Abstract: Method for detecting a surface flaw of an object using an electronic device includes requesting a detection device to control a camera unit to capture a current image of a test object placed on the detection device. The current image includes a sidewall image and a reflected image. The method obtains the current image, and detects whether the sidewall image has a surface flaw. When the sidewall image has a surface flaw, a rotation angle of the test object is determined based on the reflected image. The method obtains a standard sidewall image of a standard object stored in a storage device of the electronic device, based on the rotation angle, compares the sidewall image with the standard sidewall image, and determines and displays a position of the surface flaw on a sidewall of the test object based on the comparison.

Abstract: A vehicle-mounted camera device that is mounted on a vehicle and captures a surrounding image from which lights are collected by a lens, in which the lens is set so as to have the surface having a contact angle less than or equal to 100°, preferably less than or equal to 60° so that water attached on the surface is made into a form of a film. For this reason, the surface of the lens has high hydrophilicity, and if water droplets are attached when it is raining, the water droplets extend over the surface of the lens to form a water film. Thus, if mud or other attached matter is attached on the surface of the lens, it is possible to remove the attached matter without delay, and it is possible to always keep the surface of the lens in a clean state.

Further, source block size may be adaptively determined in a downsampled image layer and hierarchical motion estimation may be performed using the adaptively sized source blocks.

Abstract: A method of detecting an original arrangement of laboratory articles of a laboratory work station records reference digital images with a digital camera. An image is displayed and visible regions with characteristic features are selected by a user within an input device. Reference image sections and corresponding reference image parameter files are produced and stored. A current arrangement of laboratory articles is compared with a previously recorded original arrangement. Detection of the current arrangement occurred by recording current digital images with a digital camera and creating current image sections defined by X/Y parameters of the reference image parameter files from the current digital images. A computer-based comparison of the processed current image sections with the processed reference image sections occurred and an analysis of this comparison and the display of agreements, deviations and errors is found.

Abstract: With respect to an emitting side optical axis, which is an optical axis on a first surface, a sight line reference axis which is assumed as a sight line axis of the eyes of an observer extends in a slightly inclined direction. In particular, the emitting side optical axis with respect to the sight line reference axis is configured to approach the eyes from the outside (that is, a corner of the eyes) of the eyes. In addition, a long image in a vertical direction which is perpendicular to an alignment of the eyes rather than in the horizontal direction which corresponds to the alignment of the eyes, is displayed.

Abstract: Three-dimensional imagers have conventionally been constrained by size, weight, and power (“SWaP”) limitations, readout circuitry bottlenecks, and the inability to image in sunlit environments. As described herein, an imager can illuminate a scene with spatially and temporally modulated light comprising a viewpoint-invariant pattern. The imager can detect diffuse reflections from the illuminated scene to produce a first image. The first image is background-corrected and compared with respect to a known reference image to produce a depth image. The imager can perform in sunlit environments and has improved SWaP and signal-to-noise (SNR) characteristics over existing technologies.

Abstract: A video processing circuit includes a video generating unit for generating a video output stream, a data generating unit (e.g. graphic generating unit) for providing a data stream (e.g. graphical stream), and a communication interface circuit. The communication interface circuit has a mode provided for merging the video output stream and the graphical stream to transmit a first merged signal through a channel. In the mode, the communication interface circuit merges the video output stream and the data stream by increasing a working frequency of the communication interface circuit to increase bandwidths of the channel, using positions for transmitting a portion of video control signals in the video output stream to transmit the data stream, and compressing the video output stream. The communication interface circuit may have another mode provided for mixing the video output stream and the data stream to transmit a mixed video output stream through the channel.
