Input apparatus and method for acquiring a scan image

摘要

An input apparatus having a scan function according to the disclosure includes a position detecting unit to acquire position information of each unit image of a scan target object; a unit image acquiring unit to acquire each unit image by using the position information of each unit image; and an object image acquiring unit to acquire an object image of the scan target object by merging the acquired unit images.

主权项

1. An input apparatus, comprising:
a function input unit configured to receive a request for scanning; a scanning unit configured to acquire a scan image of a target object through a scan area according to the request for scanning; a position detecting unit configured to obtain information on a position of the scan image, wherein the position detecting unit includes a laser sensor and a gyro sensor, and wherein each of the laser sensor and the gyro sensor detects the information on the position of the scan image; a communication interface unit configured to transmit the scan image and the information on the position of the scan image to a display device; and a control unit configured to: compare position information of a latest scan image detected by the laser sensor with position information of a previous scan image detected by the laser sensor, which is detected just before the latest scan image, to obtain a comparison result, determine, based on the comparison result, whether the position information of the latest scan image is within an allowable range, wherein the allowable range represents a position range required for the input apparatus to normally acquire the scan image, determine position information detected by the gyro sensor as the position information of the scan image when the position information of the latest scan image is determined not to be within the allowable range, and determine position information detected by the laser sensor as the position information of the scan image when the position information of the latest scan image is determined to be within the allowable range.
