A digital camera includes: an image sensor that captures an image of a subject and outputs an image signal; and a control device that engages the image sensor to capture an image at an exposure value having been set, makes a decision as to whether or not an overflow or an underflow deviating from a dynamic range of the image sensor manifests, calculates an exposure correction quantity with which the exposure value having been set is to be corrected in order to reduce the overflow or the underflow based upon results of the decision and engages the image sensor to capture a new image at an exposure value having been corrected in correspondence to the exposure correction quantity.

A digital camera has output ports that are connectable by cables to an HDTV television. The camera generates a slide show viewable on the television screen. The slide show involves a sequence of images stored on the camera and audio stored on the camera. The slide show is supplied to the television in the form of an HDTV resolution video stream and an accompanying audio stream. A user selects one of a plurality of scenarios for the slide show. The particular scenario determines how identified images will be presented. Using camera buttons, the user can stop and start the slide show and can move a pointer on the television screen. A standard EVJ file that defines the slide show in accordance with a scenario is generated by the camera. The file can be played on any rendering device that supports the EVJ functionality so as to recreate the slide show.

The digital camera comprises: an image-taking device for converting light from a subject to a video signal and outputting the video signal; an image processor which has a gain adjuster for performing gain adjustment individually for respective color information of R, G, B of the video signal outputted from the image-taking device, and an image data converter for converting the adjusted video signal outputted from the gain adjuster into image data; a displaying device for displaying the image data; a setting device; and a controller for controlling the gain adjuster to perform RGB color discrimination of the video signal and gain adjustment individually on the respective color information by a command from the setting device.

A digital camera is constituted of a camera body and a lens unit. The lens unit is removably attached to the camera body. When the lens unit is attached to the camera body, they are electrically connected through connection terminals. A nonvolatile memory in the lens unit previously stores a chart image that is obtained by capturing a resolving power chart representing image resolving power by a CCD. When an attachment detector of the camera body detects that the lens unit is attached to the camera body, the chart image is transferred into the camera body and is displayed on a LCD.

A lens module (20) is adapted for use in a digital camera. A lens module includes a lens barrel (21), a plurality of lenses including a first lens (22) and a second lens (23) and an aligning mechanism. The two lenses received in the lens barrel. The aligning mechanism an aligning mechanism configured to align respective optical axes of the first and second lenses with each othe. The aligning mechanism is disposed between the two lenses.

A wireless telecommunications terminal is provided comprising a digital camera and a processor. The digital camera is configured to take a digital photograph of an item showing a character string. The processor is configured to receive data of or relating to the character string read by an optical character recognition (OCR) reader in the digital photograph information, and to process said data.

A digital camera enabling a photographer to select representative frames reflecting his intentions, which captures both moving pictures and still images, and encodes moving picture data by frame correlation compression. The camera includes an image processing section that increases the number of I pictures in compressed moving picture data captured before, or before and after, a still image recording (SIR) instruction is received during moving picture acquisition. By this arrangement, continuous image data can be buffered for a fixed time period, and when a SIR instruction is given, this image data can be compressed and recorded as I pictures with the data being traced back for a fixed time period. As a result, image data further in the past by a fixed time period than the time at which the SIR instruction is given can be acquired as I pictures, enabling the user to select intended representative frames.

A processor-based system may be controlled using a digital camera. The digital camera can provide luminance and motion information which may be analyzed to determine whether to alter one or more of the power consumption state, the operation of system utilities, or the operation of a screen saver.
