Abstract
An image information processing apparatus of this invention receives an information signal, converts the input information signal into digital data, temporarily stores the converted digital data, parallel/serial-converts the temporarily stored digital data, and controls the operation of the parallel/serial processing in accordance with the contents of information indicated by the temporarily stored digital data when the parallel/serial-converted digital data is converted into an analog signal and the analog signal is transmitted onto the transmission path, thereby allowing easy transmission of image information and a control code using a smaller number of transmission path and realizing a cost reduction.
Claims12
An image processing apparatus comprising:
- (A) divisional output means for receiving digital image data, dividing the input digital image data in units of a predetermined number of bits, and outputting the divided data;
- (B) data conversion means for receiving the data each having the predetermined number of bits output from said divisional output means, and outputting conversion data corresponding to the input data;
- (C) digital/analog conversion means for converting the conversion data output from said data conversion means into an analog signal, and outputting the analog signal;
- (D) analog signal transmission means for transmitting the analog signal output from said digital/analog conversion means via a transmission path;
- (E) receptions means for receiving the analog signal transmitted from said analog signal transmission means via the transmission path;
- (F) analog/digital conversion means for converting the analog signal received by said reception means into digital data, and outputting the digital data;
- and
- (G) data inverse conversion means for receiving the digital data output from said analog/digital conversion means, and outputting the data before conversion in said data conversion means corresponding to the input digital data.
An image processing method comprising the steps of:
- (A) receiving input digital image data;
- (B) dividing the input digital image data into data each having a predetermined number of bits;
- (C) outputting the divided data;
- (D) receiving the output data each having the predetermined number of bits;
- (E) outputting conversion data corresponding to the received data;
- (F) converting the conversion data into an analog signal, and outputting the analog signal;
- (G) transmitting the analog signal via a transmission path;
- (H) receiving the analog signal transmitted via the transmission path;
- (I) converting the analog signal into digital data, and outputting the digital data;
- and
- (J) receiving the digital data and outputting said divided data.
