Abstract: PROBLEM TO BE SOLVED: To improve the read performance of a code in simple device configurations. SOLUTION: A code read device 10 is provided with a one-dimensional scanner P and a two-dimensional scanner Q. When the code scan of a one-dimensional code is simultaneously performed by a one-dimensional scanner P and a two-dimensional scanner Q, the irradiation position of a light beam scanned by the one-dimensional scanner P is detected by a CPU 11 in an area image fetched from the two-dimensional scanner Q. Then the distance to the one-dimensional code is calculated on the basis of the detected irradiation position of the light beam, and the change setting of a parameter associated with the code read of the one-dimensional scanner P is performed according to the calculated distance. After the change setting of the parameter, the code scan is performed by the one-dimensional scanner P again, and the decoding of the read code is performed. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To easily check the image quality of an image of an object to be focused.
SOLUTION: In a digital camera 10, when a shutter key is half-pressed, focusing is performed based on a region within a focusing area frame R of image data captured by a photographing apparatus 16 to extract the feature point information of the object to be focused from the image data used for the focusing. When the image data are captured from the photographing apparatus 16 after the focusing, the position of the object to be focused is specified from the captured image data based on the extracted feature point information. When a confirmation key is pressed, an image at a position specified as a position of the object to be focused is displayed in a magnified manner on a display screen of a display device 15.
