Abstract:
A display unit color-correction method includes: a first step of displaying a prescribed image on a display unit of a portable communication terminal that includes an imaging unit and the display unit; a second step of acquiring imaging data by imaging a color chart, which is a printed matter, and the display unit with the prescribed image displayed thereon together or individually by the imaging unit; and a third step of correcting a color of the display unit by using color information on the prescribed image in the imaging data and color information on a color in the color chart in the imaging data.
Abstract:
An image forensics system estimates a camera response function (CRF) associated with a digital image, and compares the estimated CRF to a set of rules and compares the estimated CRF to a known CRF. The known CRF is associated with a make and a model of an image sensing device. The system applies a fusion analysis to results obtained from comparing the estimated CRF to a set of rules and from comparing the estimated CRF to the known CRF, and assesses the integrity of the digital image as a function of the fusion analysis.
Abstract:
The image processing apparatus of the present invention is characterized by including an obtaining unit configured to obtain image data and a detection result of a main subject in the image data; a detecting unit configured to apply main subject detecting processing to the image data obtained by the obtaining unit; a coincidence determining unit configured to determine whether a detection result of the main subject obtained by the obtaining unit and a detection result of the main subject detected by the detecting unit coincide with each other; and a correction amount determining unit configured to determine an amount of correction to be applied to the image data in accordance with a determination result obtained by the coincidence determining unit. Image correction processing is performed in a determined correction processing manner.
Abstract:
Methods, systems, and articles of manufacture to enhance automation of conversion and/or persistent storage of color management information embedded within an associated, received data object. Features and aspects hereof provide that color management information embedded within an identified data object (e.g., an image data object) is converted to an appropriate form useful within the printing environment and persistently stored for re-use in conjunction with presentation of received data objects in a print job. For example, an ICC profile embedded within a received image data object may be converted to an AFP color management resource (a color conversion CMR and/or zero or more link CMRs) and persistently stored in an object library for re-use in presentation of print jobs. The conversion and persistent storage of such color management information may be substantially automated as a step in the installation of the underlying data object.
Abstract:
An image processing apparatus includes a storage unit, a judgment unit and a conversion unit. The storage unit stores a reference color characteristic. The judgment unit judges as to whether or not a difference between an input color characteristic that is a color characteristic of input image data and the reference color characteristic is equal to or less than a predetermined threshold value. The conversion unit converts the input image data into a color characteristic that can be reproduced by an image reproducing apparatus, based on the reference color characteristic if the difference is equal to or less than the predetermined threshold value.
Abstract:
The electronic camera has an imaging device that images a subject with subject reflectance R (%) with a dynamic range wider than that at displaying or printing to acquire image data and a recording device that converts the image data acquired by the imaging device with a predetermined function and records the converted image data and the information on the function as digital values (digit). Therefore, a printed image with an automatically or manually corrected density can be obtained at the displaying or the printing.
Abstract:
An information processing apparatus inputs image data including a first pixel group, a second pixel group generated by interpolating the first pixel group and verification data of the first pixel group, verifies whether the first pixel group has been altered using the first pixel group and the verification data, verifies whether the second pixel group has been altered by determining whether the second pixel group and the first pixel group are in a predetermined relationship, and determines whether the image data has been altered based on results of the verification as to whether the first pixel group has been altered and the verification as to whether the second pixel group has been altered.
Abstract:
An updating unit updates a color-conversion table stored in a storing unit. An image processing unit processes an input image data based on updated color-conversion table. A tamper-resistant chip that includes a first collecting unit that collects log information related to a usage of the image processing apparatus, a generating unit that generates a hash value corresponding to collected log information, and a recording unit that records generated hash value. An acquiring unit acquires the log information corresponding to the hash value by referring to recorded hash value. The updating unit updates the color-conversion table based on acquired log information.
Abstract:
A system and method for image acquisition enables selective automated application of color management to color image data generated by an image-capturing device by the device driver for the device. In the image acquisition system, each image-capturing device has properties or operation parameters that can be set to control the operation of the device. During an image acquisition operation, color image data generated by the image-capturing device are transmitted to the device driver. If the operation parameters of the device are set to indicate that color management is to be performed, the device driver calls color management functions provided by the operating system to perform the desired color operation, such as a color space conversion, on the received color image data. The processed color image data are then sent to the image-processing application for further processing or editing.
Abstract:
When an acquired image file GF includes image processing control information GI, a CPU executes image quality adjustment of image data GD in an image processing mode GM specified by the image processing control information GI. When the acquired image file GF does not include the image processing control information GI, on the other hand, the CPU retrieves Exif information and in the case of successful retrieval of the Exif information, selects the image processing mode GM based on the Exif information and executes image quality adjustment of the image data GD in the selected image processing mode GM. In the case where a selected shooting mode is described in the Exif information, the selected shooting mode is used for the selection of the image processing mode GM. In the case where no selected shooting mode is described in the Exif information, on the other hand, another shooting condition is used for the selection of the image processing mode GM.
