Abstract: A digital camera system providing processed audio signals, comprising: an image sensor for capturing a digital image; an optical system for forming an image of a scene onto the image sensor; a microphone for capturing an audio signal; a data processing system; a storage memory for storing captured images and audio signals; and a program memory communicatively connected to the data processing system and storing instructions configured to cause the data processing system to implement a method for providing processed audio signals, wherein the instructions include: capturing one or more digital images of a scene using the image sensor and capturing a corresponding audio signal using the microphone; determining a scene type corresponding to the captured digital images; processing the captured audio signal responsive to the determined scene type; and recording the captured digital images together with the processed audio signal in the storage memory.

Abstract: A method for automatically compensating for scanner metamerism errors associated with scanning input images using a digital color image scanner, wherein the input images can be on a variety of different input media having colorants with different spectral characteristics, comprising scanning an input image on a digital color image scanner to produce a scanned image; determining one or more estimated color balance error values in a color balance parameter space by analyzing the scanned image using a color balance analysis algorithm; assigning an input medium from a set of possible input media for the scanned input image in response to the estimated color balance error values; selecting a scanner metamerism correction color transform associated with the assigned input medium; and applying the selected scanner metamerism correction color transform to the scanned image to produce a corrected image compensated for scanner metamerism errors.

Abstract: Images are sharpened and corrected for position dependent blur by providing a sharpening function which is adapted to operate upon signals corresponding to a selected number of pixels, providing a plurality of values which are a function of the position dependent blur; and applying the plurality of values to the sharpening function to modify the sharpening function so that after the modified sharpening function is applied to the image, a sharpened image will be provided which has been corrected for the position dependent blur.
