Abstract:
A capture apparatus of video image is provided with image sensors and an image composer. Each image sensor continually captures plurality sets of video image data, wherein each set of video image data includes odd frame image data and even frame image data and the images sensors includes a first set of image sensors and a second set of image sensors. The image composer is coupled to the image sensors and is configured to filter the odd frame image data from the video image data of the first set of image sensors and the even frame image data from the video image data of the second set of image sensors, compose the odd frame image data and/or the even frame image data to generate an output image with a fixed output resolution according to an input resolution of the video image data and the fixed output resolution.
Abstract:
An exposure-control system and an associated exposure control method are provided. The exposure-control system includes: an image capturing unit configured to capture a long-exposure image and a short-exposure image with a first exposure value and a second exposure value, respectively; and a processor, configured to calculate histograms of the long-exposure image and the short-exposure image, and calculate an exposure ratio according to the calculated histograms, the first and second exposure values, wherein when the exposure ratio is smaller than a first threshold, the processor switches a current exposure mode to a low dynamic range mode. When the exposure ratio is larger than a second threshold, the processor switches the current exposure mode to a high dynamic range mode. When the exposure ratio is between the first threshold and the second threshold, the processor does not switch the current exposure mode.
