Abstract
An image transmission apparatus indicating a color type of the color signal transmitted includes circuitry for separating color image information into a plurality of color signals and transmitting the plurality of color signals. An indication device is provided for, in response to the transmission of the plurality of color signals from the transmitting circuitry, indicating which of the plurality of color signals is transmitted. The indication may include an indication of one of a R G or B signal or an indication of a monochromatic or multi-chromatic transmission.
Claims27
An image transmission apparatus comprising:
- a) means for separating color image information into a plurality of color signals;
- b) means for supplying to a monitor the plurality of color signals separated by said separating means;
- c) means for transmitting the color image information in units of color signals in one of two transmission modes comprising (i) a monochrome transmission mode for transmitting luminance data which are combined with said plurality of color signals and (ii) a color transmission mode;
- and
- d) display means for displaying which of the plurality of color signals separated by said separating means is supplied to the monitor by said supplying means, and for displaying either the monochrome transmission mode or the color transmission mode.
A processing system comprising:
- a) means for separating color image information into a plurality of color signals and capable of transmitting the plurality of color signals in one of two transmission modes comprising a monochrome transmission mode for transmitting luminance data which are combined with said plurality of color signals and a color transmission mode, said separating and transmitting means for transmission of the plurality of color signals through a transmission line;
- and
- b) display means for displaying either the monochrome transmission mode or the color transmission mode transmitted by said transmitting means.
A processing system comprising:
- a) means for separating color image information into a plurality of color signals;
- b) means for supplying to a monitor the plurality of color signals separated by said separating means;
- d) means for transmitting the color image information in units of color signals, said transmitting means adapted for transmitting the color image information in one of two transmission modes comprising (i) a monochrome transmission mode for transmitting luminance data which are combined with said plurality of color signals and (ii) a color transmission mode, through a transmission line;
- and
- d) display means for displaying (i) a color kind of the color signal supplied by said supplying means to the monitor and (ii) the monochrome transmission mode or the color transmission mode.
A method of transmitting a color image to a communication line which has a transmission rate, comprising the steps of:
- a) storing color image data in a memory using at least one color component;
- and
- b) converting the stored color image data into monochrome data while reading out the stored color image data from said memory at a rate associated with the transmission rate of the communication line.
