Methods and apparatuses for coding and decoding mode information and electronic device. The method for coding includes determining a uniform transform block mode adopted by a coding block of an image; determining a binary bit to which the uniform transform block mode corresponds according to a size of the coding block and/or a determined number of uniform transform block modes; and coding the binary bit to which the uniform transform block mode corresponds into a bit stream of the image. Hence, for example, not only uniform transform block mode information may be coded and decoded, but also bit costs of coding may be lowered.
