摘要： Data on inspection, diagnosis, repair and operation histories are entered in a plant-maintenance apparatus for equipment that constitute a plant to be maintained. Failure-event tree breakdown is performed on failures to be expected for the equipment. Unreliability is predicted of at least one starting item in the failure-event tree breakdown. Unreliability of each item in the failure-event tree is calculated based on a failure unreliability function. Unreliability and a cost of recovery from each failure event in the failure-event tree are multiplied and results of the multiplication are accumulated in accordance with the tree breakdown to obtain a recovery cost. Preventive maintenance expenses are calculated for preventing failure events. Maintenance timing and technique are decided through comparison between the recovery cost and the preventive maintenance expenses.

摘要： There is provided an image processing apparatus, an image display and an image processing method which are capable of preventing an unnatural change in image quality due to image processing. A luminance distribution detecting circuit detects a luminance distribution as the histogram distribution of YUV signals. A gain limiter levels out by limiting the frequency of the luminance histogram to a frequency threshold or less so as to reduce the concentration of the distribution on a specific luminance level segment. Then a γ correction circuit in the image processing section performs image processing (contrast control) on the YUV signals through the use of the luminance distribution leveled out.
