An image processing apparatus and method for analyzing a digital image and automatically generating a visually attractive frame for the image. A data set for the image is analyzed, preferably in color space, to determine one or more image components representing dominant colors in the image. The components are characterized individually, and then these individual component characterizations are used to characterize the image overall. Based on the overall image characteristics, the framing scheme parameters are determined and used in turn to generate the attributes of a visually attractive frame for the image. A data set for the framed image is then generated, which may be sent to an imaging device for display or printing, or simply stored as a new data set for later use. The user has the ability to modify the rules that determine the framing scheme parameters so as to adjust the framed image if desired.

Automatic generation of frames for digital images

A system and method is described for automatically determining in a scanned document image the presence of unwanted extraneous information caused by an extraneous device and scanner background information. Once the presence of this information is determined, the system and method of the present invention can compute, for instance, skew and crop statistics. From this, the image can be automatically deskewed and cropped appropriately without the background and extraneous information. The system and method accomplishes this by first determining the presence of unwanted extraneous and background information and then appropriately processing the document image. The extraneous information is ignored during deskew and crop computations. Also, the scanner background and the extraneous information are prevented from being included in the final digital representation of the image.

Image processing system with automatic image cropping and skew correction

A digital camera includes a lens and a plurality of color filters adjacent the lens. An array of detectors such as CCDs each receive, through the lens and a corresponding one of the color filters, light reflected from a scene. Each detector outputs a signal representative of an amount of light it receives. Circuitry is connected to the array for processing the signals from the detectors and generating a set of digital image data including a chromaticity value and a luminance value of a plurality of pixels representing an uncorrected image of the scene. A control circuit maps a two-dimensional representation of the digital image data into a two-dimensional representation of a set of reference image data and adjusts selected ones of the values of the set of digital image data in accordance with a predetermined transform to white balance the uncorrected image of the scene and produce a modified set of digital image data representing a corrected image of the scene.
