Disclosed is an imaging apparatus capable of, when a JPEG compression encoding is performed by dividing an image after an image processing into a plurality of blocks, simply performing the JPEG compression encoding and a combination of images after the encoding without encoding efficiency deterioration or a limitation in an image size of the block. The imaging apparatus includes an image processor for horizontally dividing image data into a plurality of blocks and supplying the blocks to an encoder without passing through a storage unit, the encoder for simultaneously storing an initiation address of a corresponding line to be encoded in a corresponding block and a data length after the corresponding line is encoded in the storage unit, and storing information used for a predictive encoding in the storage unit in every corresponding line to be encoded in the corresponding block.
