A control apparatus for controlling a control target includes: an acquisition unit, a determination unit, and a delay time adding unit. The acquisition unit acquires at least first and second measurement values related to a control target, such as a machine. The determination unit determines whether the control target is in a predetermined state, such as a normal state or an abnormal state, based on the measurement values acquired by the acquisition unit. The delay time adding unit adds delay to at least one of the first and second measurement values.

Control apparatus, control program, control system, and control method

An image processing device includes a predicted position calculator configured to predict a current position of a target object, an obtained image analyzer configured to search for a position of the target object from a predetermined region that is a partial region of a captured image and that includes a position predicted by the predicted position calculator, and an analysis result outputting unit configured to output the position of the target object retrieved by the obtained image analyzer.

Image processing device, control system, control method of image processing device, control program, and recording medium

An image measurement system includes a controller, a projector for emitting illumination light in accordance with a radiation pattern, an imaging unit, and a display unit. The controller includes a display control module for displaying on a display unit an image of a field of view captured by the imaging unit in a state in which illumination light is emitted, a receiving module for receiving a setting of a mask area in association with the image displayed on the display unit, the mask area being an area in which the quantity of illumination light should be reduced compared with another area in the field of view, and an updating module for updating the radiation pattern in accordance with the set mask area, based on a correspondence in position between the radiation pattern of the projector and a projection pattern produced in the field of view by the radiation pattern.

Image measurement system and controller

The invention relates to a signal processing device, a control method thereof, a control procedure and a recording medium, which is unnecessary to increase a memory capacity for implementing sampling to determine a filter parameter. The signal processing device includes a data acquiring element (), acquiring signals of a time series, i.e. time series signals from a sensor; a filtering element (), performing a filtering operation according to frequencies; a transfer element (), transferring the time series signals; and a filter parameter determination element (), performing frequency analysis to the time series signals within a pre-specified interval, i.e. a specified interval to determine a filter parameter.

Signal processing device, control method thereof, control procedure and recording medium

An optical data code reader includes an illuminator device for illuminating an optical data code to be read out, an image-taking device for taking an image of this optical data code, a readout device for decoding the optical data code by processing image data generated by the image-taking device and an adjustment device for carrying out an adjustment process. The adjustment device adjusts an illumination condition of the illuminator device and/or an image-taking condition for the image-taking device such that the image data become suitable for being read out. The adjustment device serves to set areas on image data outputted by the image-taking device, to extract a variation amplitude of brightness in each of the areas and to carry out the adjustment process by using the image data of at least one of the areas in which the extracted variation amplitude is greater than a specified threshold value.

Device for reading optical data code

Image analyzer

A device for reading out an optical code includes a camera, an image memory for storing images taken by this camera, and an image processor for decoding an optical code contained in an image taken by the camera. A plurality of images are obtained continuously with the camera under specified image-taking conditions in response to a specified image-taking command, and the obtained images are stored on the image memory. The images stored in the image memory are sequentially selected one at a time in a specified order, and the image processor makes an attempt to decode an optical code contained in the selected image. Results of decoding are outputted if the attempt to decode any of the stored images is successful. The interval at which the images are taken is changed according to the number of images successfully decoded taken continuously in the past.
