摘要： A focus detecting device for a camera utilizing auxiliary illumination, comprises a sensor for detecting the image of a photographic object, a first light emitter for projecting a first auxiliary light toward the object, a second light emitter for projecting a second auxiliary light toward the object. The second auxiliary light illuminates a smaller area than the first auxiliary light. The first and second light emitters are selectively driven in response to brightness of the object, thereby to produce a contrasty light image onto the object.

摘要： An image processing apparatus permits easy changing of the file name of an image file created by an image taking apparatus. A personal computer serving as the image processing apparatus is fed with an image file created by a digital camera, and replaces a first character string included in the file name of the image file with a second character string. The first character string consists only of characters usable in a file name on the digital camera, and the second character string consists of characters selected among all the characters usable on the personal computer. The first and second character strings are entered via a keyboard, and are stored, in the form of a look-up table that lists their correspondence, in a hard disk.

摘要： An electronic camera adopts an image pickup and optical system of a mirror scan type in which a mirror for scanning is disposed at a forward side of a taking lens. A line image sensor relatively scans an object while rotating the mirror to perform photographing. When controlling the exposure, the taking lens is moved synchronously along with rotation of the mirror to adjust the focal position thereof each time a slender sub-image of the object is picked up by the CCD. Driving the taking lens to focus the sub-image each time of scanning the sub-image enables picking up an entirety of the object image perfectly in a focused state.

摘要： An image taking apparatus includes an image sensor which picks up an image of a photographic object and a selector which selects a first photographing mode or a second photographing mode and a controller. The second photographing mode is a mode for composing a plurality of picked-up images to create a composite image. The controller makes the image sensor pickup a photographic object image on the first photographing condition when the first photographing mode is selected by the selector, and makes the image sensor pick up a plurality of images of photographic objects on the second photographing condition different from said first photographing condition when the second photographing mode is selected by the selector.
