US 6,148,117 A · Image processing system with alterable local convolution kernel

Abstract

A method for image processing combining a device-specific image processing kernel operation with a general image processing kernel operation. Device specific parameters are sent from a host computer to an imaging device. The imaging device selects appropriate device-specific convolution coefficients. The host computer selects additional kernel operations. In a first example embodiment, the device-specific coefficients are then uploaded to the host computer and the host computer convolves the host-specified operations with the device-specific operations. The combined kernel is then downloaded to the imaging device. In an alternative embodiment, the host-specified operations are downloaded to the imaging device for combining. The combined kernels are then used by the imaging device for convolution operations on an image. As a result, host computer software can modify a kernel operation within an imaging device with minimal knowledge of device-specific parameters such as native resolution.
