Abstract
A scanner has a first sensor array; a second sensor array; a timing controller that individually outputs at different times a first drive signal that drives the first sensor array, and a second drive signal that the second sensor array; and a light source configured that emits and illuminates a document during periods between the first drive signal and the second drive signal output next after the first drive signal, and periods between the second drive signal and the first drive signal output next after the second drive signal.
Claims7
A scanner comprising:
- a first sensor array including multiple first sensors arrayed in a main scanning direction;
- a second sensor array, including multiple second sensors arrayed in the main scanning direction, disposed offset in a sub-scanning direction from the first sensor array;
- a timing controller configured to cyclically output, at different times, to the first sensor array and second sensor array, a first drive signal that drives the multiple first sensors of the first sensor array, and a second drive signal that drives the multiple second sensors of the second sensor array;
- and
- a light source configured to emit and illuminate a document during periods between the first drive signal and the second drive signal output next after the first drive signal, and periods between the second drive signal and the first drive signal output next after the second drive signal.
A method of producing a scanned image using a scanner having a first sensor array including multiple first sensors arrayed in a main scanning direction,
- a second sensor array, including multiple second sensors arrayed in the main scanning direction, disposed offset in a sub-scanning direction from the first sensor array,
- a timing controller, and
- a light source,
- the scanned image production method comprising:
- multiple first sensors reading a document according to a first drive signal applied cyclically by the timing controller;
- multiple second sensors reading a document according to a second drive signal applied cyclically by the timing controller;
- the emitting and illuminating the document during periods between the first drive signal and the second drive signal output next after the first drive signal, and periods between the second drive signal and the first drive signal output next after the second drive signal;
- and
- generating a scanned image based on the read result of the multiple first sensors and the read result of the multiple second sensors.
