ABSTRACT:
In a coding apparatus, a first detecting device serves to detect a variation between conditions of pixels in a currently-coded line. A second detecting device serves to detect a variation between conditions of pixels in a reference line which immediately precedes the currently-coded line. A deciding device serves to decide a mode of MR coding in accordance with the variations detected by the first and second detecting devices. The first and second detecting devices and the deciding device are enabled to execute functions thereof in temporally parallel with each other.
