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.

An endoscope system computes a distal end position of the endoscope or a position of the desired imaging target. An image taken of the desired imaging target is recorded. A position of the desired imaging target is computed and recorded. A current image taken by the imaging unit is compared with the image of the desired imaging target already recorded. A first driving amount for driving the field-of-view adjustment mechanism is computed such that the desired imaging target is positioned on an axis of sighting of the imaging unit. A second driving amount for driving the field-of-view adjustment mechanism is computed in such a way as to include a center of the image of the desired imaging target. The field-of-view adjustment mechanism is driven from either one of the first driving amount or the second driving amount.

Provided is an endoscope system and a pixel correction method that are able to surely correct a blinking defective pixel in an image sensor. An endoscope system 1 includes: an illumination controller 33 that turns off a light source unit 31 in a predetermined cycle; a difference calculation unit 52 that calculates difference data between a dark image corresponding to image data output from an image sensor 244 during lights-out time when the illumination controller 33 turns off the light source unit 31 and a dark reference image preliminarily generated to detect a blinking defective pixel in which the electric signal irregularly changes; a blinking defective pixel detection unit 53 that detects a blinking defective pixel in the image sensor 244 based on the difference data calculated by the difference calculation unit 52; and a pixel correction unit 561 that corrects the electric signal output from the blinking defective pixel detected by the blinking defective pixel detection unit 53, by using electric signals output from neighboring pixels of the blinking defective pixel.


An ultrasonic observation apparatus includes a storage unit for storing a plurality of data sets including position information indicating a position of an observation point, the feature extracted by a computation unit for the observation point, image data generated by an image processing unit for the observation point, and parameters used for extracting the feature and generating the image data, a data selection unit for searching the data sets based on relative position information indicating a relative position between a patient and an ultrasound probe and selecting a data set meeting a predetermined condition, and an execution control unit for, when a data set meeting the predetermined condition is selected, causing the computation unit to re-extract the feature by use of the parameters included in the data set.
