An imaging system includes a plurality of imaging devices facing different directions and an output unit configured to output an output image generated based on the captured images. The plurality of imaging devices is configured to capture images. The output image having been generated based on the captured images covers a range of 360 degrees in at least a first direction. In the output image, an area where a subject is reflected in the captured images is placed at a predetermined position so as to prevent the area from being cut off at the edges of the output image.

Imaging system, image processing apparatus, imaging device, and recording medium

An image processing system includes a joining processing unit configured to perform a joining process to join input images captured by an image capturing device and generate an output image the image capturing device being reflected in each of the input images; and an acceptance unit configured to receive selection of one of a plurality of modes for the joining process. The plurality of modes has a first mode to generate an output image in which at least a part of the image capturing device is reflected, through the joining process; and a second mode to, through the joining process, generate an output image whose area where the image capturing device is reflected is smaller than an area where the image capturing device is reflected in the output image in the first mode or generate an output image in which the image capturing device is not reflected.

Removal of image capture device from omnidirectional image created by stitching partial images

An imaging device includes a plurality of image sensors configured to capture a plurality of images, and processing circuitry. The processing circuitry is configured to determine whether a difference in brightness between the plurality of images exceeds a predetermined threshold. Based on a determination that the difference in brightness exceeds the predetermined threshold, the processing circuitry arranges the plurality of images side by side in one direction to be output as an output image.

Imaging device, image processing system, and image processing method

An imaging device includes an image sensor to convert an optical image of a subject into an electric signal, an image processor to generate an image according to the electric signal, an image synthesizer to synthesize, pixel-by-pixel, images generated by the image processor in a same composition under a same condition, a digital clamp processor to perform a digital clamp to remove an offset component from a synthesized image obtained by the image synthesizer, and a digital clamp controller to control a digital clamp amount of the digital clamp processor on the basis of a number of images synthesized by the image synthesizer.

Imaging device and image processing method

An image processing unit includes a memory unit in which continuously captured images including a reference image and a comparative image are stored, an image dividing unit to divide the reference image and the comparative image into image blocks of a predetermined size, a mean value calculator unit to calculate a mean value of pixel outputs in each image block of each of the reference and comparative images, a threshold determining unit to determine a threshold according to a mean value of pixel outputs of an image block of the reference image, and a determiner unit to compare the threshold with a difference value of the mean values of the pixel outputs in the image blocks of the reference and comparative images to be synthesized and determine whether the image blocks of the reference and comparative images are suitable for image synthesis based on a result of the comparison.
