  • Publication number: 20210232259
    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.

  • Publication number: 20210227665
    Abstract: A plurality of infrared LEDs, e.g., four, and a plurality of photodiodes, e.g., two, are arranged side by side in interleaved fashion in the order of an LED1, a PD1, an LED2, an LED3, a PD2, and an LED4, and are arranged slightly ouside a side of the display surface. A threshold value Th is set so as to become small as max(Ei)/max(Aj) calculated from a detection signal of the PD1 when the LED1 emits light, a detection signal of the PD1 when the LED2 emits light, a detection signal of the PD2 when the LED3 emits light, a detection signal of the PD2 when the LED4 emits light, a detection signal of the PD2 when the LED1 emits light, and a detection signal of the PD1 when the LED4 emits light, and the approach of the hand of the user is detected when max(Aj) exceeds the threshold value.

  • Publication number: 20210195050
    Abstract: A proximity detection device detects the proximity of an object using a light emitting element and a light receiving element that receives reflected light of irradiation light from the light emitting element reflected by the object. A mirror is provided near the light emitting element to reflect part of the irradiation light emitted from the light emitting element toward an area at which the irradiation light from the light emitting element does not sufficiently arrive, and a mirror is provided near the light receiving element to enable reception of the reflected light from the light emitting element in a wide range.

  • Patent number: 6219043
    Abstract: A method and system in which a section of a previously encoded digital bit stream is replaced with another section of encoded video. In order to remove a section of encoded video, it is necessary to determine the beginning and ending points of the encoded video in the digitally encoded bit stream. The addresses of the beginning and ending points of the encoded data cannot be simply looked up but are calculated by summing the bits consumed by each picture, the number of bits of the sequence header of each picture, the number of bits of each Group of Pictures (GOP) header, and all stuff bits. In order to encode the video which is to be inserted in place of the removed video, a process is performed which prevents decoding artifacts from appearing. This is accomplished by determining the last P-picture before the edit point and using it as a reference frame for frames after the edit point.
