Image-taking apparatus, image-taking system and control method of image-taking apparatus

摘要

An image-taking apparatus is provided with an image-pickup device, a control circuit and a detection circuit. The image-pickup device includes a plurality of pixels and the control circuit controls the driving of the image-pickup device. The detection circuit detects the movement of an object in an image-taking area based on an image signal generated using the image-pickup device. The control circuit controls the driving of the image-pickup device so as to take an image with a first number of pixels when the detection circuit does not detect any movement of the object and take an image with a second number of pixels which is larger than the first number of pixels when some movement of the object is detected.
