An apparatus for concealing error data of pixel data in a digital image signal. The apparatus includes a deframing circuit for detecting errors every predetermined unit to generate a first error flag in high order bit planes including at least the most significant bit plane of bit planes of pixel data in a received digital image signal and for forming a second error flag representing the presence or absence of an error in each of the bits forming the pixel data every pixel data in the high order bit planes on the basis of the first error flag. The apparatus further includes an error correcting device for calculating a plurality of possible data values of the pixel data and for selecting one data value from among the plurality of possible data values, taking the correlation between the pixel data and surrounding pixel data into consideration, on the basis of the second error flag representing the presence or absence of an error in each of the bits forming the pixel data when the pixel data has an error.
