Abstract
Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.
Claims20
A computer-implemented method comprising:
- determining characteristic data of an image;
- determining, based on the characteristic data, a virtual aperture size of an optical system;
- causing the optical system to scan the image at a resolution based on a physical aperture size of the optical system;
- and
- modifying the resolution of the scanned image based on the virtual aperture size of the optical system.
An optical system comprising:
- one or more optical sensors to capture an image of a printed media;
- a processing circuitry in electronic communication with the one or more optical sensors, the processing circuitry being configured to:
- receive a print job defining specification of the image;
- determine characteristic data of the image from the print job;
- determine, based on the characteristic data, a virtual aperture size of the optical system;
- cause the optical system to scan the image at a resolution based on a physical aperture size of the optical system;
- and
- modify the resolution of the scanned image based on the virtual aperture size of the optical system.
A non-transitory computer-readable medium having computer-readable instructions stored therein, wherein the computer-readable instructions, when executed by a processor, cause the processor to:
- determine characteristic data of an image;
- determine, based on the characteristic data, a virtual aperture size of an optical system;
- cause the optical system to scan the image at a resolution based on a physical aperture size of the optical system;
- and
- modify the resolution of the scanned image based on the virtual aperture size of the optical system.
