A method and an apparatus arranged to obtain raw image data acquired by an image sensor to be applied in an image processing algorithm; adjust, in the processor miming the image processing algorithm, logical dimensions of the image such that logical width of the image is doubled and logical height of the image is halved; adjust the image processing algorithm to take into account the adjusted logical dimensions of the image; and apply the image processing algorithm with the adjusted logical dimensions of the image.

Arrangement for image processing

A method, apparatus and computer program product are provided herein to enable buffer initialization and/or clearance to occur on, for example, a mobile terminal. In some example embodiments, a method is provided that comprises receiving an indication that a buffer has been initialized by a host. The method of this embodiment may also include receiving source code from the host. In some example embodiments, the source code is received from a program running on the host and is configured to cause the buffer that has been initialized by the host to be cleared. The method of this embodiment may also include executing the source code such that the buffer that has been initialized by the host is cleared.

Method and apparatus for buffer initialization

A method for encoding an image having color components of each image pixel represented by a value of a high dynamic range, the method comprising: decomposing the image into a plurality of image blocks; separating, from the high dynamic range value of each pixel, color information and intensity information of the pixels in said image blocks; and compressing the color information of the pixels in said image blocks and the intensity information of the pixels in said image blocks independently of each other to provide compressed image data.
