An image interface circuit for compressing an image for subsequent transmission via a radio transmission channel, comprising; an image reception port; an image reception circuit for receiving an image from said image reception port in a first compressed signal format; an image decompression circuit for decompressing said first compressed signal format; an image segmenting circuit for segmenting the image into text and non-text areas; an optical character recogniser for recognising text characters in the text areas and generating corresponding character data; an image encoder circuit for compression-encoding the non-text areas into a image data in a second image signal format different to said first image format; a compressed image transmission port connected to said radio transmission channel, and; a signal combiner circuit for combining the character data and the image data into a combined signal and supplying the combined signal to the compressed image transmission port. <IMAGE> |
