摘要： An auto-focus (AF) camera enables AF operation with high speed and enhanced accuracy. The AF operation encompasses step-scanning the focus lens of the camera from the closest focal position to infinity, or vice versa. In one embodiment, the steps in the step-scanning are made smaller around a position judged to be close to the focus position, and the steps are made larger at other positions.

摘要： A digital camera having small time lag for recording the object after releasing a shutter by employing less movable parts, and by employing an image sensor for other purpose as well as actual forming picture image for recording the object is provided. According to one aspect of the present invention, a digital camera includes an image sensor having a plurality of two-dimensionally arranged pixels capable of selectively reading out signals from desired pixels and capable of adding signals of at least two pixels prior to getting the output from the image sensor, a first processor for processing outputs got from the individuals of the pixels of the image sensor to form a picture image of an object of the camera and a second processor for processing the added signal of the image sensor for light metering of the object. In the digital camera according to the present invention, by using an image sensor capable of selectively reading out signals from desired pixels and capable of adding signals prior to getting the output from the image sensor, signals from respective pixels are read out while processing picture image forming, and the output is got from the image sensor after signals from respective pixels within light-metering area are added while processing light metering. Accordingly, calculation for light metering can be processed quickly and a circuit for processing signals output from the image sensor can be simple. As a result, power savings as well as cost savings can be realized.

摘要： A film scanner generates and stores data for display on a display monitor of a host Computer. A user can use the film scanner and the host computer to view thumbnail images recorded on a film roll and to verify, create, or adjust information recorded on the film roll. The information recorded on the film roll includes data regarding a) the film roll, b) images on the film roll, and c) parameters for printing the images. In particular, the data includes selections of film image frames for which duplicate prints are desired, as well as information regarding the type and characteristics of the film and shooting conditions for each exposed frame of the film. The film scanner can record data onto, and read is data from, magnetic regions of the film. The film scanner can also read bar code information recorded on the film.
