ASR stands forAdaptive Sensor Resolution. It is HoverCam''s proprietary patent-pending technology for dynamically scaling and cropping. This technology allows the camera to deliver 8MP images dynamically adapted to the resolution of the user''s monitor or output display. Some other manufacturers state their document cameras use a 5MP sensor, yet they only seem to output 720P or 1080i video, which is only 1 megapixel per frame. With the Solo 8, the end-user receives a true 8MP image.
Digital cameras are designed to use a sensor''s full resolution for capturing still images, but during video recording the video is scaled or cropped to a lower resolution. For example, high-end SLR cameras report resolutions as high as 20MP or 40MP. However, you can only get the 20MP or 40MP resolution in a still image, not in video. When recording video, you only get 720P or 1080P resolution, which is equivalent to 1MP and 2MP respectively. Other manufacturers'' document cameras may have a 5MP sensor, but in reality the video is scaled down to show 720P which is 1MP resolution.The reasons for delivering low resolution video were based on the consideration that display screen sizes are normally much smaller than the maximum sensor resolution, or, the storage devices have limited capacity, or, bandwidth limitation. For document camera consumers, however, the higher sensor reading is meant as window dressing to enhance product specifications, with little or no gain in performance.
HoverCam Ultra 8 achieves delivery of true, full 8MP resolution at full-motion speed with no permanent compromise in clarity/resolution. Every frame is captured with 8 million pixels, followed by a frame by frame scaling and cropping process to fit the viewing area of interest to the maximum size of the display area. The Solo 8''s 8MP sensor is fully utilized to deliver full resolution for video viewing or recording at any given time.
