Abstract: Various embodiments illustrated herein disclose a housing of an imaging unit. The housing comprising an outer surface and an inner surface, wherein the inner surface of the housing defines a lens channel, wherein the inner surface of the lens channel defines a contact point that protrudes outwardly from the inner surface into the lens channel. The inner surface of the lens channel further defines a through hole, in the lens channel, that extends from the inner surface of the lens channel to the outer surface of the housing. The lens channel is configured to receive a lens barrel comprising a groove, wherein the groove is exposed to the through hole when the lens barrel is received in the lens channel.

Abstract: Examples described herein relate to performing data compression by performing dictionary matching of data using hardware circuitry to generate dictionary matched results and post-processing of dictionary matched results using software executed by a processor. In some examples, dictionary matching includes LZ77 dictionary matching. In some examples, dictionary matching occurs on multiple segments of data in parallel.
