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: 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: Disclosed is a method for re-sampling an input image comprising input samples to produce an output image comprising output samples. The method includes the following steps. A set of kernel values (130) is determined (110) based on a position (120) of an input sample (100), each kernel value in the set corresponding to a distinct output sample position. Each kernel value in the set is multiplied (105) by the value of the input sample to form a contribution. Each contribution corresponds to a distinct output sample and is first added (145) to a value in a corresponding storage location in an output accumulator (140), the result of the first addition replacing the contents of the storage location in the output accumulator. Each kernel value is also second added (135) to a storage location in a sliding kernel accumulator (150), the result of the second addition replacing the contents of the storage location in the sliding kernel accumulator. An accumulated output value, is read from the output accumulator (140), is divided (160) by a kernel weight read from the sliding kernel accumulator (150) to form an output sample at the output sample position. A position of the sliding kernel accumulator is advanced by one value.

Abstract: A method (500) of providing a picture composition guide on a display device (407) of a camera (450) is disclosed. The method (500) operates by firstly detecting (502) settings of the camera (450). Image analysis (503) is then performed on an image being displayed on the display device (407), the image representing a photographic scene. Next, the presence and location of strong features are determined based on the result of the image analysis (503). One or more markers are selected (505) dependent upon the camera settings and the strong features. The one or more markers are then superimposed over the image on the display device (407).

Abstract: A method (100) of marking an image comprising image data and associated metadata, for modification detection, is disclosed. The method (100) encodes the image data to produce encoded image data and hashes the encoded image data to provide a first hash. The first hash is added to the associated metadata to form augmented metadata the associated metadata is hashed to provide a second hash. The second hash is added to the augmented metadata. An association is created between the encoded image data, the first and second hash, and the augmented metadata, thereby marking the image.
