Abstract

An image recording and color measuring device for recording image data and color data of a surface of an object. The image recording and color measuring device including: at least one camera module with a line sensor; a first lens system associated with the line sensor to focus light rays; at least one color sensor; and a second lens system associated with the color sensor. The image recording and color measuring device recording image data of one point on the surface of the object with the camera module at the same time as color measuring data is recordable for the one point with the aid of the at least one color sensor. A plurality of image data and color data from individual points provide a total volume of image and color data of the object.

Claims

1. An image recording and color measuring device for recording image data and color data of a surface of an object comprising:

at least one camera module with a line sensor;

a first lens system associated with the line sensor to focus light rays;

at least one color sensor; and

a second lens system associated with the color sensor,

wherein image data of respectively one point on the surface of the object is recordable with the camera module at the same time as color measuring data is recordable with the aid of the at least one color sensor, and wherein a plurality of image data and color data from individual points provide a total volume of image and color data of the object.

2. The image recording and color measuring device according to claim 1,

further including a housing inside of which the image recording and color measuring device is arranged.

3. The image recording and color measuring device according to claim 2, wherein the image recording and color measuring device functions as a print inspection device for the inline inspection of an image printed onto an object.

4. The image recording and color measuring device according to claim 1, wherein the image recording and color measuring device includes at least one light source, arranged in and on the housing and a third lens system to focus the light rays to at least partially illuminate the object.

5. The image recording and color measuring device according to claim 4, wherein the first, the second and the third lens systems are arranged so that light rays which pass through the lenses of the systems converge in a point or on a line.

6. The image recording and color measuring device according to claim 1, wherein the line sensor comprises a monochrome line sensor.

7. The image recording and color measuring device according to claim 1, wherein the at least one color sensor comprises one of:

RGB color sensors,

spectral sensors, or

color sensors having a YXZ tri-stimulus output.

8. The image recording and color measuring device according to claim 1, wherein the second lens system comprises at least one of:

an elongated lens

at least one glass fiber for transmitting electromagnetic waves between the point on the object and the at least one color sensor; and

a cross section converter.

9. The image recording and color measuring device according to claim 1, further comprising an electronic component including a data storage and data processing device, wherein the at least one color sensor and the camera module are electronically coupled to communicate with the data storage and data processing device of the electronic component.

10. The image recording and color measuring device according to claim 1, further comprising at least one printed circuit board, wherein the at least one color sensor and the camera module are arranged on the at least one printed circuit board.

11. The image recording and color measuring device according to claim 1, further comprising:

at least one device for synchronizing the simultaneously recorded image data and color measuring data.

12. The image recording and color measuring device according to claim 2, wherein the housing includes at least one opening for heat dissipation.

13. An image recording and color measuring system, comprising:

a housing; and

a plurality of individual image recording and color measuring devices according to claim 1 arranged adjacent to each other or opposite each other inside the housing.

14. The image recording and color measuring system of claim 13, wherein each of the plurality of individual image recording and color measuring devices simultaneously record an image data and color measuring data pair for a plurality of points on the surface of the object, and wherein simultaneously recorded image and color data pairs obtained from the plurality of points provide a total volume of image data and color data of the object.

21. A method of inline inspection of an image printed on an object, comprising utilizing the image recording and color measuring device according to claim 1.

15. A method for image recording and color measuring of image data and color data of a surface of an object with an image recording and color measuring device that includes at least one camera module with a line sensor, a first lens system associated with the line sensor to focus light rays, at least one color sensor, and a second lens system associated with the color sensor, the method comprising the steps of:

(1) recording image data of a point on the surface of the object with the camera module and the first lens system; and

(2) simultaneously with step (1) recording color measuring data of said point with the at least one color sensors and the associated second lens system; and

(3) repeating the steps (1) and (2) for other individual points on the surface of the object to obtain a total volume of image data and color data from a plurality of individual points of the object.

17. The method according to claim 15 including implementing the steps in a printing press for inline inspection of an image that is printed onto an object.

18. The method according to 17, further comprising the step of:

illuminating the image printed onto the object with the aid of a light source that is arranged on or in the housing.

16. A method for image recording and color measuring of image data and color data of a surface of an object with an image recording and color measuring system comprising a housing and a plurality of image recording and color measuring devices arranged adjacent to each other or opposite each other inside the housing, each image recording and color measuring device including at least one camera module with a line sensor, a first lens system associated with the line sensor to focus light rays, at least one color sensor, and a second lens system associated with the color sensor, the method comprising the steps of:

(1) recording image data of a first point on the surface of an object with the camera module and first lens system of a first image recording and color measuring device;

(2) simultaneously with step (1) recording color measuring data of said first point on the surface of the object with the at least one color sensor and said second lens system of said first image recording and color measuring device to produce a first image and color measuring data pair for said first point;

(3) simultaneously performing steps (1) and (2) with at least another image recording and color measuring device to produce at least another image and color measuring data pair for said first point; and

(4) repeating the steps (1), (2), and (3) for at least a second point on the surface of the object to produce image and color measuring data pairs for the at least second point, wherein steps (1) through (4) produce a total volume of image and color data from a plurality of individual points on the object.
