Image processing apparatus and method

An image processing apparatus comprising:

• an overwriting unit that overwrites a partial image data of an image and
• a partial image data storing unit that stores the output partial image data from the overwriting unit;
• a process prediction unit that predicts whether further overwriting is performed upon the partial image data;
• a completion judgment unit that sends the partial image data to a coding unit if the overwriting processing is complete, and to a data storing unit otherwise, the coding unit performing a predetermined image data compression coding upon the partial image data;
• a data storing unit that stores either the partial image data output from the completion judgment unit or the code data output from the coding unit;
• an output switching unit that sends the data stored in the data storing unit to the overwriting processing unit if it is a partial image data, and to a code data converting unit if it is a code data, the code data converting unit converting the code data so as to further reduce its code quantity;
• and
• a code data output unit that outputs the resulting code data from the code data converting unit.

An image processing apparatus comprising:

• an overwriting unit that overwrites a partial image data of an image data;
• a partial image data storing unit that stores output partial image data from the overwriting unit;
• a first data storing unit different from the partial image data storing unit that stores the output partial image data received from the partial image data storing unit;
• a coding unit that performs a predetermined image data compression coding upon the output partial image data to generate code data;
• a second data storing unit that stores the code data;
• and
• a decoding unit that decodes the code data by an inverse process of the predetermined image data compression coding, wherein the overwriting unit reads the partial image data of the image data from the first data storing unit to overwrite the partial image data of the image data, and wherein the decoding unit decodes the code data when the overwriting unit completes the overwriting.

• a partial image data storing unit that stores output partial image data from the overwriting unit;
• a first data storing unit different from the partial image data storing unit that stores the output partial image data received from the partial image data storing unit;
• a coding unit that performs a predetermined image data compression coding upon the output partial image data to generate code data;
• a second data storing unit that stores the code data;
• a code data converting unit that converts the code data so as to further reduce its code quantity;
• and
• a code data output unit that outputs the code data, wherein the overwriting unit reads the partial image data of the image data from the first data storing unit to overwrite the partial image data of the image data.

An image processing method comprising the steps of:

• overwriting a partial image data of an input image data and a partial image data of an image data of which the overwriting processing is not complete;
• predicting whether further overwriting is performed upon the partial image data;
• generating a code data by performing a predetermined image compression coding upon the partial image data of which the overwriting is complete;
• storing the partial image or code data;
• and
• decoding the code data by an inverse process of the predetermined image compression coding, wherein a judgment of whether the overwriting process is complete or not complete is based on the predicting of whether further overwriting is performed upon the partial image data.

An image processing apparatus that sequentially overwrites an image data with another image data comprising;

• an image data storing unit that stores an image data being overwritten;
• an image data input unit that inputs a partial image data;
• an overwriting processing unit that partially overwrites the image data stored in the image data storing unit with the input partial image data;
• a predicting unit that predicts whether further overwriting is performed;
• and
• a controlling unit that stores in the image data storing unit the overwritten partial image data that is predicted to have a further overwriting processing without coding, and after coding otherwise, wherein the overwriting processing unit reads from the image data stored in the image data storing unit to partially overwrite the image data stored in the image data storing unit with the input partial image data.

An image processing apparatus that sequentially overwrites an image data with another image data comprising:

• an image input unit that inputs a partial image data;
• a first image data storing unit that stores a non-coded image data being overwritten;
• a second image data storing unit that stores a coded image data being overwritten;
• an overwriting processing unit that partially overwrites the non-coded image data stored in the first image data storing unit with the partial image data;
• a first control unit that stores the non-coded overwritten image data in the first image data storing unit;
• and
• a second control unit that stores the coded image data being overwritten in the second image data storing unit, wherein the overwriting processing unit reads from the non-coded image data stored in the first image data storing unit to partially overwrite the non-coded image data stored in the first image data storing unit with the partial image data.
