An image signal processing apparatus capable of detecting a black band region included in an input image signal in a shorter time is provided. The image signal processing apparatus may include a measuring means for measuring in a unit frame period whether each pixel in a designated measurement region of an input image signal has a signal level less than a threshold value; and a black band detecting means for detecting a black band region included in the input image signal on the basis of a measurement result from the measuring means.

The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of thewindshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. Theabrupt thermal gradients during bending, caused by the heat absorbing black frit, result in a high level of distortion in the camera field of view. The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by creating an obscuration after heating and bending the glass by removing a portion of the plastic interlayer glass in or near the camera field of view (camera obscuration) or / and in the edges of the windshield (black band) and replacing it with an inlay made of a substantially opaque plastic or other suitable material in or near the camera field of view (camera obscuration) or / and in the edges of the windshield (black band) rather than printing and firing an enamel frit on the glass. This results in a laminate having superior opticalquality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.

A display apparatus includes an orientation detecting portion, a receiving portion and an image processing portion. The orientation detecting portion detects an orientation of an upper part or a lower part of a display screen of a display portion. The receiving portion receives an image signal transmitted from a source device and state information (information showing an orientation of an upper part or a lower part of the transmission image indicated by the image signal and presence / absence of black band parts). The image processing portion applies, to the transmission image, rotation processing such that the orientation of the upper part or the lower part of the display screen coincides with the orientation of the upper part or the lower part of the transmission image, scaling processing, and / or black-band processing for adding or removing black band parts, according to a detection result of the orientation detecting portion and the state information.

A projection system and method for forming color images are provided. In this method, the rise time and fall time of the imaging signal are changed required to obtain multiple color bands formed on the light valve. First, install at least one filter with slits. Next, the incident light is rolled by converting the rotation of the rolling unit into a linear motion of the incident light passing through the lens element of the rolling unit. The light beam emitted from the light source is then separated according to color using a color separator containing a plurality of color-selective mirrors, each of which transmits the incident beam as a beam of one wavelength and reflects a beam of another wavelength. Then, multiple color beams separated by the color separator and rolled by the rolling unit are incident on the corresponding color areas on the light valve, thereby generating multiple color strips. Then a black band is formed between adjacent color bands by controlling the distance between adjacent color selection mirrors or controlling the width of the slit.

The invention discloses a waveform extraction method of a medical instrument video information extractor, which includes the following steps: setting a black belt detection area in the waveform detection area; two black belt detection areas as a processing frame, in one processing in one processingThe entire waveform is reasonably segmented in the frame, and the number of frames is averaged one by one; each processing frame is processed to record once.The advantage of the present invention is that it can well eliminate the impact of random noise, make the waveform distortion less, and record the waveform data with the minimum amount of data, which facilitates the network transmission, storage and query of the data.

Disclosed is a method of manufacturing an optical film wherein a failure due to foreign matters, a black band while the film is rolled, and blocking never occur in the surface of the film, eliminating wrinkles and flaws. The method of manufacturing the optical film comprises: a process of clamping a member comprising a plurality of projections onto both side edge sections of the long film in the width direction, thereby knurling the side edge sections by irregularity; and a process of taking up the film. In the process of knurling, the height of projecting portions formed by a film member clamped away by the projections when the projections are clamped onto the surface of the film is restricted by a flat portion configuring the base of the projections, so that the height of the projecting portions is determined height.
