    Abstract: Systems and methods are presented for generating a new digital output image by blending a plurality of digital input images capturing the same scene at different levels of exposure. Each new pixel for the new digital output image is derived from a group of corresponding aligned pixels from the digital input images. For each group of corresponding pixels from the digital input images, an average color value in a first color space is derived by taking a separate average across each color channel of the first color space. The resulting average color value in the first color space is modified in order to raise its corresponding color saturation value in a second color space. The new pixel's color value in the first color space is set to the modified average color value.

The major part of the panoramic HDR image method and system is a two-pass optimization-based approach that first defines the position of the objects in a scene and then fills in the dynamic range when possible and consistent. Data costs are created to encourage radiance values that are both consistent with object placement (defined by the first pass) and of a higher signal-to-noise ratio. Seam costs are used to ensure that transitions occur in regions of consistent radiances.

    Abstract: A method for image capture and estimation of range information is provided which uses photographic film as the image capture mechanism. A plurality of identical images are captured on film yielding an image bundle wherein each image in the image bundle is captured with a different phase offset. Fiducial marks are placed on the photographic film between adjacent images in the image bundle. The image bundle is developed and the developed images are scanned. The images of the image bundle are then registered by aligning the fiducial marks. The distance from the image capture device to object(s) in the images of the image bundle can then be estimated using the different phase offsets for each image. The range at a pixel location is estimated by selecting the intensity of the pixel at that location of each image and performing a best fit of a sine wave of one period through the points.
