  • Patent number: 10424066
    Abstract: Plural pieces of reference data are stored for plural pixel arrangement patterns. Each piece of reference data indicates which of first-type edge pixels needs to be subjected to determination to determine whether an outside neighboring first-type pixel adjacent to the first-type edge pixel exists. A piece of reference data corresponding to a target pixel block is specified as target reference data. A reference-data-based judgment is executed on the target pixel block to perform the determination onto those first-type edge pixels that are indicated by the target reference data as need to be subjected to the determination. A correction is executed on the target pixel block to correct the type of at least one first-type pixel contained in the target pixel block into the second type in a case where a result of the reference-data-based judgment indicates that no outside neighboring first-type pixel exists with respect to the target pixel block.

  • Patent number: 10270921
    Abstract: In an image analyzing apparatus, a controller acquires target image data representing a target image having a code image. The code image includes N number of code elements arranged in a first direction. N is an integer equal to or greater than 2. Each of the N number of code elements has two first sides parallel to a second direction orthogonal to the first direction. The controller specifies outline pixels configuring respective outlines of the respective N number of code elements from. The controller specifies a target inclination by analyzing the outline pixels. The target inclination indicates an inclination of the N number of code elements in the target image. The controller specifies a distance between two first sides of each of N number of code elements. The controller determines a representation form of the code image using the distances.
