A digital camera comprises an image sensor for providing initial sensor image data and final sensor image data; a lens for exposing the image of a scene onto the image sensor; an exposure control system for adjusting an exposure level of a final image on the image sensor in response to a scene type; and a processor for processing the initial sensor image data to select one of a plurality of scene types, and to process the final sensor image data in response to the scene type.

Camera using preview image to select exposure

An imaging apparatus according to this invention comprises: an image capturing unit which performs continuous image capturing; a storing unit which stores a plurality of first images captured by the image capturing unit before a shutter button is pushed, and a plurality of second images captured by the image capturing unit after the shutter button is pushed; and a generating unit which generates a background image which is an image of a background of a dynamic body included in the first images and second images based on at least the plurality of first images.

Imaging apparatus, imaging method and computer program

In an image capturing apparatus, a hue shift is prevented. A digital camera has a gray level correction function. Image data obtained with a CCDis divided into a plurality of blocks and further has brightness data and color difference data converted in a brightness/color difference conversion section. When it is determined, based on the color difference data, that image data includes blue sky image or that chroma of the image data is high, an image processing exposure compensation adjustment/exposure correction amount calculation sectionsets an underexposure value, which is employed when capturing images with an exposure value being lower than a correct exposure value, to be smaller than a default value to prevent a hue shift caused by gray level correction performed by a gray level correction section

Image capturing apparatus for adjusting an exposure value that is set lower than the correct exposure value

To provide an auto white balance apparatus and a white balance adjusting method capable of performing more stable white balance adjustment. For every block, a characteristic pixel determination circuitdetermines a characteristic pixel from among a pixel group in a block and a light-source reflection determination circuitdetermines whether the typical value of a block reflects the light source of an input image, by comparing the color difference of a characteristic pixel of the block with the typical color difference of the block. Then, as a result of the determination, a white balance evaluating circuitdetermines the light source of an image by using blocks that reflect the light source.

Auto white balance apparatus and white balance adjusting method

The present invention provides a white balance adjustment device that is capable of adjusting white balance by estimating a color of a light source with a high degree of accuracy, even for a scene in which an object such as a leaf is present. The white balance adjustment device divides a captured image into a plurality of blocks, and extracts a representative color difference (Tg, Ti) from each block, and a characteristic pixel (Tg, Ti) having a maximum color difference in each block. The white balance adjustment device calculates a light source color estimation vector from a representative value pixel and a characteristic pixel for each block, and estimates a convergence point of light source color estimation vectors of the plurality of blocks as the color of the light source used for the input image to adjust the white balance.
