Abstract: A distance measurement apparatus (10) is an apparatus that causes a light receiving unit (180) to detect pulsed-light, which is emitted from a light source (14) and reflected by a target object (30). The distance measurement apparatus (10) includes an estimation unit (121). The estimation unit (121) estimates a peak position of the pulsed-light by using a saturation waveform that is a reception light waveform which is generated by the light receiving unit (180) that receives the pulsed-light and in which a reception light signal is partially saturated. Here, the estimation unit (121) specifies a temporary peak position by using a plurality of data points including a start point of the saturation in the saturation waveform. Further, the estimation unit (121) specifies a correction parameter based on a saturation width of the saturation waveform. The estimation unit 121 estimates the peak position of the pulsed-light by correcting the temporary peak position by using the specified correction parameter.

Abstract: A brightness level frequency indicated on a frame basis by an input video signal is accumulated in decreasing order or increasing order of the brightness level so that an accumulated brightness level frequency is calculated for every brightness level. The brightness level corresponding to the accumulated brightness level frequency smaller by a predetermined value than any one of the accumulated brightness level frequencies indicated as maximum is regarded as an effective maximum brightness level. Based on this effective maximum brightness level, the number of sub-fields is determined for assignment to each different brightness segment region. With such a configuration, the resulting display device can lead to favorable halftone representation without causing viewers to feel something is wrong no matter what type of display images.

Abstract: An image processor of an image processor system acquires outputted image data from an image-data output unit, and generates first quality-adjusted image data and second quality-adjusted image data each of which has been processed under a different quality adjustment condition. The image processor controls a display to display in a display area a first time-division-comparison image having a first quality adjusted image based on the first quality-adjusted image data and a second time-division-comparison image having a second quality-adjusted image based on the second quality-adjusted image data in an alternately-switching manner. With this arrangement, the first and second quality-adjusted images can be displayed without reducing a scale of the entirety. Thus, a user can view the images processed under different quality-adjustment conditions alternately in the same size as the actual size.
