Patent ID: 7929181

Claim:
A poor recording detection device for forming dots on a recording medium on the basis of input recording data by a recording head and detecting poor recording when recording, comprising: an illumination unit which applies illumination light to the recording medium after the recording; a camera unit which shoots and picks up an image recorded on the recording medium to which the illumination light is applied by the illumination unit and which outputs detected information; and a poor recording determination unit which outputs reference detection information obtained by detecting a reference recording image by the camera unit after inputting reference recording data as input recording data and recording the input recording data on the recording medium as the reference recording image, generates correction information by comparing the reference detection information with the reference recording data and generating corrected input recording data obtained by correcting the input recording data on the basis of the correction information, and determines whether the poor recording has occurred on the basis of a comparison result between the input recording image information obtained by the detecting by the camera unit and the corrected input recording data after recording the input recording data on the recording medium as an input recording image.
