  • Patent number: 11140347
    Abstract: This disclosure relates to an imaging element, an imaging element control method, an imaging apparatus, and an electronic device adapted to suppress the drop in yield of the imaging element with an ever-higher density of circuitry. Multiple transfer paths are configured to transfer, bit by bit, a time code of a predetermined number of bits for use in converting into a digital signal a pixel signal reflecting the intensity of light received by a pixel. The transfer paths are provided with a relief transfer path that is switched for use in the case where an error has occurred on the multiple transfer paths. This disclosure may be applied to the imaging element.

  • Patent number: 5109437
    Abstract: A method for compressing digital data from an original bit stream into a coded bit stream useful for facsimile data transmission and digitized document image storage. The method comprises the steps of dividing the original bit stream into a plurality of data blocks and then comparing each of the data blocks with a reference block having a predetermined bit pattern. A coded bit stream is formed that comprises data blocks, compressed blocks and index blocks according to the following procedure. When a data block in the original bit stream is a mismatch with the reference block, the data block is included as is, without modification, in the coded bit stream along with an index bit indicating a mismatch in the index block. When a data block in the original bit stream is matched to the reference block, then compressed block is included in the coded bit stream along with an index bit in the index block indicating that the data block is matched.
