摘要： A bar-code reader has an optical scanner (2) which optically scans a bar code (1) to obtain signal strength of light reflected from black bars and white bars of the bar code (1). An extracting unit (5a) then extracts edge data, which includes a plurality of edges and the signal strength of which changes corresponding to a change from a black bar to a white bar and vice versa, and an edge-emphasizing unit (5f) emphasizes edge data of an edge that satisfies a predetermined condition. A judgment unit (5h) is then used to make a ternary judgment of each edge based on the edge emphasized to obtain a ternary result, and a decoder (5i) decodes bar-code characters from the ternary result.

摘要： A bar code reader (100) is arranged to communicate with a host apparatus (200). The bar code reader includes a read unit that reads a bar code (50) attached to an article, and outputs bar code information corresponding to the read bar code; a term information acquisition unit that acquires term information included in the bar code information; and a term expiration check unit that checks whether the shelf life of the article has expired based on the term information. A notification unit notifies that the shelf life of the article has expired upon determination by the term expiration check unit to the host apparatus (200). By performing its own expiration check, the bar code reader reduces the load on the host apparatus.

摘要： A liquid crystal panel (22) includes an iris unit (22a) for limiting the incident range of light from an object (27) to be shot, and a filter unit (22b) for assigning a exposure energy distribution varying with the position to incident light whose incident range is limited by the iris unit (22a). The control unit (23) controls the ON time and the OFF time of each pixel of the liquid crystal panel (22), and then a low pass filter operation on the captured image as an image processing can be optically replaced.

摘要： The optical path of the light having spread at each point of an object to be shot is limited by an iris unit (22a) of a density filter (22). Since the density filter unit (22b) has a desired transmittance characteristic, the amount of the light passing through the density filter unit (22b) continuously changes from the center of the luminous flux toward the periphery. After the luminous flux forms an image on the image forming surface, it spreads toward the light-receptive surface of an image sensor (24), and becomes an image spreading on the light-receptive surface in a predetermined range.

摘要： An image capturing apparatus illuminates an object and captures an image of the object using the reflected light from the object. The image capturing apparatus includes an image sensor 30 for capturing an image of the object by receiving reflected light, distance-measuring light-emitting devices 52 for irradiating the object with spot light, and a control circuit 90 for driving the distance-measuring light-emitting devices, detecting the spot light positions of the distance-measuring light-emitting devices from an image captured by the image sensor 30, and obtaining the distance to the object. The image sensor 30 provided for capturing an image of the object can be used as a photodetector device for distance measurement. With this, it becomes unnecessary to separately provide a photodetector device for distance measurement, which enables miniaturization of the image capturing apparatus, as well as cost reduction.
