FIELD: physics, computation hardware.SUBSTANCE: invention relates to computer engineering. Image coder comprises the components that follow. Colour space converter to convert hardware-dependent image data with floating point into hardware-independent image data with floating point. Determinant of limiting values to define maximum and minimum of image brightness index with floating point of every pixel of image portion, image or set of images. Converter floating point/integer to convert image brightness with floating point of every pixel to image brightness integer. Coder to encode image integer index of every pixel to obtain and to transmit encoded data of image portion, image of set of images.EFFECT: higher brightness resolution in hardware-independent colour space.13 cl, 9 dwg |
