Abstract
At the time of registration, an image processing apparatus registers color information (R, G, B) from a host computer as permanently registered information in a buffer and as temporarily registered information in a table in accordance with a command from the host computer. The data registered in the buffer also is registered in the table and is used as internal data until initialization is performed. At the time of initialization, the data registered in the table is initialized with the exception of the data that has been registered from the buffer, if the command is indicative of a soft reset. In case of a hard reset, all of the data in the table is initialized.
Claims38
An image processing apparatus comprising:
- receiving means for receiving a plurality of color component data represented by a plurality of color codes and a command relating to storing the data;
- and
- memory means for storing the data in accordance with said command,
- wherein said memory means is capable of storing data represented by a plurality of the color codes, and said command relates to storing a part of the plurality of color codes.
An image processing apparatus comprising:
- memory means for storing a plurality of color component data represented by a plurality of input color codes with registration level data;
- and
- control means for cancelling the data in accordance with the registration level data,
- wherein said control means cancels a part of the data represented by a part of the plurality of input color codes in accordance with the registration level data.
An image processing method comprising the steps of:
- inputting a command which commands rewriting of data stored in a memory means;
- discriminating whether data of a plurality of color components stored in the memory means should be rewritten or not, the data of color components corresponding to a color code;
- and
- rewriting data of a plurality of color components stored in the memory means in accordance with the discrimination result,
- wherein the discrimination is performed code by code in accordance with the command.
An image processing apparatus having a function for registering data at least at first and second registration destinations, comprising:
- first input means for inputting, at the time of registration, data accompanied by registration information which indicates one of said first and second registration destinations;
- first registration means for registering the data, inputted by said first input means, in said first or second registration destination in accordance with the registration information accompanying this data;
- second registration means for registering data, which has been registered at said first registration destination by said first registration means, also in said second registration destination;
- second input means for inputting an initializing command, which indicates one of at least first and second initializing methods, at initialization of the data registered by the second registration means;
- total initializing means for initializing all of the data registered by said second registration means in a case where the initializing command inputted by said second input means corresponds to the first initializing method;
- and
- partial initializing means for initializing only the data registered by said first registration means, among the data registered by said second registration means, in a case where the initializing command inputted by said second input means corresponds to the second initializing method.
A controller for receiving code data and outputting print data to a printer, said controller comprising:
- receiving means for receiving a plurality of kinds of a reset command from an external device;
- and
- processing means for performing data processing in accordance with the kind of reset command which is received.
An image processing apparatus comprising:
- memory means for storing a plurality of color component data represented by a plurality of color codes;
- and
- controlling means for resetting the plurality of color component data, and subsequently setting predetermined default data of the plurality of color component data,
- wherein said controlling means resets a part of the data represented by the plurality of color codes and subsequently sets the predetermined default data.
