According to one embodiment, an interpolated frame generating method of generating a new interpolated frame to be inserted between sequential frames by using a plurality of input frame images, comprises detecting a motion vector of an object in frame images by block matching processing between the input frame images, determining certainty of the motion vector detected in the detecting, and determining a certain motion vector and an uncertain motion vector based on a result of the determining, and generating the interpolated frame by using the motion vector detected in the detecting. The generating is generating the interpolated frame by setting a value of a motion vector determined as an uncertain motion vector in the determining to zero.

There is provided a flat-panel video display apparatus, which improves a brightness of a screen at low price and low power consumption, and reduces flicker. When a scanning line is successively driven by several lines, the apparatus is provided with means for supplying a first voltage to a driven main scanning line, and for supplying a second voltage lower than the first voltage or third voltage having a drive period shorter than a drive period of the main scanning line to simultaneously drive other sub-scanning lines.

A method of drilling a well by utilizing AE/MA measurement which has the steps of monitoring an AE wave emitted at the periphery of the well, and drilling the well without lost circulation by providing lost circulation preventing means in the well if the energy of the AE wave emitted at the periphery of the well increases. Thus, the method can confirm a lost circulation layer, i.e., the size, the place and the direction of the underground crack to further determine whether further drilling is necessary or not.

A method of collecting geothermal steam using Acoustic Emission Microseismic Activity (AE/MA) measurement includes the steps of (a) surveying an AE wave emitted in subsurface cracks to obtain the size of a water permeable geothermal reservoir by analyzing the AE wave, (b) further surveying the AE wave emitted in and around the periphery of the geothermal reservoir, (c) operating the wellhead valve of the geothermal well connected with the geothermal reservoir, thereby extending or preventing the extension of the geothermal reservoir in accordance with the information obtained in step (a) and/or step (b), thereby stably obtaining a predetermined quantity of steam of high quality. Thus, the method can stably obtain geothermal steam of high quality by accurately surveying or monitoring subsurface cracks by an AE measurement technique and propagating the subsurface cracks or suppressing the propagation of the cracks.

A lateral object that exists on a side of the vehicle is detected. When an estimated later-arriving lateral position reaches a predetermined threshold value under the condition in which the lateral object is detected, a lane change of the vehicle in a direction to a side of the lateral object is suppressed. When detecting that the vehicle moves laterally in a direction opposite to a side of a side vehicle, an avoidance flag is set to Fa=1. Subsequently, when the vehicle starts a lateral movement in a direction to the side of the side vehicle, a return flag is set to Fr=1. When the return flag is set to Fr=1 in this way, a suppression flag is set to F=0 until a setting time elapses, then the suppression of the lateral movement is forbidden.

According to one embodiment, an image processing apparatus includes a resolution increasing module and a moving-image improving module. The resolution increasing module that performs, on receipt of a first video signal with first resolution, super resolution conversion on the first video signal to obtain a second video signal with second resolution that is higher than the first resolution by estimating an original pixel value from the first video signal and increasing the pixels. The moving-image improving module that increases the frame rate of the second video signal after the super resolution conversion.

According to one embodiment, an interpolation frame generation apparatus generates an interpolation frame image to be inserted between continuous frame images. The interpolation frame generation apparatus includes a motion vector detection module and a generation module. The motion vector detection module is configured to execute block matching processing in each of a plurality of blocks included in the continuous frame images and specify one motion vector on an interpolation frame. The generation module is configured to, for an interpolation block in which the motion vector detection module specifies one motion vector, generate an interpolation frame image based on the motion vector, and for an interpolation block in which the motion vector detection module does not specify one motion vector, generate an interpolation frame image based on the frame image containing no motion vector component.
