts of the drawing while minimising the impact of any unfocused areas.

The above image processing work can be carried out on individual drawings or batch of drawings, using both manual or fully automated method, depending on our client’s requirements.

Once the image has been cropped, deskewed, and optimised, we save it as a high-resolution file in a format such as TIFF or PDF, ensuring easy access and future reference or sharing. Our professional service helps to enhance and optimise drawings scanned from aperture card films, making them clearer and easier to read, while preserving their historical significance.

FAQs - Aperture Card Scanning and Conversion to Digital Format

An aperture card is a type of punched card that contains a cut-out or aperture for holding 35mm microfilm. These cards were commonly used to store engineering drawings, architectural plans, and other types of technical documents in the pre-digital era. The microfilm on the card can be viewed and printed using a microfilm reader or scanner. Although aperture cards are less commonly used today, they are still encountered in certain industries and archives.

The aperture card scanning process involves feed & aligning the aperture card correctly in the scanner by using either manual and automated feeder (depending on the condition and the original storage format of the cards), adjusting the scanner settings, scanning the image using a high-resolution camera, and reviewing the image for quality assurance. Once scanned, the digital image can be saved in various file formats such TIFF and PDF and securely delivered to the client.
