    Abstract: An image processing apparatus able to instantaneously transmit image data on which a color/monochrome judgment and a series of processings have been performed comprising: a color/monochrome judging device for judging if input RGB image data is color or monochrome; a color image correction processing unit for performing color image correction processing on the RGB image data and outputting color image data; a monochrome image conversion processing unit for performing monochrome image conversion processing on the RGB image data and converting the same to monochrome image data; image accumulation device for accumulating color image data and monochrome image data; a network I/F for transmitting the image data accumulated in the image accumulation device to an external network; and accumulation control device for outputting either the color image data or monochrome image data accumulated in the image accumulation device to an external network in accordance with the color/monochrome judgment result.

    Abstract: An image processing apparatus includes a spatial filtering unit which applies spatial filtering to input image data to generate filtered image data such that the spatial filtering provides a broader dynamic range for outputs than for inputs, and a high-resolution conversion unit which interpolates the filtered image data in a first direction by an average of values of two pixels adjacent in the first direction, in a second direction perpendicular to the first direction by an average of values of two pixels adjacent in the second direction, and in a direction diagonal to the first and second directions by an average of four pixels surrounding a pixel of interest, thereby converting the filtered image data into high-resolution image data.
