  • System and method for analysis of test pattern image data in an inkjet printer using a template
    Patent number: 8651615
    Abstract: Test pattern template data are stored in a memory of a printer to identify locations spatially within image data of a test pattern printed by printheads in an inkjet printer. The test pattern template data identifies an origin of a test pattern in the image data and the distances between structures in the test pattern to enable test pattern structure in the image data to be detected and identified more easily.
    Type: Grant

  • Reflective sensor sampling for tone reproduction control regulation
    Patent number: 7643764
    Abstract: A method of monitoring one or more patches in an image-processing device comprised of photoreceptor, a controller, and a sensor, includes obtaining specular readings and diffuse readings from the one or more patches and computing values received from the readings. In addition, the one or more patches are from about 0.1 mm to equal or less than the field of view of the sensor where each patch size, location, and approximate value is known; and an analysis of variance (ANOVA) is automatically conducted from the known size, location, and approximate value of each patch.
