Title:
IMAGE READER
Document Type and Number:
Japanese Patent JPH11261779
Kind Code:
A
Abstract:

To provide the image reader that obtains an image with high resolution by making an image pickup element vibrate with an amplitude of N/M of a pixel width in a direction of pixel array.

An exciting means 12 makes an image pickup element 11 vibrate. In this case, a reference waveform generating means 14 generates a waveform to make the image pickup element vibrate with an amplitude of 1/M of a pixel width. Thus, an image is read with resolution in excess of twice in comparison with the case that the image pickup element is not made to vibrate in a direction of the pixel array. Moreover, acceleration required for the exciting means can be reduced, which results in the drive means configured at low cost.
