IPC: H04N5/372
Filed: 1992-05-26
Abstract: PURPOSE:To provide the compact and inexpensive picture reader as a whole by obtaining a picture with an excellent MTF (modulation transfer function). CONSTITUTION:A light emitted from a light source 3 transmits through an original 2 and the image is formed on a CCD 15 via a mirror 5 and a lens 13 and photoelectric-converted into picture data. A control section 53 drives minutely the mirror 5 via piezo elements 55, 56 to move a read position of the original 2 by a half of the arrangement pitch of a light receiving element of the CCD 15. Similarly the CCD 15 is moved only by a half of the arrangement pitch of the light receiving element in an X direction and in X and Y directions. The picture at each read position is photoelectric-converted and the result is stored in a synthesis memory 8 for picture data. The picture data read in double fineness is obtained in both the X and Y directions by synthesizing the picture data read four times in total.
