Image processing device and image processing method

An image processing device connected with an image reading device having a sensor to receive reflected light from a document, a component to perform image processing on data received from the sensor to acquire black-and-white image information, and a component to perform image processing on data received from the sensor to acquire color image information, the image processing device comprising:

• a component to transmit an instruction relating to the detection of a color code image in a black-and-white scan mode to the image reading device;
• a component to receive color image information for the detection of a color code image acquired by the component to acquire color image information from the image reading device based on the instruction;
• a component to determine whether or not to output black-and-white image information acquired by the component to acquire black-and-white image information to a printing device;
• and
• a component to analyze a code image in the document from the received color image information for a determination by the component to determine.

An image processing device connected with an image reading device having a black-and-white sensor and a color sensor that receive reflected light from a document, the image processing device comprising:

• a component that transmits an instruction relating to the detection of a color code image in a black-and-white scan mode to the image reading device;
• a component that receives information received via the black-and-white sensor and information received via the color sensor from the image reading device based on the instruction;
• and
• a component that analyzes a code image in the document from the information received via the color sensor.

An image processing device connected with an image reading device having a black-and-white sensor and a color sensor that receive reflected light from a document, the image processing device comprising:

• a component that transmits an instruction relating to the detection of a color code image in a black-and-white scan mode to the image reading device;
• a component that receives information the black-and-white sensor has received and information the color sensor has received, from the image reading device based on the instruction;
• a component that determines whether or not to cause a printing device to execute printing based on the received information the black-and-white sensor has received;
• and
• a component that analyzes a code image in the document using both the received information the black-and-white sensor has received and the received information the color sensor has received for a determination by the determining component.

An image reading device connected with an image processing device having a component that analyzes a code image in a document, the image reading device comprising:

• a sensor that receives reflected light from the document;
• a component that performs image processing on data received from the sensor to acquire black-and-white image information;
• a component that performs image processing on data received from the sensor to acquire color image information;
• and
• a component that receives an instruction relating to the detection of a color code image in a black-and-white scan mode from the image processing device, wherein
• when receiving the instruction from the receiving component, the component acquiring color image information acquires color image information for the detection of a color code image from the data received from the sensor, and transmits the acquired color image information for the detection of a color code image and black-and-white image information used in printing to the image processing device.
