According to intra-frame predictive coding and decoding methods based on template matching, an array scanning method and apparatus, and an apparatus are disclosed in embodiments of the present disclosure, where templates of at least two shapes are used to calculate predicted pixel values of a to-be-predicted unit. Templates of different shapes can represent different textures; when a correlation between a texture of a template of a shape and a texture of a to-be-predicted unit is low, a template of another shape may be selected and used, and a matching degree between a texture of a template and a texture of a to-be-predicted unit can be increased. In this way, an optimal predicted pixel value is determined from at least two predicted pixel values, and accuracy of the optimal predicted pixel value is higher than accuracy of a predicted pixel value determined by using a template of a single shape.
