  • Patent number: 10129475
    Abstract: An image capturing apparatus includes an image sensor and a processor. The image sensor includes an imaging plane that receives an image of a shooting target field through color filters according to two or more wavelength regions and outputs a signal of the image of the shooting target field. The processor is configured to set a larger weight for a wavelength region having a higher image forming performance than for a wavelength region having a lower image forming performance in accordance with a high-resolution direction determined in the image of the shooting target field, generate image data based on the signal output by the image sensor, and detect an object in the generated image data.
    Type: Grant

  • Patent number: 9955128
    Abstract: The present invention provides an imaging apparatus which can reduce the lowering of the precision of the object detection, when detecting the object by using photometric optical elements and a photometric image sensor. The imaging apparatus detects the object by using the photometric optical elements and a photometric, sensor. In this case, weighting coefficients Wr, Wg and Wb are each set at a region in which H in the photometric region is divided into three from the image height 0. The imaging apparatus is structured so as to form information for the object detection by using weighting coefficients which have been set for each of the wavelength regions according to the regions in the photometric region, and accordingly can reduce the lowering of the precision of the object detection.

  • Patent number: 8670658
    Abstract: A subject is tracked during continuous shooting, and the degree of reliability of the tracking result is determined. When it is determined that the degree of reliability of the tracking result is high, control values of exposure used to capture an image of the previous frame are configured as those used to capture an image of the next frame, thereby omitting calculation of control values of exposure. Upon this operation, in an image capture apparatus having a continuous shooting function, and a method of controlling the same, suppression of exposure variations and shortening of the exposure calculation time during continuous shooting can be effectively achieved.
