A display control device (1) according to the predetermined includes a housing (11) configured to house a display (13) on which a video image taken by a camera (15) is displayed and be able to be displaced independently of the display (13), a sensor (12) configured to detect a displacement of the housing (11), and a control unit (14) configured to control a video image displayed on the display (13) so that a video image in a direction corresponding to a direction of the displacement of the housing (11) detected by the sensor (12) is displayed on the display (13).
摘要:
Conventional echo cancellation devices have a problem that an echo signal cannot be fully attenuated. An echo cancellation device outputs a first voice signal in which frequency components equal to or higher than a target frequency are suppressed, and acquires an acoustic signal (S2) including a frequency component higher than the target frequency. The echo cancellation device includes an echo signal reduction processing unit (18) that generates a transmitting signal in which an echo signal component is reduced from the acoustic signal (S2); and a filter coefficient update determination unit (17) that instructs the echo signal reduction processing unit to update the filter coefficient when the output voice signal (S1) corresponds to a voice section and the acoustic signal (S2) includes the echo signal component. The filter coefficient update determination unit (17) calculates a feature value of the acoustic signal (S2) and instructs to update the filter coefficient when a difference between a first feature value of a frequency band equal to or lower than the target frequency and a second feature value of a frequency band higher than the target frequency is equal to or greater than a preset update determination threshold.

A waveform correction processor (10) corrects the waveform of a first digital audio signal (a CD signal, for example) having a first sampling frequency. A bit depth and sampling frequency converter (50) converts the first digital audio signal with the waveform corrected by the first waveform correction processor to a second digital audio signal (a high-resolution digital audio signal, for example) having a second sampling frequency, which is higher than the first sampling frequency. The waveform correction processor (20) corrects the waveform of the second digital audio signal.

A rearview mirror with a display function (1) includes a display panel (30) that displays a picture of a rear camera (51) of a vehicle, and a half mirror (22) provided in a display surface of the display panel (30). A motion sensor (40) performs motion detection. A switching control unit (108) performs processing of switching a mode to a display mode, in a motion detection result in any direction of directions detected by the motion sensor (40), when the rearview mirror with a display function (1) functions as a mirror mode, and processes the motion detection detected by the motion sensor (40) as a moving instruction of a display range to each of the detected directions, when the rearview mirror with a display function (1) functions as the display mode.
摘要:
A mask information generator 4 carries out the following processing: (1) defining lines which become respective sides of a polygon of which three or more points on a display screen designated by user's operation become vertices; (2) calculating a value of a coordinate in a vertical direction on each of the lines which has a value of a coordinate in a horizontal direction of each pixel designated by a counter which designates a coordinate of each pixel in an image signal based on a synchronization signal thereof; and (3) comparing a value of the coordinate designated by the counter in the vertical direction of each pixel with the calculated value of the coordinate on each of the lines, to determine whether or not each pixel in the image signal is included in a mask region which is a region within the polygon surrounded by the lines. A masking unit 5 carries out masking using a mask image with respect to each pixel included in the mask region.

An image display apparatus (100 or 800) includes a laser light source unit (164), a scan mirror unit (170), a rendering control unit (132), a detecting unit (122 or 145), and an output adjusting control unit (134). The rendering control unit (132) controls the laser light source unit (164) in such a way that a display image is rendered in a range smaller than a scan range of the scan mirror unit (170) based on input display image data. The detection unit (122 or 145) detects a range to be a reference for setting a laser beam output position for adjusting an output of the laser beams based on the display image data. The output adjusting control unit (134) controls the laser light source unit (164) in such a way that the laser beams for adjusting an output of the laser beams are output at a position outside the range where the display image is rendered in the scan range of the scan mirror unit (170), and the position is based on the range detected by the detecting unit (122 or 145).

Provided are an operation input device, an operation input method, and a program for suppressing an influence of a disturbance and improving gesture detection accuracy. Included are: infrared irradiation means configured to radiate infrared; capturing means configured to detect the infrared to capture an image; luminance calculating means configured to calculate, in a captured image which is the image captured by the capturing means, a luminance difference between luminance of a first area irradiated with the infrared by the infrared irradiation means and luminance of a second area arranged outside the first area; infrared control means configured to adjust an irradiation intensity of the infrared to be radiated from the infrared irradiation means such that the luminance difference calculated by the luminance calculating means becomes a predetermined target value; image processing means configured to detect a shape of an indication object from the captured image; determination means configured to determine an operation by the indication object from the shape detected by the image processing means; and command means configured to make a device to be operated perform a function corresponding to the operation determined by the determination means.

A diagnosis assisting apparatus includes a display, imaging units (202 and 204) for imaging a subject, a line of sight detecting unit (351) for detecting a line of sight direction of the subject from a picked-up image imaged by the imaging units (202 and 204), a point of view detecting unit (352) for detecting a point of view of the subject in a display region on the display based on the line of sight direction, an output controller (354) for displaying a diagnostic image including a natural image and a geometrical image similar to the natural image on the display, and an evaluation unit (359) for evaluating a degree of developmental disorder of the subject based on the point of view detected by the point of view detecting unit (352) when the diagnostic image is displayed.
