Image processing apparatus and image reading method

An image processing apparatus comprising:

• an invisible light source configured to emit invisible light to a subject;
• a visible light source configured to emit visible light to the subject;
• an invisible image reading sensor configured to read invisible reflection light reflected from the subject to acquire an invisible image, the invisible reflection light being a part of the invisible light emitted from the invisible light source;
• a visible image reading sensor configured to read visible reflection light reflected from the subject to acquire a visible image, the visible reflection light being a part of the visible light emitted from the visible light source;
• and
• circuitry configured to:
• restore information lost in the invisible image acquired by the invisible image reading sensor;
• determine information to be retained, as a restoration target, based on the invisible image and the visible image and output a determination result indicating the restoration target;
• and
• generate an output image in which the information lost in the invisible image is restored based on the determination result.

• and
• circuitry configured to restore information lost in the invisible image acquired by the invisible image reading sensor,
• wherein the visible image reading sensor includes three reading pixel rows of:
• a red pixel row sensitive to at least a red visible wavelength range;
• a green pixel row sensitive to at least a green visible wavelength range;
• and
• a blue pixel row sensitive to at least a blue visible wavelength range, and
• wherein the invisible image reading sensor is configured to use a range of at least a portion of the red pixel row, the green pixel row, and the blue pixel row, the range being sensitive to an invisible light wavelength.
