A method of analyzing images is performed at a computer system that is in communication with an image acquisition device having an image sensor. The method includes receiving a reference template that includes a sync region and an inspection region that is located at an offset from the sync region. The method also includes acquiring a continuous sequence of image frames from the image sensor and storing each of the image frames in a buffer within the computer system's memory. The method further includes, for each image frame in the buffer, determining whether the image frame includes a sub-region matching the sync region. The method also includes, in accordance with a determination that the image frame includes a sub-region matching the sync region, capturing an inspection region within the image frame at the offset from the sub-region, and storing the captured inspection region to a non-volatile portion of the memory.

An image processing apparatus includes an acquisition unit configured to acquire a read image obtained by reading a printed document, and a determination unit configured to determine presence or absence of a streak included in the read image, by tracking a contour of the printed document from each of a plurality of points that are both end points of the read image in a direction orthogonal to a reading direction of the read image.

A 3D printer includes a nozzle configured to jet a drop of liquid metal therethrough. The 3D printer also includes a light source configured to illuminate the drop with a pulse of light. A duration of the pulse of light is from about 0.0001 seconds to about 0.1 seconds. The 3D printer also includes a camera configured to capture an image, video, or both of the drop. The 3D printer also includes a computing system configured to detect the drop in the image, the video, or both. The computing system is also configured to characterize the drop after the drop is detected. Characterizing the drop includes determining a size of the drop, a location of the drop, or both in the image, the video, or both.

To obtain a printing inspection device that an optimum binarization threshold value in the printing inspection device that captures an image including a two-dimensional code printed by a general-purpose printer such as an ink jet printer, as a multi-level image, creates a binary image from the multi-level image with a predetermined binarization threshold value, and then performs decoding. Before a practical printing inspection is performed, a read test is performed. The read test is performed on one or more inspection samples by binarizing a multi-level image with brightness values for all gradations as a threshold value. A range (maximum value and minimum value) of readable brightness values is obtained, and then a median value between the minimum value and the maximum value is used as a binarization threshold value for a two-dimensional code image in a practical printing inspection.

An information processing apparatus includes circuitry configured to display a display screen. The display screen includes a first display or a second display, and a third display. The first display displays, in units of a print job, checking result information obtained by comparing a read result with reference data on an image to be formed on the recording medium. The read result is obtained by reading a recording medium having an image formed. The second display displays, among print jobs, only a print job including a page having at least one abnormality in the image formed on the recording medium based on the checking result information. The third display displays information about the page in the print job including the page having the at least one abnormality and abnormality type information indicating a type of the at least one abnormality present in the page.

An apparatus includes a control system that defines a test part having multiple features of multiple feature types. The control system controls an additive manufacturing (AM) machine to print multiple copies of the test part, with each copy being printed according to a respective set of values used as printing parameters. A measurement system obtains a computed tomography (CT) image of each of the copies of the test part. An analysis system, for each of the plurality of feature types, analyzes the CT images to identify a selected set of values for the printing parameters. The analysis system identifies a portion of the CT image related to a first feature and assesses its density based on an average grayscale value. The AM machine is then controlled to print production parts according to, for each feature type of the production parts, the selected set of values for the printing parameters.

An image processing apparatus compares a target image and a reference image and thereby detects an anomaly in the target image, and includes an anomaly detecting unit. The anomaly detecting unit is configured to (a) generate a first characteristic map obtained by performing a filter process for the target image and a second characteristic map obtained by performing the filter process for the reference image, (b) derive a correction amount on the basis of a deviation between an object in the first characteristic map and an object in the second characteristic map, and (c) correct the target image and/or the reference image with the correction amount and thereafter compare the target image and the reference image and thereby detect an anomaly in the target image.

An object is to perform both quality maintenance of a printed material and suppression of a reduction in productivity of a printing apparatus by performing density correction processing at appropriate timing that takes into consideration the state of the printing apparatus. The above-described object is implemented by accumulating inspection results of printed sheets that are output from the printing apparatus and causing the printing apparatus to perform density correction processing in a case where a color defect in which a destination color is not reproduced occurs successively a predetermined number of times or more at positions at which the color defect does not overlap another defect.

An image processing apparatus includes an acquisition unit configured to acquire a plurality of image data read from a plurality of areas of a print product, and an evaluation unit configured to obtain degrees of streaks in the plurality of areas and tilts in the plurality of areas using the plurality of image data and evaluate image quality of the print product based on the degrees and the tilts.

A method for manufacturing a semiconductor device includes obtaining a first image of a fluid dispense nozzle using a first camera, the fluid dispense nozzle configured to dispense fluid on a semiconductor substrate, obtaining a second image of the fluid dispense nozzle using a second camera, the second image having a higher resolution than the first image, determining a width of the fluid dispense nozzle at multiple intervals along the fluid dispense nozzle and a width of a spray pattern of a fluid being dispensed from the fluid dispense nozzle at multiple intervals along the spray pattern, fitting a first straight line to a series of data points representing a plurality of widths of the intervals along the fluid dispense nozzle and a plurality of widths of the intervals along the spray pattern, determining a first slope of the first straight line, and determining a condition of the spray pattern and the fluid dispense nozzle based on the first slope.
