1. An image reading apparatus, comprising:
an image sensor to read a document;
a sensor to detect whether the document is loaded on the image reading apparatus; and
a processor to: control the image sensor to execute a pre-scan job with respect to the document using a default set value in response to detection of the document loaded on the image reading apparatus by the sensor prior to receiving a scan instruction input to the image reading apparatus; and
apply an option value in response to receiving a scan instruction during the pre-scan job to generate an image-processed scan image with respect to a remaining portion of the document not read by the image sensor in the pre-scan job, when the option value is different than the default set value of the pre-scan job, wherein the image-processed scan image is generated in parallel with the execution of an image processing operation of the scan image generated by the pre-scan job.
