FIELD: processing of digital images, possible use in systems for capturing and compressing images, for example, photo-video-cameras. ^ SUBSTANCE: for known method of compression of digital images, including serial usage of operations for dividing unprocessed digital data, received from image capturing device, on a set of channels, with their following direct color transformation, wavelet transformation and quantization, suggested are changed rules of direct color transformation of channels, allowing more complete correlation between digital channels of image, resulting in possible compression of data to lesser size. Also, during processing of Byer's mosaic images suggested compression method allows transition to YCbCr color representation system, for which quantization coefficients are known. Usage of these coefficients results in production of compressed image of lesser size in comparison to quantization of original R, G, B channels. Suggested also is device for realization of method. ^ EFFECT: increased degree of compression of digital images. ^ 2 cl, 3 dwg |
