Abstract: A portable terminal device or cellular phone includes a target setting section, a display unit, a focused-state determination section, and a recognition section. The photography-target setting section sets normal photography mode for photographing an image, and OCR mode for photographing a character or bar code. The display unit displays a photographed image, and positioning of an image as a photography target. The focused-state determination section is activated, and determines a focused state of a character or bar code photographed in the OCR mode. The recognition section recognizes the photographed character or bar code, the result of which is displayed by the display unit. Press of a confirmation button initiates a process to communicate with a communications target corresponding to the recognized result. A linking section may link recognition results to form a continuous string.

Abstract: It is possible to correct camera shaking even in an imaging device such as a camera-equipped mobile telephone having no sufficient ability for rapidly acquiring a plurality of images and a limited memory capacity. There is suggested an imaging device capable of correcting camera shaking by utilizing a small image such as a preview image and a target image to be obtained when a user of the imaging device clicks a shutter. The preview image has an appropriate exposure but has a high possibility that camera shaking has occurred. The target image is captured by insufficient exposure because of rapid shutter speed but the camera shaking is reduced. The image information on the target image is corrected by the image information on the preview image so as to obtain an image of reduced camera shaking and appropriate exposure.
