Image processing device and image processing system using look-up table with exclusive or operation applied

An image processing device comprising:

• a memory device comprising a first look-up table, a second look-up table, and a third look-up table, the third look-up table including a plurality of pieces of data obtained based on performing an exclusive OR (XOR) operation on a plurality of pieces of data in the first look-up table and a plurality of pieces of data in the second look-up table;
• a first processor and a second processor, the first processor and the second processor configured to output a plurality of predetermined color values based on a plurality of input color values using at least a portion of the first look-up table, the second look-up table, and the third look-up table;
• and
• a control logic circuit configured to control the memory device,
• wherein based on receiving a read request for the first look-up table from each processor of the first processor and the second processor, the control logic circuit is configured to:
• transmit data stored in the first look-up table to the first processor;
• and
• transmit, to the second processor, data that is obtained based on performing an XOR operation on data stored in the third look-up table and data stored in the second look-up table.

An image processing system comprising:

• a display panel;
• a first memory comprising a first look-up table, a second memory comprising a second look-up table, and a third memory comprising a third look-up table;
• a first processor and a second processor, the first processor and the second processor configured to convert a plurality of input color values into a plurality of predetermined color values using at least one of the first look-up table, the second look-up table, or the third look-up table;
• and
• a control logic circuit configured to control at least a portion of the first memory, the second memory, and the third memory,
• wherein
• the third look-up table includes data obtained based on performing an exclusive OR (XOR) operation on a plurality of pieces of data in the first look-up table and a plurality of pieces of data in the second look-up table,
• based on receiving a read request for the first memory from each processor of the first processor and the second processor, the control logic circuit is configured to:
• transmit data stored in the first look-up table to the first processor;
• and
• transmit, to the second processor, data that is obtained based on performing an XOR operation on data stored in the third look-up table and data stored in the second look-up table, and
• the first processor and the second processor are configured to output the plurality of predetermined color values through different regions in the display panel.
