Abstract
There is provided an image processing apparatus including a quantization unit that quantizes an image subjected to logarithmic conversion such that a quantization error is focused on a luminance region in which expansion of an error caused due to logarithmic inverse-conversion which is inverse conversion of the logarithmic conversion is relatively small or a luminance region in which no expansion of the error occurs; and an encoding unit that encodes an index image obtained through the quantization by the quantization unit.
