Embodiment approach 1

[0021] Hereinafter, for one embodiment of the present invention, use Figure 1 to Figure 6 Describe in detail.

[0022] (Structure of Abnormality Judgment Device)

[0023] Regarding the configuration of the abnormality judging device 1 according to the present embodiment, using figure 1 Be explained. figure 1 It is a block diagram showing an example of the configuration of main parts of the abnormality determination device 1 .

[0024] The abnormality determination device 1 determines whether or not the imaging device 2 is abnormal based on imaging data obtained by imaging the light source 3 , which is an object with uniform brightness, by the imaging device 2 . According to the illustrated example, the abnormality determination device 1 includes a control unit 10 , a storage device 20 , a memory 30 , a display device 40 , and a data input unit 50 . The control unit 10 includes a smoothing processing unit 11 and an abnormality determination unit 12 .

Abstract

Provided is an abnormality determining device capable of appropriately detecting presence or absence of an abnormality in an image capturing device. An abnormality determining device (1) which determines, in accordance with imaging data on a subject (light source 3) having uniform brightness, whether or not an image capturing device (2) has an abnormality includes: a smoothing processing section (11) which generates smoothed image data by using a smoothing filter for each given range of divided data while moving a position of the smoothing filter by a range smaller than the each given range, the divided data being data obtained by dividing, into a plurality of regions, brightness data which is obtained by extracting brightness information from the imaging data; and an abnormality determining section (12) which compares the smoothed image data with the divided data and determines whether or not the image capturing device has an abnormality.

Description

technical field [0001] The present invention relates to an abnormality determination device and the like for detecting a defective product in an inspection of an imaging device. Background technique [0002] There is known a technique for inspecting whether or not the imaging device is a defective product by detecting foreign matter or the like mixed in at the manufacturing stage of the imaging device using an image captured by the imaging device. For example, Patent Document 1 discloses an inspection device that compares an n-order fitting curve generated by applying the least squares method to digital source image data with the digital source image data to determine whether there is a foreign object, and to check whether the imaging device is faulty or not. Good product, the digital source image data is obtained by photographing the reference plane of the inspected object.
