An image processing apparatus includes an image acquiring unit that acquires an original image data containing first data, and a data processing unit that edits the first data in the original image data thereby generating edited original image data, and outputs the edited original image data.

Digital watermark methods for encoding auxiliary data into a host signal are used to authenticate physical and electronic objects. One such method computes a content specific message dependent on the host signal, encodes the content specific message into a watermark signal, and embeds the watermark in the host signal such that the watermark signal is substantially imperceptible in the host signal. One specific implementation embeds data representing salient features of the host signal into the watermark. For example, for photo IDs, the method embeds the spatial location of salient features of the photo into the watermark. Another implementation computes a semi-sensitive hash of the host signal, such as a low pass filtering of the signal, and embeds the hash into the watermark. The watermark signal may be content dependent by making the watermark key dependent on some attribute of the signal in which the watermark is embedded. Another approach is to make the watermark key dependent on a user or an attribute of the user. Yet another approach is to use multiple watermark components and multiple watermark detection stages that help identify and screen out invalid watermark signals. Another digital watermarking method for authenticating a media object transforms a media signal to a frequency domain comprising an array of frequency coefficients. It selects a first set of frequency coefficients, and alters the selected first set of frequency coefficients so that values of the coefficients in the set correspond to a pattern. The pattern of the media signal is authenticated by comparing a pattern of the values of the frequency coefficients in the set with an expected pattern.

There is described a controlling program, a controlling apparatus, an image forming apparatus and a print controlling method, each to be employed in the variable-data printing. The controlling apparatus that controls a variable-data printing to create plural sets of print products based on print data provided with a variable field to which variable printing contents are to be applied for the plural sets of the print products, so as to convert the print data to raster image data, includes: a record acquiring section to acquire the plural records to be applied to the variable field; and a specifying section to specify, for each of the plural sets of print products, one kind of paper sheet out of plural kinds of paper sheets, based on correlation information in which the plural records and the plural kinds of paper sheets are correlated with each other.

A first image-data processing unit unifies characteristics of input image data so that the image data is usable in an image writing unit and an external device, stores characteristic-unified image data in a storing unit, and changes an attribute of supplemental information according to an image input condition. When converting target image data into image data with characteristics suitable for outputting to the image writing unit and an external interface unit, a second image-data processing unit makes the stored image data be reusable in the image writing unit and the external device by performing an image processing based on the supplemental information.

The present invention allows a specific image to be easily changed when using a counter in the case of adding a specific image. A specific image adding section 12 for adding the specific image to inputted image data includes a first counter 15 for deciding positions of a main scanning direction and a vertical scanning direction and a second counter 16 for specifying a form of the specific image. The second counter 16 counts up addresses of pixels counterclockwise with a starting point at one corner on a matrix made up of the main scanning direction and vertical scanning direction. If the first counter 15 counts a predetermined count value, the second counter 16 starts. When a maximum value of the count value of the second counter 16 is equal to or less than a count set value, an image is formed on each of the pixels. The pixel on which the image is formed is changed and the form of the specific image is also changed by changing the count set value.

An image processing apparatus includes: a storage unit that stores image information on which additional information is to be overlaid; a change unit that changes pixels, within a predetermined range of respective pixels constituting the image information, among pixels constituting the additional information, to pixels having a different density or color tint from a density or color tint of the image information and the additional information; and an overlay unit that overlays the additional information changed by the change unit on the image information held in the storage unit.

A camera includes a housing. An image sensor is fixed with respect to the housing and is configured to capture images. A print roll unit is releasably mounted within the housing. The print roll unit includes an elongate core, in turn, including a plurality of ink supply containers. Each container contains a respective type of ink. A roll of print media includes a tubular former in which the core can be received and a length of print media which is wound upon the former. A casing includes a pair of molded covers which can be releasably fastened together to encase the roll of print media, and defines a print media exit slot. A printer is housed in the housing, in fluid communication with the core, and is configured to print the captured images on the print media with ink stored in the core.

Steganographic signals or digital watermarks are detected from media signals. A media signal may represent audio, video or imagery. In one implementation, a method of detecting a digital watermark in a media signal is provided. The method includes receiving blocks of the media signal; buffering the blocks; screening the blocks for a presence of the digital watermark to identify a plurality of blocks likely to include the digital watermark based on a detection metric; combining the blocks that have been identified as being likely to include the digital watermark; and detecting the watermark from the combined blocks. Other implementations are provided as well.

A modified multi-page TIFF file. A Tagged Image Format File (TIFF) conforms to a published standard. The TIFF file contains an initial header, which contains a pointer to another header, which points both to (1) the first graphical image and (2) a second header. The second header points to both (1) the second image and (2) a third header, and so on. The headers allow a TIFF reader to locate any selected graphic image, and display it. The invention interleaves auxiliary information within the TIFF file, for example, between a header and a graphical image. The auxiliary information does not interfere with the TIFF reader, and the TIFF reader does not detect the auxiliary information.

A camera unit includes a chassis. An image sensor is mounted to the chassis and is configured to sense an image. A display is mounted to the chassis and is configured to display the sensed image. A printhead unit is mounted to the chassis and is configured to print the sensed image upon print media. The printhead unit includes an ink supply unit defining a plurality of ink channels for transporting respective types of ink. First and second recesses are located on opposite sides of the ink supply unit. An elongate printhead is received within the first recess to be in fluid communication with the ink channels. A lid is configured to be received within the second recess to seal the ink channels.
