摘要： An error correction device error corrects without increasing in circuit scale. An encoder, includes: a first ECC encoder which interleaves a data string into n (n≧2) blocks of data strings at every m (m≧2) bits, and adds the error correction code parity; a parity encoder which creates a parity bit at every plurality of bits of the error correction code word, and adds the parity bit to said error correction code word; and a second ECC encoder, which generates a second error correction encoding, which is a linear encoding using iterative decoding. Concatenated type encoded data, where a parity bit is added to every plurality of bits, is created, so an increase of circuit scale can be prevented even if a data string is interleaved into a plurality of blocks and error correction code parity is generated.

摘要： One set of syndromes is calculated from a first data string from among a plurality thereof including at least 2t+1 pieces of symbols as a parity string, and coefficients of an error locator polynomial from the one set of the syndromes. Whether or not a correction is successful is judged by using the coefficients of the error locator polynomial and the same calculation is performed for a second data string if a correction failure is judged. Contrarily, if a correction success is judged, an error of the first data string is corrected by using the aforementioned set of the syndromes and the coefficients of the error locator polynomial.

摘要： When a zero run, which violating G constraint of a run-length-limited (RLL) code, is detected from the data stored in a first input register 1111 and a second input register 1112, bits before and after the zero run is transferred to a temporary register 1150 via a bus for zero run removal 1130 to be combined to each other. Thus, by effectively using the mechanism of bus transfer, a circuit can be simplified, thereby realizing a small circuit.

摘要： A dichroic mirror for reflecting red light for optical separating and a dichroic mirror for reflecting red light for optical synthesizing are installed on the same plane in an image generating apparatus of the present invention. In addition, a dichroic mirror for reflecting blue light for optical separating and a dichroic mirror for reflecting blue light for optical synthesizing are installed on the same plane. Accordingly, a compact configuration can be realized. Since a main reflecting mirror is a rotating elliptic mirror and a lamp is located on a focus or around the focus, a lighting equipment which irradiates conic luminous flux can be realized.
