Olympus Corporation is a Japan-based manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscope and thermometer businesses. Olympus enjoys a majority share of the world market in gastro-intestinal endoscopes. It has a roughly 70% share of the global market whose estimated value is US$2.5 billion. Its global headquarters are in Shinjuku, Tokyo, Japan.In 2011, the company gained coverage in global media when it fired after two weeks its newly appointed British chief executive Michael Woodford, a 30 year Olympus veteran, and Olympus' president and chief operating officer since April that year, who had sought to probe financial irregularities and unexplained payments of hundreds of millions of dollars following his appointment as CEO. Although the board initially dismissed Woodford's concerns via mass media as being "disruptive" actions and Woodford as failing to grasp local culture, the matter quickly snowballed into a corporate corruption scandal over concealment of more than 117.7 billion Yen of investment losses and other dubious fees and other payments dating back to the late 1980s and suspicion of covert payments to criminal organizations. By 2012 the scandal had developed into one of the biggest and longest-lived loss-concealing financial scandals in the history of corporate Japan; it had wiped 75 - 80% off the company's stock market valuation, led to the resignation of much of the board, investigations across Japan, the UK and US, the arrest of 11 past or present Japanese directors, senior managers, auditors and bankers of Olympus for alleged criminal activities or cover-up, and raised considerable turmoil and concern over Japan's prevailing corporate governance and transparency and the Japanese financial markets. Woodford himself, who stated he had received death threats over his exposing of the cover-up, received a reported £10 million in damages from Olympus for defamation and wrongful dismissal in 2012; around the same time, Olympus also announced it would shed 2,700 jobs and around 40 percent of its 30 manufacturing plants by 2015 to reduce its cost base. The company is owned 17% by two large camera makers, Sony and Mitsubishi . Wikipedia.


A decoding device includes: a data obtaining unit configured to obtain a key block and a non-key brock, the key block forming a part of image data of one frame, and the non-key block forming a part of the image data of one frame on at least a part of which a coding process is performed; a characteristic information storage unit configured to store characteristic information regarding a pixel value correlation characteristic in a frame; and a decoding unit configured to perform repeated decoding by a belief-propagation method based on a first log-likelihood ratio and a second log-likelihood ratio to estimate the non-key block before the coding process, the first log-likelihood being obtained from the non-key block, and the second log-likelihood ratio being obtained from the key block and the characteristic information.

The present invention achieves a reduction in the size of a device by acquiring a plurality of images in different position without shifting microlenses (MLs) of an one imaging element while suppressing shading and crosstalk. Provided is an endoscope image-acquisition device including: an objective optical system that forms two subject images in parallel; and an imaging element that has a plurality of MLs arrayed at an entrance side from the objective optical system and in which pixels are allocated to the respective MLs, wherein the centers of light-sensitive portions at the pixels are displaced with respect to the optical axes of the MLs such that displacements therebetween are gradually increased from the center portion of the imaging element toward peripheral portions thereof; the position of an exit pupil of the objective optical system is closer to an object than an imaging position of the objective optical system is; and conditional expression (1) is satisfied. Here, is an angle formed by a chief ray at a horizontal maximum image height and an optical axis, H is a chief-ray correction amount (angle) for the ML at the horizontal maximum image height (H) from the center portion of the imaging element, and D is a chief-ray correction amount (angle) for the ML at a distance D from the center portion of the imaging element. The distance D is the distance between the center portion of the imaging element and the point of intersection between line drawn toward the center portion of the imaging element at a degrees from the position of the exit pupil of the objective optical system and the imaging element.
