    Abstract: A region extraction device and a method thereof in a stage previous to detection of a target object, capable of appropriately extracting a region having a possibility of presence of a target object emitting light having a light emission spectrum of a specific narrowband as a determination region in an imaging region, and an object detection apparatus and a method thereof capable of efficiently detecting the target object using a region extraction result are provided.
    In a region extraction method, a plurality of images including an image of a second narrowband corresponding to a first narrowband of light emitted by a target object and an image of a third narrowband different from the second narrowband are acquired from a multispectral camera. Next, a region that emits light having a light emission spectrum other than a light emission spectrum of the first narrowband is determined as a non-determination region in an imaging region based on the plurality of acquired images, and one or a plurality of regions excluding the non-determination region from the imaging region are extracted as a determination region.

    Abstract: In an imaging device that includes an imaging lens including n number of optical systems of which imaging characteristics are different and an image sensor including m number of light receiving sensors of which combinations of crosstalk ratio and light sensitivity are different in each pixel, m number of primary image data items are generated by obtaining image signals output from the light receiving sensors of each pixel of the image sensor, and n number of secondary image data items corresponding to the optical systems are generated by performing crosstalk removal processing on the m number of generated primary image data items for each pixel. In a case where a pixel as a processing target includes the primary image data of which a pixel value is saturated, the secondary image data items are generated by removing the corresponding primary image data and performing the crosstalk removal processing.
