Abstract: A method (700) of determining an image value at a sample position of an output image, is disclosed. The method (700) comprises the steps of determining orientation of an isophote (e.g., 1010) passing through the output sample position and determining a period of intensity variation along the isophote (1010). The method (700) determines the image value at the sample position of the output image based on the period of intensity variation and outputs the determined image value at the sample position of the output image.

Abstract: A method of removing an artefact from an image captured with a motion invariant camera is disclosed. The captured image is de-blurred using a spatially invariant blur kernel. An edge filter with a fixed offset is applied to the de-blurred image to identify the location of at least one artefact. A parameter is estimated based on a region either side of the identified location. The at least one artefact is removed from the de-blurred image using the parameter.

Abstract: Methods of capturing image pixel data representing a scene may be practiced using a camera and may be implemented as software, such as an application program executing within the camera. The methods are particularly advantageous where user modification to the camera control parameters leads to a difference between the values of the pre-capture control parameters for the camera when compared to the pre-capture control parameters that the camera would determine in fully automatic mode. The measured difference may be compared to one or more predetermined threshold values.
Abstract translation: 可以使用相机来实现捕获表示场景的图像像素数据的方法,并且可以被实现为诸如在相机内执行的应用程序的软件。 这些方法特别有利的是,当相机控制参数的用户修改导致相机预拍摄控制参数的值与相机将在全自动模式下确定的预拍摄控制参数相比时,这些方法之间的差异导致相机的预拍摄控制参数的值之间的差异。 可以将测量的差异与一个或多个预定阈值进行比较。

Abstract: A method of reconstructing an image, where the input image data is preferably part I or part II compliant JPEG2000 coded data, or pixel data of the original image. The method selects (810) an output resolution R, and then determines a number of sub-passes to extract from each block code based on the selected resolution. The method then extracts (830) the determined sub-passes and the remaining sub-passes are discarded. The method then reconstructs 840 the image from the extracted sub-passes. The reconstructed image can be in the form of the selected resolution of the original image, or it can be in the form of compressed image data of the selected resolution of the original image.

Abstract: A method (100) of generating a digital image of a scene is disclosed. The method (100) is particularly advantageous in situations where a light source illuminating the scene is unknown. The method (100) allows post-capture control over flash illuminant and ambient illuminant used in generating the image. The method (100) may also be used to provide a synthetic fill flash effect. The method (100) is particularly advantageous in situations where an ambient light source illuminating the scene differs in spectral character from that of a flash illuminant used to capture an image of the scene.

Abstract: A method of processing a multi-layer image file (100) comprising a first plurality of image layers (106-108), and a second plurality of control blocks (120-122) is disclosed. The processing produces an animation sequence. The method comprises processing an image layer (eg 106) in accordance with a corresponding control block (eg 120), thereby providing an image for said animation sequence. The method further comprises tagging the image layer (106) for reprocessing, if the image layer (106) is to be used again in the image sequence, said tagging using a relative address referred to one of (i) an address of said corresponding control block (120) and (ii) an address of a control block corresponding to another image layer.

Abstract: A method, an apparatus, and a computer program product for signalling a structure of a code stream comprising a plurality of code segments are disclosed. In the method, a code segment indexing order is determined based on a reference order for the code segments and a set of permutation values for modifying ordering of indices of the reference order. The code segment indexing order is used for signalling the structure of the code stream. The reference order is preferably dependent upon a predetermined coding process for producing the code stream. The code stream may relate to a decomposed, digital image, but may alternatively relate to audio and/or video data.
