发明名称 Imaging apparatus capable of controlling exposure including flash amount control of flash apparatus, and control method thereof
摘要 There is provided an imaging apparatus capable of reducing effects given by an object outside a dynamic range of the camera, and capturing an object image with appropriate exposure, when a camera performs imaging. The imaging apparatus is configured to separate image data into a plurality of blocks, extract a specific-color block using an average value of each color component acquired using only a pixel group whose pixel output is included within a predetermined range and the number of the groups, set a weighting coefficient of an exposure-amount calculation for the block to be determined as the specific color, and set the exposure based on the weighting coefficient and an average value of brightness acquired using only the pixel groups whose pixel output and the average value of the brightness of the block are included within the predetermined range.

主权项 1. An imaging apparatus comprising: an imaging unit; a generation unit configured to generate image data including a plurality of color components from output of the imaging unit; a brightness calculating unit configured to calculate, for a plurality of light measuring blocks into which the image data is separated, an average value of brightness value of small blocks including a plurality of color components whose pixel output is included within a predetermined range, wherein each light measurement block includes a plurality of small blocks; a specification unit configured to specify a specific light measurement block including a predetermined number or more of the small blocks; and an exposure-amount calculation unit configured to calculate an amount of exposure when the imaging unit captures an image using the average value as a brightness value of the specific light measurement block.
