  The image target separation unit 210 separates the document input to the image forming unit 202 for each image target (object) constituting the document (object separation).

FIG. 5 illustrates an outline of object separation by the image target separation unit 80.
The image target separation unit 210 is arranged for each object included in the input image information (for example, a position in the X direction, a position in the Y direction, a width, a height), and a type (for example, a character (text), a figure, an illustration ( (CG), photo, etc.), color, etc. are extracted, and an object list in which these are associated with identification numbers (ID) is created. The part where the object is not arranged is recognized as a background. The contents of the object list are schematically represented as a tag image and an object image.
It should be noted that the object may be detected in the upright direction by using OCR (Optical Character Reader) or the like for an object whose type is character. Thereby, the erecting direction of the printed matter including the object is determined.

In the example shown in FIG. 5, the input image information includes four objects by object separation by the image target separation unit 210, and each type is “illustration”, “photograph”, “figure”, “character”. It is grasped together with the arrangement of these four objects on the recording medium.
The image target separation unit 210 grasps the type of each document even for a document (for example, bitmap format) to which the type is not added.

The quality information detection unit 212 detects information related to the image quality of the printed matter (hereinafter sometimes referred to as “quality information”). Specifically, the quality information detection unit 212 compares the input image information and the image of the printed matter read by the image reading unit 204 for each object, and detects the quality information based on the difference. The quality information detection unit 212 detects quality information by pattern matching, for example.
“Quality information” includes, for example, defects in printed images (dot noise, streaks, color shifts, missing characters, weak edges, etc.).

FIG. 6 exemplifies the outline of the defect of the image. In this example, dot noise and streaks are generated in the case where the object type is “photograph”. The quality information detection unit 212 detects, for example, the number / location of dot noise per unit area, the density of streaks, and the like as the degree of image defects.
The degree of image defects is appropriately determined in consideration of dot noise, color misregistration, character missing, the number per unit area, the density of spots and stripes, or combinations of various image defects. Hereinafter, the degree of image defects may be simply expressed as “the number of noises” for convenience.

The quality standard setting unit 214 sets a quality standard for each object type. In the present embodiment, the quality standard is divided into a plurality of stages (levels) for each type, and a threshold is provided for each stage. The threshold value is determined corresponding to the degree of defect of various images.
The threshold value may be determined in advance or may be set as appropriate. The threshold value may be determined individually for each type according to the type, or may be set uniformly. For example, the threshold value is set to be finer and stricter for a type that requires relatively high image quality.

FIG. 7 illustrates quality standards set for each object. In the example shown in FIG. 7, quality standards are set in five stages for each of the object types “character”, “photo”, “illustration”, “figure”, and “background”.
For the type “character”, threshold values “A-Th05” to “A-Th01” are provided for each quality standard. For example, each threshold is the number of noises, the threshold “A-Th05” is “0”, the threshold “A-Th04” is “5”, the threshold “A-Th03” is “10”, and the threshold “A-Th02” Is defined as “15”, and the threshold “A-Th01” is defined as “20”.
For the type “Photo”, threshold values “B-Th05” to “B-Th01” are provided for each quality standard. For example, each threshold value is the number of noises, the threshold value “B-Th05” is “0”, the threshold value “B-Th04” is “2”, the threshold value “B-Th03” is “4”, and the threshold value “B-Th02” Is defined as “6” and the threshold “B-Th01” is defined as “8”.
Similarly, thresholds are determined for types of “illustration”, “figure”, and “background”.

  The quality standard setting by the quality standard setting unit 214 is performed based on an operator instruction received by the UI device 130, the terminal device 2, or the like, for example.

  FIG. 8 illustrates an operation screen operated by the operator. In the example shown in FIG. 8, the quality standards are selected in five stages for each of the object types “character”, “photo”, “illustration”, “graphic”, and “background”. Depending on the characteristics of the printed material and the purpose of use (for example, whether the printed material is external or internal, or whether the printed material is a brochure, flyer, form, etc.) A quality standard is appropriately selected for each type.

Based on the object list created by the image object separation unit 210, the quality information detected by the quality information detection unit 212, and the quality standard set by the quality standard setting unit 214, the quality determination unit 216 Determine the quality. Specifically, the quality determination unit 216 grasps the degree of defect for each object based on the object list and the quality information, and the degree of defect is set for each object (type of each object). Determine whether quality standards are met.
In the present embodiment, when there is one or more objects that do not satisfy the quality standard in the printed material, the quality determining unit 216 determines that the quality of the printed material is unacceptable. Depending on the number of objects that do not satisfy the quality standard, the quality of the printed matter may be more finely discriminated, for example, by dividing it into three or more stages without being limited to two stages of pass / fail.

  For example, it is assumed that the quality standard “level 3” is selected for the object type “character” and the threshold value “A-Th03” is set to “number of noises 10” (see FIGS. 7 and 8). In this case, for an object of type “character” (in the example shown in FIG. 5, an object with ID “04”), if the number of noises is 10 or more, the quality of the printed matter including this object is “failed”. It is determined that On the other hand, if the number of noises for this object is less than 10 and it is determined that the quality standards of other objects are also satisfied, the quality of this printed matter is determined to be “pass”.

  Further, for example, it is assumed that the quality standard “level 5” is selected for the object type “photo”, and the threshold value “B-Th03” is defined as “the number of noises is 0” (see FIGS. 7 and 8). . In this case, for an object of type “photo” (in the example shown in FIG. 5, an object of ID “02”), if the number of noises is 1 or more (if noise exists), a printed matter including this object Is determined to be “failed”. On the other hand, if the number of noises for this object is 0 (no noise is present) and it is determined that the quality standards of other objects are also satisfied, the quality of this printed matter is determined to be “pass”.

The discrimination result output unit 218 outputs the discrimination result of the quality discrimination unit 216. In the present embodiment, the printed matter whose quality is determined to be “pass” is discharged to the discharge tray 112a, and the printed matter whose quality is determined to be “fail” is discharged to the discharge tray 112b. The switching unit 114 is operated.
Note that the determination result of the quality determination unit 216 may be displayed on the UI device 130, the terminal device 2, or the like together with the change of the discharge destination or alone.

As described above, the image inspection unit 206 determines the image quality of the printed material based on the quality standard set for each type of object.
For example, there is a case where higher image quality is required for the photographic portion than for the character portion due to the characteristics of the printed matter and the purpose of use. At this time, when setting a uniform quality standard for the entire printed material, if a quality standard that matches the “photo” part is set, this quality standard is also applied to the “character” part. Excessive discrimination may be made. On the other hand, when setting quality standards for each type, setting a high quality standard only for the photo part suppresses the gap between the quality actually requested for the printed matter and the quality standard for judging the quality. The Rukoto.

Based on the above, the quality of the printed matter is determined.

  In step 114 (S114), the discrimination result output unit 218 outputs the discrimination result by the quality discrimination unit 216.

The setting of the quality standard by the quality standard setting unit 214 is not limited to the configuration performed by the operator via the UI device 130 or the like, but may be stored in the storage device 144 in advance.
The quality standard setting unit 214 sets the quality standard for each type of object, and in addition to the type and material of the recording medium (for example, which is plain paper, recycled paper, glossy paper, label paper, etc.) A quality standard may be set for each characteristic / use of the printed matter (for example, external or internal, or a pamphlet, a flyer, a form, or the like).
