Calculate an Image Sensor Resolution Spacing (Pixel Size)
Enter the height and width of the image sensor, number of columns and rows
- Search Digital Photography Review for the camera manufacturer and model, select the specifications page and note the sensor size (0.1 - 1000.0 mm).
- If the sensor size is specified as 1/x.x" with standard 16mm conversion & 4:3 aspect ratio use the calculator below OR get the exact sensor height and width from the table in the Image Sensor Format article in Wikipedia.
- Enter the maximum resolution (100-100,000) in columns and rows (also available from Digital Photography Review).
- Enter the actual resolution (100-100,000) of the images in columns and rows if a lower sensor resolution is being used. In Windows, right click on the image file, select Properties and then Details.
- If the maximum and actual values are the same, leave the actual values blank.
Sensor Resolution Spacing (Pixel Size) Computation
- The maximum column and row counts on the sensor may be different to the image column and row resolution because of hidden or masked pixels.
- The actual column and row counts are smaller than the maximum counts, so the equivalent pixel size has to be larger on the same image sensor area.
- The computed pixel height and width may disagree due to different image aspect ratios (16:9 v 4:3) mapped to the image sensor.
