Abstract: An information processing apparatus (10) includes a test pattern generation unit (17). The test pattern generation unit (17) generates a test pattern in which appearance of an image element indicating a positional relationship between a viewer and a viewing area continuously changes depending on a viewing position.

Abstract: An information processing apparatus (100) includes: a calculation unit (163) that calculates an index value related to display of stereoscopic image content including a stereoscopic image based on a relative position of a viewer with respect to a position of a display unit (150) that displays the stereoscopic image; and a display control unit (164) that controls display processing performed by the display unit (150) based on the index value calculated by the calculation unit (163).

Abstract: An deviation E between a setting value SV and an actual phase value PV in a controller is integrated, and the resulting integrated value S is compared with a predetermined threshold D for detecting a malfunction. Checking a change in setting value SV, checking an increase or a decrease in deviation E and comparison with the absolute value .vertline.E.times.S.vertline. are made to ensure stability against fluctuations and rapid detection of a malfunction.

Abstract: The present invention relates to a plant fault diagnosing system for diagnosing the operating conditions of the plant, for example, change in the physical quantity or whether any fault is present in each of the instrumentations or not. This system makes reference and makes directly comparison the process data of the plant or a diagnosing pattern processed by treating the process data in a predetermined process with a predetermined information for detecting showing the symptom of an abnormality or a predetermined reference value. When any deviation from a predetermined allowable range or coincidence of the patterns is detected, it determines that there is any abnormality in the plant, and issues an alarm to, for example, an operator.
