Image processing system

An image receiver device, comprising:

• a receiver unit that receives a series of data, including image data, via a communication path;
• an image processing unit configured to subject the input image data to a specified series of image processing;
• and
• a process controller that identifies details of pre-processing previously executed for the image data, if any, in response to a preset control signal included in the series of received data, and controls the specified series of image processing to be executed by said image processing unit, if any, based on a result of the identification,
• wherein said process controller prohibits said image processing unit from executing a series of image processing equivalent to the pre-processing.

An image transmitter device that transmits image data via a communication path to a plurality of image receiver devices connecting with the communication path, said image transmitter device comprising:

• a specification receiver unit that receives a specification of each image receiver device from each image receiver device of the plurality of image receiver devices;
• an image processing unit that specifies a series of image processing to be executed therein according to the input specification, and generates processed data from input master image data by the specified series of image processing;
• a control signal generator that generates a control signal for prohibiting a series of image processing to be executed by each image receiver device from including the specified series of image processing carried out by said image processing unit;
• and
• a transmitter unit that transmits said processed data and said control signal to said each image receiver device.

An image processing method in an image receiver device, said image processing method comprising:

• (a) determining requirements of image processing and, when required, specifying a series of image processing to be executed by said image receiver device, in response to a control signal mapped to image data received via a communication path;
• and
• (b) making the input image data subjected to the specified series of image processing based on a result of the determination in said step (a), and outputting a resulting image,
• wherein said control signal prohibits said image receiver device from executing image processing equivalent to image processing previously applied to said image data.

A recording medium in which a program is recorded in a computer readable manner, said program controlling operations of an image receiver device, said program causing a computer to perform the functions of:

• determining requirements of image processing and, when required, specifying a series of image processing to be executed by said image receiver device, in response to a control signal mapped to image data received via a communication path;
• and
• making the input image data subjected to the specified series of image processing based on the determination,
• wherein said control signal prohibits said image receiver device from executing image processing equivalent to image processing previously applied to said image data.

An image transmitter device that transmits image data via a communication path to an image receiver device connected to the communication path and having an image processing function, said image transmitter device comprising:

• an image processing unit configured to generate processed data from input master image data by a specified series of image processing;
• a control signal generator configured to generate a control signal for prohibiting an image processing to be executed by said image receiver device from including the specified series of image processing carried out by said image processing unit;
• and
• a transmitter unit that transmits said processed data and said control signal to said image receiver device,
• wherein the specified series of image processing excludes compression.
