Abstract
An image identification apparatus for identifying an image from a hand drawn representation of at least part of the image, the image identification apparatus comprising an image processor arranged in operation to generate a reference identification in response to spatial samples produced from at least part of the hand drawn representation, the reference identification being indicative of a first estimate of which of a plurality of pre-stored images corresponds to the hand drawn representation. and a controller which is arranged in operation to cause the image processor to produce a refined reference identification from the spatial samples and further spatial samples produced from a further part of the hand drawn representation, the refined reference identification being indicative of a refined estimate of which of the plurality of the prestored images corresponds to the hand drawn representation. The controller is arranged to operate with the image processor to generate further refined estimates of the identification of the image from subsequent hand drawn parts of the image.
