Abstract
A waveform monitor for generating a modified image from an original image includes a brightness measuring system to generate brightness values that are then converted to f-stop equivalents. A selector is used to create a range of f-stop values and a modifier changes the original image for selected pixels that fall within the range of f-stop values. The original image may be modified by replacing or blending certain pixels with colorized pixels, i.e., by falsely coloring the original image. Methods of modifying images in this manner are also described.
Claims19
A method of generating a display for output from a measurement instrument, the method comprising:
- receiving an original image formed of pixels;
- extracting brightness information from the pixels;
- converting the brightness information of the pixels to f-stop equivalents;
- selecting f-stop equivalents that fall within a first range of f-stops;
- modifying the original image by modifying original pixels that fall within the first range of f-stops to produce a modified image;
- and
- displaying the modified image.
A method of generating a display for output from a measurement instrument, the method comprising:
- receiving an original image formed of pixels;
- determining f-stop equivalents of the pixels;
- and
- false coloring portions of the original image based on the f-stop equivalents to generate a modified image;
- and
- displaying the modified image.
A waveform monitor having an image input and a monitor for viewing a measurement display, the waveform monitor comprising:
- a measuring system to measure brightness values for pixels from an original image received at the image input;
- a converter structured to generate f-stop values from the brightness values;
- a selector structured to create a range of f-stop values;
- and
- a modifier structured to change the original image for selected pixels that fall within the range of f-stop values.
