A method and system for rendering a correlation mark, can involve determining a combined path of a foreground comprising a first layer based on a first correlation pattern and a background comprising a second layer based on a second correlation pattern. The size of the second layer of the second layer can be calculated based on a trade off between how well the second layer hides a correlation effect and a readability of the second layer. The combined path can be filled with variable data at the size of the second layer at a selected color or a third correlation pattern to produce a two-layer correlation mark having a variable data hiding layer for rendering on or through a recording medium.

This application discloses an image generation method and apparatus, and an electronic device, and relates to the field of image processing. The method includes: acquiring a spectrum image of a first scene by using a first camera that supports more photosensitive bands than a second camera, and acquiring a color image of a second scene by using a second camera, where both the color image and the spectrum image include a same target object; then, correcting a color cast of a reconstructed spectrum image of the color image based on the spectrum image, to acquire a plurality of corrected reconstructed spectrum images; and fusing the plurality of corrected reconstructed spectrum images to generate a corrected color image whose color is closer to a color of the second scene than a color of the color image.

An image processing apparatus includes an extraction portion and a fusion portion. The extraction portion extracts a first object from each of a plurality of pieces of image data that include the first object and a second object, the first object including a handwritten object, the second object including a non-handwritten object. The fusion portion generates a fusion image by fusing a plurality of first objects extracted from the plurality of pieces of image data into the second object that is common to the plurality of pieces of image data.

An imaging apparatus includes an imager and an image converter. The imager captures an image of a subject to generate original image data representing the image captured with a predetermined resolution. The image converter performs a predetermined conversion process on the original image data. The image converter reduces a resolution of the original image data to generate first image data representing an entire image represented by the original image data with a resolution being lower than the resolution of the original image data. The image converter clips a part of the image represented by the original image data to generate second image data representing the part of the image clipped from the entire image represented by the original image data.

An image processing apparatus acquires a first image and a second image having a dynamic range wider than a dynamic range of the first image, generates a converted image by converting the dynamic range of the first image, and generates a composite image by compositing the second image and the converted image. The apparatus decides a composition range based on the second image, and converts the dynamic range of the first image into the composition range.

A system, method, and computer program product are provided for digital photography. In use, a digital package comprising two or more images, metadata, and a function or parameter is received. A first action is performed on the two or more images, wherein the first action includes at least one of: a recognition of at least one object within the two or more images; a determination of a location based on the recognition; or an identification of information associated with the at least one object. A second action is performed on the two or more images. A synthetic image is rendered based on the two or more images, the first action, and the second action.

Aspects of the subject disclosure may include, for example, performing, by a processing system, image fusion using two or more groups of images to generate predicted images, wherein each group of the two or more groups has one of a different resolution, a different frequency temporal pattern or a combination thereof than another of the two or more groups. Gap filling can be performed by the processing system to correct images of the two or more groups. Additional embodiments are disclosed.

An information processing apparatus sets a color mode in place of a monochrome mode on condition that the monochrome mode and multiplexing of additional information on a print target image are set as print settings based on an input image data; generates, based on the input image data, color image data corresponding to printing in a color mode which represents a color of the monochromated print target image by a value of a color signal; performs, for the color image data generated by the generation unit, processing for multiplexing the additional information on the print target image; and causes a printing apparatus to print, in the color mode, a multiplexed image on which the additional information is multiplexed.

Aspects of the subject disclosure may include, for example, performing, by a processing system, image fusion using two or more groups of images to generate predicted images, wherein each group of the two or more groups has one of a different resolution, a different frequency temporal pattern or a combination thereof than another of the two or more groups. Gap filling can be performed by the processing system to correct images of the two or more groups. Additional embodiments are disclosed.

A data structure defining a high dynamic range image comprises a tone map having a reduced dynamic range and HDR information. The high dynamic range image can be reconstructed from the tone map and the HDR information. The data structure can be backwards compatible with legacy hardware or software viewers. The data structure may comprise a JFIF file having the tone map encoded as a JPEG image with the HDR information in an application extension or comment field of the JFIF file, or a MPEG file having the tone map encoded as a MPEG image with the HDR information in a video or audio channel of the MPEG file. Apparatus and methods for encoding or decoding the data structure may apply pre- or post correction to compensate for lossy encoding of the high dynamic range information.
