Anamorphic three-perforation imaging system
View Patent ↗An anamorphic imaging system is disclosed which maximizes the use of available image area to minimize display magnification and image degradation due to display magnification, reduces the amount of anamorphic squeeze during photography to lower image degradation due to anamorphosis, and in film applications, utilizes a film frame that is only three perforations in height to reduce the amount of original film needed. The frame for either film or digital applications has an aspect ratio of approximately 16:9, is contained within the total available frame area of a three-perforation frame or digital imager, and is sized to maximize image area. In preferred embodiments, the image capture area is approximately 0.900 inches wide by approximately 0.506 inches tall.
1. A method for capturing an image during original photography when an image capture aspect ratio differs from a display aspect ratio such that an image quality of the image is maximized, comprising:
choosing an anamorphic ratio of a taking lens during original photography to be approximately the display aspect ratio divided by the image capture aspect ratio; and
capturing the image in a frame sized to utilize as much of a total available frame area as possible;
wherein the image capture aspect ratio is selected to be equivalent to a 16:9 aspect ratio of a digital imager.
2. The method as recited in claim 1 , the total available frame area having a height equivalent to not more than the height of three perforations in film having regular perforations on a left and right side of the film and a width equivalent to not more than a distance between the perforations on the left and right side of the film.
3. The method as recited in claim 2 , further comprising choosing the anamorphic ratio to be approximately 1.34:1.
4. The method as recited in claim 1 , further comprising selecting the anamorphic ratio and sizing the frame to provide an image capture area of approximately 0.900 inches wide by approximately 0.506 inches tall.
5. A method for generating a release print image from images captured according to the method of claim 1 , the method comprising:
vertically stretching the image utilizing digital processing techniques to produce an intermediate image; and
resampling the intermediate image both horizontally and vertically using digital processing techniques to generate the release print image.
6. The method as recited in claim 5 , further comprising:
stretching the image by about 49% in a vertical direction; and
resampling the intermediate image by about 9.3% in both the horizontal and vertical directions.
7. A method for generating a release print image from images captured according to the method of claim 1 , the method comprising:
squeezing the image in the horizontal direction utilizing digital processing techniques to produce an intermediate image; and
resampling the intermediate image both horizontally and vertically using digital processing techniques to generate the release print image.
8. The method as recited in claim 7 , further comprising:
squeezing the image by about 49% in the horizontal direction; and
resampling the intermediate image by about 36.4% in both the horizontal and vertical directions.
9. An anamorphic imaging system for capturing an image, comprising:
an anamorphic lens for horizontally squeezing the image into an image capture area that fits within a total available frame area;
wherein the anamorphic lens has a horizontal squeeze ratio chosen to maximize the image capture area and image quality by utilizing as much of a width of the total available frame area possible while maintaining an aspect ratio of about 16:9.
10. The anamorphic imaging system as recited in claim 9 , the total available frame area having a height equivalent to not more than the height of three perforations in film having regular perforations on a left and right side of the film and a width equivalent to not more than a distance between the perforations on the left and right side of the film.
11. The anamorphic imaging system as recited in claim 9 , wherein the anamorphic lens has a horizontal squeeze of approximately 1.34:1.
12. The anamorphic imaging system as recited in claim 9 , wherein the anamorphic lens has a horizontal squeeze selected to enable the image capture area to fit within the dimensions of a digital imager.
13. The anamorphic imaging system as recited in claim 9 , further comprising:
a digital image processor programmed for vertically stretching the captured image to produce an intermediate image, and resampling the intermediate image both horizontally and vertically to generate a release print image.
14. The anamorphic imaging system as recited in claim 13 , the digital image processor further programmed for stretching the image by about 49% in the vertical direction, and resampling the intermediate image in both the horizontal and vertical directions.
15. The anamorphic imaging system as recited in claim 9 , further comprising:
a digital image processor programmed for horizontally squeezing the captured image to produce an intermediate image, and resampling the intermediate image both horizontally and vertically to generate a release print image.
16. The anamorphic imaging system as recited in claim 15 , the digital image processor further programmed for squeezing the image by about 49% in the horizontal direction, and resampling the intermediate image in the both the horizontal and vertical directions.
