F-stop weighted waveform with picture monitor markers
View Patent ↗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.
1. 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.
2. The method of generating a display according to claim 1 , in which the width of the first range of f-stops is adjustable by a user.
3. The method of generating a display according to claim 1 , in which the center of the first range of f-stops is adjustable by the user.
4. The method of generating a display according to claim 1 , in which modifying the original image by modifying original pixels comprises replacing at least some of the original pixels that fall within the first range of f-stops with a colored pixel.
5. The method of generating a display according to claim 1 , in which modifying the original image by modifying original pixels comprises combining brightness values of at least some of the original pixels that fall within the first range of f-stops with a color value.
6. The method of generating a display according to claim 1 , further comprising:
selecting f-stop equivalents that fall within a second range of f-stops;
modifying the original image by modifying original pixels that fall within the second range of f-stops to produce the modified image, in which modifying original pixels that fall within the second range of f-stops is different than modifying original pixels that fall within the first range of f-stops.
7. The method of generating a display according to claim 6 , in which modifying original pixels that fall within the first range of f-stops comprises modifying the original pixels by applying a first color and in which modifying original pixels that fall within the second range of f-stops comprises applying a second color.
8. 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.
9. The method of generating a display according to claim 8 , in which false coloring portions of the original image comprises replacing at least some of the original pixels that fall within a first range of f-stops with a colored pixel.
10. The method of generating a display according to claim 8 , in which false coloring portions of the original image comprises combining at least some of the original pixels that fall within a first range of f-stops with a colored pixel.
11. 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.
12. The waveform monitor of claim 11 , in which the modifier is structured to replace the selected pixels with a colored pixel.
13. The waveform monitor of claim 11 , in which the modifier is structured to combine the selected pixels with a colored pixel.
14. The waveform monitor of claim 11 in which the selector is user controllable.
15. The waveform monitor of claim 11 in which the selector is further structured to create a second range of f-stop values.
16. The waveform monitor of claim 15 , in which the modifier is further structured to change the original image for selected pixels that fall within the second range of f-stop values.
17. The waveform monitor of claim 11 , further comprising an output generator structure to generate an f-stop vs. time waveform.
18. The waveform monitor of claim 11 , in which the converter structured to generate f-stop comprises a Look Up Table (LUT).
19. The waveform monitor of claim 18 , in which the LUT is one of a plurality of previously stored LUTs accessible by the waveform monitor.
