Abstract: Four infrared LEDs and two photodiodes PD are arranged below a lower side of a display surface in the order of an LED1, a PD1, an LED2, an LED3, a PD2, and an LED4. A detection signal A1 of the PD1 when the LED1 emits light, a detection signal A2 of the PD1 when the LED2 emits light, a detection signal A3 of the PD2 when the LED3 emits light, and a detection signal A4 of the PD2 when the LED4 emits light are used to estimate a reflection generation position in the left-right direction, and a threshold Th is set such that the threshold Th increases when the reflection generation position is on the left side, which is a driver's seat side. If the maximum value of A1, A2, A3, and A4 exceeds the threshold Th, the approach of the user's hand is detected.

Abstract: A projection apparatus for use with a movable body is provided. The projection apparatus includes a parking controller configured to cause the movable body to automatically move to a parking space, and a projector configured to project light onto a road surface in vicinity of the movable body. When the parking controller causes the movable body to automatically park in the parking space, the projector projects the light onto the road surface located within a predetermined distance from the movable body.

Abstract: A display device has a first elastic member and a second elastic member between an outer support member and an extension portion outside an image display area of a front panel. The second elastic member is disposed at the position closest to an operation portion provided on the front panel in three directions. An elastic member pressing area is provided on a lower support plate of the outer support member. The second elastic member has a high compression ratio in the front-back direction, so the second elastic member acts as a pressure resistive portion. When the front panel is pressed with a finger in the operation portion, the strain of the front panel can be suppressed to a minimum due to a pressure resistive force.

Abstract: An image processing apparatus includes a memory, and a processor coupled to the memory and configured to obtain an image of a first camera disposed on a vehicle such that an imaging range of the first camera includes a portion of a vehicle body and images of a second and third cameras that image an area of a blind spot caused by the portion of the vehicle body, combine a blind spot image corresponding to the area of the blind spot in the image of the second camera with the image of the first camera, obtain three-dimensional information of a rear vehicle with stereo vision of the second and third cameras, and store rear vehicle shape information, wherein the processor determines three-dimensional information corresponding to a portion of the rear vehicle, and combines the blind spot image with the image of the first camera using the determined three-dimensional information.

Abstract: An active noise control unit generates a noise canceling sound of a single frequency that cancels engine sound heard by an occupant and outputs the noise canceling sound to a speaker through an amplifier. A second harmonic detector and a third harmonic detector detect a magnitude of a harmonic component of the noise canceling sound included in sound collected by a microphone. A controller controls a frequency of the noise canceling sound generated by the active noise control unit to a fundamental frequency of the engine sound based on a rotation frequency of the engine, and in addition, causes an output level control unit to control a level of the noise canceling sound to be output to the amplifier so that the level of the noise canceling sound becomes higher when the magnitude of the harmonic component exceeds a predetermined threshold value.

Abstract: When a gesture operation of a hand moving close to a display from left to right is performed, the return movement of the hand to the left side due to reflection by the wrist or the like may be detected. A detection control unit detects the approach of the hand to the display and notifies a data processing device of non-detection of hand approach when the amount of movement of the hand in the right direction starts to decrease after exceeding a threshold value. The data processing device accepts the right-moving gesture operation to perform a predetermined process when the amount of movement exceeds the threshold value.

Abstract: In a first state before a first event is detected, a determination unit of a press detection apparatus prevents a definitive value from increasing steeply when the pressing force has increased steeply, and decreases the definitive value steeply when the pressing force has decreased steeply. In a second state after the first event is detected and before a second event is detected, the determination unit prevents the definitive value from increasing steeply when the pressing force has increased steeply, and prevents the definitive value from decreasing steeply when the pressing force has decreased steeply. This reduces the possibility that the definitive value increases steeply in the first state and increases and decreases steeply in the second state even under vibration.
