Abstract: A mobile terminal includes a memory, and a processor coupled to the memory, wherein the processor executes a process comprising acquiring a frame with taking a photograph, acquiring document image data of a document from the frame, detecting shine on the document image data, determining whether the shine is equal to or smaller than a shine baseline, and acquiring a frame with retaking a photograph when the shine is neither equal to nor smaller than the shine baseline.

Abstract: An image processing system, an imager, an area detection method, and a computer program easily and highly accurately detecting an area where a target object exists in an image acquired by imaging the target object are provided. The image processing system includes a projector for projecting a projection image having a stripe pattern or a grid pattern toward a target object, and an imager for imaging a target object on which the projection image is projected, and the imager includes an input image obtaining module for obtaining an input image acquired by imaging a target object on which the projection image is projected, a height information calculator for calculating height information of each pixel in the input image by using the input image, and a target object area detector for detecting a target object area where the target object exists in the input image, based on the height information of each pixel in the input image.

Abstract: According to the present disclosure, an image-processing apparatus identifies for each gradation value a connected component of pixels of not less than or not more than the gradation value neighboring and connected to each other in an input image, thereby generating hierarchical structure data of a hierarchical structure including the connected component, extracts based on the hierarchical structure data a connected component satisfying character likelihood as a character-like region, acquires a threshold value of binarization used exclusively for the character-like region, acquires a corrected region where the character-like region is binarized, acquires a background where a gradation value of a pixel included in a region of the input image other than the corrected region is changed to a gradation value for a background, and acquires a binary image data of a binary image composed of the corrected region and the background region.

Abstract: A bar code scanning apparatus in which the visual field of a lens system is extended as outwardly exceeding the width of an opening of a case body in which the apparatus is housed, such that a bar code wider than the width of the opening can be scanned. A bar code wider than the width of the opening can be scanned with the opening coming in contact with the bar code. Thus, a wide bar code can be scanned without the bar code scanning apparatus increased in width and length.

Abstract: A fiberscope having a covering tube, an image fiber for transmitting picture images and equipped with an optical system at its tip end for focusing an image of an object to be observed, and light guides for transmitting light and placed along with said image fiber. The image fiber and the light guides are enclosed in said covering tube. A plastic body formed of substantially transparent material and convex shape is provided at front ends of the light guides. Liquid guide passages are also provided between an inner peripheral surface of the covering tube and outer peripheral surfaces of the image fiber and the light guides. Outlet ends of the light guides are arranged in positions substantially symmetrical with respect to an output end of the image fiber, and outlet ends of the liquid guide passages are arranged in positions substantially symmetrical with respect to the outlet end of the image fiber.

Abstract: An optical fiber sensor is composed of an outer portion generally in the form of a tube which constitutes an illumination light transmission path. Inside the tube is formed or inserted an image path for directing image light back to an observation point. A longitudinal hole may be formed beside or surrounding the image path for conducting a fluid to the observed location. The sensor is especially suitable for medical image catheter or endoscopic usage.

Abstract: A monitoring device for monitoring an interior conduit wall includes a plurality of sliding members each resiliently urged by equal amounts away from the device body toward the conduit wall, so that the device can be used in conduits of different diameters while always remaining substantially centered within the conduit.

Abstract: A microlens for use with an optical fiber or the like. It comprises a single lens having a diameter of about 0.5 mm. It provides an ideal combination of the length of the lens with the refractive index of its opposite surfaces for a minimum curvature of field.

Abstract: A protective lid is provided in front of an image-forming lens mounted on the forward end of a picture image transmission line which comprises plural optical fibers bundled in alignment to be remotely controlled from the back end of the transmission line for opening/closing so that the image-forming lens may be protected from particles, vapor or poisonous gas when the transmission line is used in such atmosphere, thereby preventing deterioration of the quality of picture images to be formed.
