Scanning non-flat objects with a 2-D CMOS/CCD sensor
An apparatus for scanning non-flat objects. The apparatus includes a sensor scanning a non-flat object to thereby produce a real-time preview of an image of the object, the sensor being a 2-D CMOS sensor or a 2-D CCD sensor, followed by a final scan of the non-flat object. The apparatus further includes a controller controlling a tilting angle and a height of the sensor with respect to the object in accordance with adjustments by a user viewing the preview of the image. The apparatus captures the image with the tilting angle and height controlled sensor.
1 . An apparatus comprising:
a sensor scanning a non-flat object to thereby produce a real-time preview of an image of the object, the sensor being a 2-D CMOS sensor or a 2-D CCD sensor; and
a controller controlling a tilting angle and a height of the sensor with respect to the object in accordance with adjustments by a user viewing the preview of the image, wherein the apparatus captures the image with the tilting angle and height controlled sensor.
2 . The apparatus of claim 1 , further comprising:
a tilting device to house the sensor, wherein the controller controls tilting and height adjustments of the sensor in the tilting device.
3 . The apparatus of claim 2 , further comprising a display unit to allow a user to view the preview of the image in real-time while the user adjusts a position of the non-flat object and zoom characteristics of the image via the display unit.
4 . The apparatus of claim 1 , further comprising data buffers to temporarily store image data corresponding to the captured image, thereby enabling the sensor to scan another non-flat object.
5 . The apparatus of claim 4 , further comprising a built-in printer to print the captured image, wherein the stored image data is transferred to the built-in printer to print the captured image.
6 . The apparatus of claim 4 , wherein the apparatus is connected to a computer system and the stored image data corresponding to the captured image is transferred to the computer system.
7 . The apparatus of claim 1 , further comprising a character recognition program to enable the apparatus to scan full-page text documents.
8 . An apparatus comprising:
a first sensor scanning a first portion of a non-flat object to thereby produce a real-time preview of an image of the first portion of the non-flat object;
a second sensor positioned relative to the first sensor scanning a remaining portion of the non-flat object to thereby produce a real-time preview of an image of the remaining portion of the non-flat object, the first and second sensors being 2-D CMOS sensors or 2-D CCD sensors; and
a controller controlling a tilting angle and a height of the first and second sensors with respect to the first and the remaining portions of the non-flat object respectively, in accordance with adjustments made by a user while viewing the previews of the images of the first and remaining portions of the non-flat object, wherein the apparatus captures the images of the first and remaining portions of the non-flat object with the adjustments.
9 . The apparatus of claim 8 , further comprising an image processor, wherein the images captured by the first and second sensors are combined into one image by the image processor.
10 . A method comprising:
positioning a non-flat object, while viewing a real-time preview of an image of the non-flat object via a display;
adjusting zoom characteristics of the image via the display; and
capturing the image with the adjusted zoom characteristics via a sensor, the sensor being a 2-D CMOS sensor or a 2-D CCD sensor.
11 . The method of claim 10 , wherein the capturing the image of the non-flat object via the sensor comprises adjusting a tilting angle and height of the sensor prior to capturing the image.
12 . The method of claim 10 , further comprises:
storing image data corresponding to the captured image in data buffers;
processing the stored image data; and
printing the captured image of the non-flat object.
13 . An apparatus comprising:
a sensor scanning a non-flat object to thereby produce a real-time preview of an image of the object, the sensor being a 2-D CMOS sensor or a 2-D CCD sensor; and
means for controlling a tilting angle and a height of the sensor with respect to the object in accordance with adjustments by a user viewing the preview of the image, wherein the apparatus captures the image with the tilting angle and height controlled sensor.
14 . An apparatus comprising:
a first sensor scanning a first portion of a non-flat object to thereby produce a real-time preview of an image of the first portion of the non-flat object;
a second sensor positioned relative to the first sensor scanning a second portion of the non-flat object to thereby produce a real-time preview of an image of the second portion of the non-flat object, the first and second sensors being 2-D CMOS sensors and 2-D CCD sensors, wherein a scanning process of the first and second sensors are completed consecutively or simultaneously; and
means for controlling a tilting angle and a height of the first and second sensors with respect to the first and second portions of the non-flat object respectively, in accordance with adjustments made by a user while viewing the real-time previews of the images of the first and second portions of the non-flat object, wherein the apparatus captures the images of the first and second non-flat objects with adjustments, consecutively or simultaneously.
