    Abstract: Disclosed are an apparatus and a method for detection of foreign substances in a depth sensing system. In one embodiment, a depth sensing device includes a light source to emit light, an image sensor and a processor. The image sensor receives through an optical component the light reflected by environment of the depth sensing device. The image sensor further generates a depth map including a plurality of pixel values corresponding to distances between the depth sensing device and the environment. The processor detects a blurred portion of the depth map due to a presence of a foreign substance on the optical component. The processor may further cause outputting a user alert of the presence of the foreign substance on the optical component.

    Abstract: In order to measure a measurement target on a PCB, height information of the PCB is acquired by using a first image photographed by illuminating a grating pattern light onto the PCB. Then, a first area protruding on the PCB by greater than a reference height is determined as the measurement target by using the height information. Thereafter, color information of the PCB is acquired by using a second image photographed by illuminating light onto the PCB. Then, the first color information of the first area determined as the measurement target out of the color information of the PCB is set as reference color information. Thereafter, the reference color information is compared with color information of an area except for the first area to judge whether the measurement target is formed in the area except for the first area.

The method controls each of the CCD cameras to capture a digital image from a measured part that is placed near the CCD cameras, obtains the digital image of the measured part from each of the CCD cameras in a predefined order, and obtains a binary expression from the digital image of the measured part. When the measured part is placed in a correct position on the platform, the method further obtains three points from an upper boundary of the measured part in the binary expression and another three points from a lower boundary of the measured part in the binary expression, and calculates width of the measured part according to the obtained six points.

The image is integrated for improved resolution with a camera in front of the microscope screen or with a digitizer coupled to receive video signals from the microscope. The first image is digitized and stored in a first channel of an RGB digitizer board and displayed on a display screen. A second image is obtained in the same way and is digitized and stored in a second channel of the RGB digitizer board and displayed on the display screen. The remaining channel of the RGB digitizer board is coupled to receive live images. The resulting combined image appears as a black and white image so long as the images are aligned. Any differences between the three images will appear conspicuously in color. The input logic levels to the integrated circuit are changed.

  • Patent number: 5441047
    Abstract: An ambulatory (in the home) patient health monitoring system is disclosed wherein the patient is monitored by a health care worker at a central station, while the patient is at a remote location. The patient may be a person having a specific medical condition monitored or may be an elderly person desiring general medical surveillance in the home environment. Cameras are provided at the patient's remote location and at the central station such that the patient and the health care worker are in interactive visual and audio communication. A communications network such as an interactive cable television is used for this purpose. Various medical condition sensing and monitoring equipment are placed in the patient's home, depending on the particular medical needs of the patient. The patient's medical condition is measured or sensed in the home and the resulting data is transmitted to the central station for analysis and display.

  • Patent number: 5315384
    Abstract: A color line scan video camera (50) for inspecting articles (18) includes a prismatic beam splitter arrangement (52) that receives a wide spectrum of visible light from a variable magnification objective lens arrangement (54) to provide improved multi-color inspection capability. The prismatic beam splitter separates the light received from the scanned articles into three preselected spectral bands of light, each of which is imaged upon a different charge-coupled device line scan sensor that generates a corresponding color component video signal. The light transmission characteristics of the lens are "color-corrected" to transmit uniformly the light received from the scanned articles.

  • Patent number: 4652916
    Abstract: An image pick-up device for picking up the image of an object having different degrees of brightness, ranging from a low degree to a high degree. The device includes a light source for irradiating the object, an image pick-up unit for picking up an image of the object, and an optical system disposed between the object and the image pick-up unit for forming the image of the object on the image pick-up unit. A discrimination circuit designates a region of high brightness in the image of the object picked-up by the image pick-up unit, and a detection circuit detects the brightness level of a designated region of high brightness.
