In evaluation of the print quality of a symbol, the evaluation processing takes time. A symbol evaluation device () includes: a decoding unit () that decodes a symbol included in an image and thereby identifies reference position information of the symbol; a module position identification unit () that identifies a plurality of module positions included in the symbol on the basis of the reference position information of the symbol identified by the decoding unit; and a quality evaluation unit () that evaluates the quality of the symbol on the basis of the plurality of module positions identified by the module position identification unit.

Symbol evaluation device and evaluation method

An image processing device is connected to an imaging unit. The imaging unit has an overlapping region in an imaging range before and after continuous imaging. The image processing device includes: an interface that receives a plurality of captured images obtained by the imaging unit; a measurement unit configured to acquire a measurement result of a subject in the captured image by performing measurement processing to the captured image; a synthesis unit configured to generate a synthesized image by synthesizing the plurality of captured images such that the captured images overlap with one another within an overlapping range corresponding to the overlapping region in imaging order; and an output unit configured to output the synthesized image, information indicating the overlapping range correlated with the synthesized image, and information indicating the measurement result.

Image processing device and image processing program

An image processing method improves the extraction accuracy of objects other than symbols. The image processing method may include four processes. In the first process, an image is input. In the second process, a symbol in the image is read. In the third process, a mask area including the symbol is set. In the fourth process, an object located in an area other than the mark area in the image is recognized.

Method and apparatus for processing images, and storage medium storing the program

An image processing device includes: an image receiving part configured to receive an image of a target workpiece on a surface of a conveying path captured by means of the imaging unit; a position acquiring part configured to acquire a position of the target workpiece in the captured image; a tilt acquiring part configured to acquire, by using the position of the target workpiece in the captured image acquired by means of the position acquiring part, a tilt angle of an imaging plane of the imaging unit relative to the surface of conveying path; and an outputting part configured to output assistant information used for assisting in the adjustment of the posture of the imaging unit by using the acquired tilt angle.

This invention provides a parameter determination assisting device and a parameter determination assisting program enabling a more rapid and easy determination of a parameter to be set in a processing device, which obtains a processing result by performing a process using a set of parameters defined in advance on image data obtained by imaging a measuring target object. A user can easily select an optimum parameter set when a determination result and a statistical output are displayed in a list for each of a plurality of trial parameter candidates. For instance, while trial numbers '2', '4', and &#x201c;5&#x201d;, in which the number of false detections is zero, can perform a stable process, the parameter set of the trial number &#x201c;2&#x201d; is comprehensively assumed as optimum since the trial number &#x201c;2&#x201d; can perform the process in the shortest processing time length.
