Abstract: An image is captured into a video signal comprised of individual pixels by means of an array sensor with color stripes. When processing the signal from the sensor, the system first interprets the highest frequencies of the signal as an upper sideband of the I color component in such a way that doubles the recoverable bandwidth of color detail. From the upper sideband of the signal, the corresponding lower color sideband is predicted and its effect is then subtracted from the luminance component, from which, in turn, an image is generated. The resulting image thereby produced is thus enhanced in sharpness while at the same time exhibiting a reduction in artifacts. Preferably color is demodulated from such a striped array sensor signal wherein the step is included of demodulating the predominant I color vector from the color carrier utilizing an asymmetric sideband filter.

Abstract: A system and method to compensate for effects of a recording medium such as film on image data retrieved therefrom. Red, green, blue, and infrared light is sequentially transmitted through film having an image exposed therein to the system which captures corresponding images. The infrared image maps the location, boundaries and intensities of the media defects. The map is employed combinatorially with the other captured images resulting in an image from the film free of the effects of the film defects. In one embodiment the effects of the imperfections are divided out from the red, green, blue spectra in an operation dividing out the infrared image data on a pixel-by-pixel basis. In an alternate embodiment wherein the imperfections substantially prevent transmission of IR light therethrough, the IR image map of the defects is nevertheless employed with an automated fill-in algorithm more effectively utilized due to the precision with which the defect boundaries are known.

Abstract: A mask having at least two areas is defined over an image. The mask pixels are mapped with, in the preferred embodiments, an error diffusion or dithering process to mix the mask pixels between the areas. Image pixels which correspond in position to the mask pixels are mapped to colour palettes selected for the at least two areas. An image effect is applied to the colour palette of one of the areas called the unmasked area. The same image effect is not applied to the masked area. The error diffusion or dithering has provided a fuzzy edge to the mask and these processes are quick to accomplish with a minimum number of states. Since the image effect is applied to only a relatively small number of palette colours, user feedback is nearly instantaneous.

Abstract: A method and apparatus for controlling and displaying the image information presently seen by the image capture device together with those images which have been captured and stored upon actuation of the device. In a preferred embodiment, a viewfinder window is located in a capture device window. The capture device window also includes a variety of push buttons, some of which control the image capture device, others of which control the way in which the captured images are displayed on the computer screen. In response to the user command to capture an image, the image will be displayed adjacent to the image capture window. As the user continues to capture images, the frames are displayed as long as the computer has adequate temporary storage. Means to discard some images are also included in the user interface. Preferably, the discarded images are retained to allow the maximum reversibility of decisions to the discard images. The user interface also allows the user to stack a set of images into a single object in the workspace. Images may be manipulated within the stack, discarded or modified or changed between stacks of image objects.
