Abstract
A digital camera includes a processor having an algorithm for comparing a set of resolution pixel values in a generated image file with corresponding ones of resolution pixel values in a user selected file and for providing as a final digital zoom image resolution the set of resolution pixel values in the generated image file when the corresponding ones of the resolution pixel values in the user selected file are at least equal but not less than the corresponding resolution pixel values in the generated image file, and a scaled down set of resolution pixel values when the corresponding ones of the resolution pixel values in the user selected file are less than the corresponding resolution pixel values in the generated image file.
Claims18
A method of maximizing image resolution in a digital camera, comprising:
- applying a user selected digital zoom factor Zf to a highest available image resolution value to obtain a maximum image file size;
- applying a user selected image file size to a digitally zoomed image when said maximum image file size is at least equal to but not greater than said user selected image file size;
- and
- applying a resized image file size to said digitally zoom image when said maximum image file size is greater than said user selected image file size, wherein said resized image file size is scaled down file size.
A method of maximizing image resolution in a digital camera, comprising:
- applying a user selected digital zoom factor Zf to a highest available image resolution value of Nmax pixels by Mmax pixels to obtain a maximum image file size of Nmax/Zf pixels by Mmax/Zf pixels;
- applying a user selected image file size of Nsn pixels by Mrn pixels to a Zf digitally zoomed image when said maximum image file size is at least equal to but not greater than said user selected image file size;
- and
- applying a resized image file size to said Zf digitally zoom image when said maximum image file size is greater than said user selected image file size, wherein said resized image file size is scaled down file size.
A digital camera, comprising:
- means for applying a user selected digital zoom factor Zf to a highest available image resolution value to obtain a maximum image file size;
- means for applying a user selected image file size to a digitally zoomed image when said maximum image file size is at least equal to but not greater than said user selected image file size;
- and
- means for applying a resized image file size to said digitally zoom image when said maximum image file size is greater than said user selected image file size, wherein said resized image file size is scaled down file size.
A method of providing a final digital zoom image resolution, comprising:
- comparing a set of resolution pixel values in a generated image file with corresponding ones of resolution pixel values in a user selected file;
- providing as the final digital zoom image resolution said set of resolution pixel values in the generated image file when the corresponding ones of the resolution pixel values in the user selected file are at least equal but not less than the corresponding resolution pixel values in said generated image file;
- and
- providing as the final digital zoom image resolution a scaled down set of resolution pixel values when the corresponding ones of the resolution pixel values in the user selected file are less than the corresponding resolution pixel values in said generated image file.
A digital camera, comprising:
- a processor having an algorithm for comparing a set of resolution pixel values in a generated image file with corresponding ones of resolution pixel values in a user selected file and for providing as a final digital zoom image resolution:
- said set of resolution pixel values in the generated image file when the corresponding ones of the resolution pixel values in the user selected file are at least equal but not less than the corresponding resolution pixel values in said generated image file, and a scaled down set of resolution pixel values when the corresponding ones of the resolution pixel values in the user selected file are less than the corresponding resolution pixel values in said generated image file.
A digital camera, comprising:
- a modifier circuit for applying a user selected digital zoom factor Zf to a highest available camera image resolution value to obtain a maximum image file size;
- and
- a comparison circuit for applying a user selected image file size to a digitally zoomed image when said maximum image file size is at least equal to but not greater than said user selected image file size, and for applying a resized image file size to said digitally zoom image when said maximum image file size is greater than said user selected image file size, wherein said resized image file size is scaled down file size.
