Abstract
An image reading apparatus includes 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, when the sensor detects the document is loaded on the image reading apparatus, and before a scan instruction is input to the image reading apparatus, control the image sensor to execute a pre-scan job with respect to the loaded document using a default set value.
Claims12
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.
An image reading method for an image reading apparatus, comprising:
- detecting whether a document is loaded on the image reading apparatus;
- executing a pre-scan job with respect to the document using a default set value when the document is detected to be loaded on the image reading apparatus, and before a scan is input to the image reading apparatus;
- and
- applying 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 an 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.
A non-transitory machine-readable storage medium encoded with instructions, that when executed, cause an image reading apparatus to:
- detect whether a document is loaded on the image reading apparatus;
- control an image sensor to execute a pre-scan job with respect to the document using a default set value when the document is detected to be loaded on the image reading apparatus, and before a scan instruction is 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.
