In a voice mode, when a shutter button of a camera is fully depressed, first and second switches are turned ON, recording of voice starts. The shutter button is released. When the shutter button is half depressed after the shutter button is released the recording of the voice is stopped. Since the recording of voice is performed between when the shutter button is released and when it is depressed half, no mechanical sound is recorded.

Camera and computer program

In a digital camera, a pre-measuring device obtains color temperature information according to external light in a preliminary exposure. A white balance control value is then determined. The white balance is subsequently adjusted when a strobe light is generated. A regular exposure is thereafter made using the strobe light and the image is recorded for future processing.

Two-pass image processing method and apparatus using virtual estimation

In each optional area of an object to be photographed, image data obtained when a strobe (10) flashes a light and a CCD (3) is exposed to light from the object is compared with image data obtained when the CCD (3) is exposed to light from the object without flashing a light from the strobe by a data processing section 6. A CPU (12) then determines how much the light of the strobe contributes to photography in the each area which has been compared. After that, the CPU (12) suitably selects either a white balance control value given when the strobe does not flash a light or a predetermined white control value given when the strobe flashes a light and performs final white balance control. Both of the values are determined based on sensor data transmitted from a color measuring sensor (9) or based on an image signal transmitted from the CCD (3).
