摘要： PROBLEM TO BE SOLVED: To provide an imaging device capable of performing an image processing so as to obtain an appropriate image in accordance with the setting situation of an AF control. SOLUTION: When a continuous AF mode is set for lens driving to continuously hold a state of focusing an object, it is highly possible that the object is a moving object. When a one-shot AF mode is set to stop driving a lens when the state of focusing the object is achieved, on the other hand, it is highly possible that the object is a still object. When the continuous AF mode is set, in main imaging, edge emphasis processing B is performed with a relatively higher extent of emphasis in edge emphasis processing than edge emphasis processing A in the case that the one-shot AF mode is set.

摘要： PROBLEM TO BE SOLVED: To provide an electronic camera capable of attaining a high speed automatic focusing (AF) control and properly displaying a preview at the AF control.
SOLUTION: A CCD (charge couple device) imaging device for a digital camera 1 can select either a draft mode wherein comparatively many pixels are read and an automatic focusing mode wherein the pixels are read at a comparatively high speed. The digital camera 1 attains high speed AF by performing AF control on the basis of an image Gf read in the automatic focusing mode, detects the moving amount (vector) M of an object by utilizing the image Gf read in the automatic focusing mode, generates a display image Gh on the basis of the moving amount and an image Gb which has been read in the draft mode before the transition to the automatic focusing mode, and allows an LCD (liquid crystal display) or the like to display the display image Gh.

摘要： PROBLEM TO BE SOLVED: To enhance the dimming accuracy of a dimming controller where TTL automatic dimming and FM control are combined. SOLUTION: A camera CPU 301 controls dimming quantity by the TTL automatic dimming within the range of the emitted light quantity by the FM control. Parameter information being the error factor of the emitted light quantity by the FM control (information on a factor concerning the detecting accuracy of a subject distance on a lens 200 side, a factor changing illuminating quantity for a subject by the attachment of a diffuser on a flash side. A factor changing the arriving light quantity at a film surface by the attachment of an optical filter on the lens 200 side) is inputted in the camera CPU 301 by communication with the switch groups SSELF to SGNCM of a camera body 100, a lens CPU 204 in the lens 200, and the light emission control circuit 401 of an external flash 400. When the reliability of the emitted light quantity by the FM control is low based on the parameter information being the error factor, the camera CPU 301 decreases improper dimming by relaxing or releasing the restrictions of the dimming quantity by the TTL automatic dimming.
