Additional image data of an additional image, which is based on first data and second data concerning security of obtained data, is added to image data that is based on the obtained data, and an image based on the image data to which the additional image data is added is outputted onto a recording medium, for example. Furthermore, when the additional image data is added to image data of the image obtained from the recording medium, the first data and second data are separated from the additional image data, and reference is made to these pieces of data to perform subsequent processing of the image data.

Image generating apparatus, image processing apparatus, image forming apparatus, and recording medium

In a digital multi-function peripheral, a QR code generation section generates image data of a QR code on the basis of first data for security of obtained image data. An encryption section encrypts second data for security of the image data. A micro gradation generation section generates a micro gradation (a gradation pattern) on the basis of the second data having been encrypted by the encryption section and history data, and adds the micro gradation to the image data of the QR code generated by the micro gradation QR code generation section.

Image processing apparatus for obtaining image data comprising a code generation section, an encryption section, a pattern generation section, and an addition section

A gradation pattern on the basis of the second data for the security of predetermined image data and the details data showing the detail information of a specific image of the image data is provided to a two-dimensional code on the basis of the first data for the security of the image data so that the data for the security of the image data is efficiently added to the image data in a limited space.

Image processing, reading or forming apparatus and method for adding specific image data to obtained image data while encrypting details data specifying specific data and adding encrypted details data to obtained image data, and non-transitory recording medium recording program for causing computer to function as the same

An image-processing apparatus, as well as an image-processing method, is provided with a first inspection circuit which, with respect to density values of pixels within a specific area consisting of a target pixel and pixels in a vicinity thereof in image data for each color component, calculates an average density value, the sum of density differences, that is, the sum of absolute values of differences between the target pixel and the peripheral pixels, and the number the peripheral pixels having the same density value as the target pixel, so that a judgement is made as to whether the target pixel is a maximum value or a minimum value, and also calculates a run-length and the degree of busy from the pixel forming the maximum value or the minimum value. Moreover, based on the run-length and the degree of busy, the second inspection circuit extracts a pixel weight switching signal for each of the color components, and detects the periodicity of meshes of image data by counting pixels not less than the standard value or not more than the standard value based on the pixel weight switching signal within a predetermined counting area. With this arrangement, it becomes possible to carry out the discrimination between character areas and mesh areas as well as the discrimination between black character areas and white character ares with high precision.

Image-processing apparatus and image-processing method

Function processor FP of a data driven type information processor includes mechanism A receiving plural field generation number GN (representing pixel coordinate information), instruction code OPC, and condition X determining a divisional configuration of the generation number. Mechanism A takes out a bit field designated by instruction code OPC and/or the condition from applied generation number GN. Data of the taken out bit field is sent to arithmetic and logic unit A. Arithmetic and logic unit A carries out operation between data of the bit field and right data R-DATA. The operation result is sent to mechanism B. Mechanism B receives instruction code OPC, generation number GN, and condition X determining a divisional configuration of the generation number. The above described operation result is stored in the bit field of generation number GN designated by instruction code OPC and/or condition X.
