In motion invariant photography, blur is introduced by a structured movement of the camera during capture. The structured movement results in a uniform blur which simplifies deblur through post-processing for objects moving at different speeds in a single motion plane. However motion invariance depends on the camera speed exceeding the object speed (in the image plane) by a significant amount. ...

In this paper, we analyze the visual discomfort caused by camera panning in 4K UHD contents. UHD is expected to provide a sense of realness to viewers, with four times more pixels than HD. However, UHD may yield undesirable artifacts, such as the stroboscopic effect from displaying frequency and visual fatigue due to moving objects. To investigate the visual discomfort in the presence of camera...

This paper present an automated reconstruction high level architectural specification of image merging for satellite image capturing system, aiming at implementing a real-time satellite image processing system for merging more than one fixed size sequential images capture by a fix speed and unidirectional moving satellite camera to generate a large fixed size image. Also focuses on the key arch...

For the camera calibration, point correspondence data between 3D and 2D points widely spreading over the image plane is necessary to get a precise result. However, in the case of wide observing area, it is impractical to use a huge calibration object that covers the camera view. This paper presents a refined calibration method using circular patterns. We already proposed a circular pattern base...

This paper introduces a short-wave infrared camera logic design based on FPGA. The hardware adopts the architecture of Sofradir Tecless SWIR detector SW640+Xilinx FPGA xc4vsx55, which has dual working mode 640×512 at 25 FPS and 64×48 4000 FPS. function high precision target tracking can be realized by frequency capture laser signal. In this design, non-uniform correction coefficient table in SD...

The Brandaris 128 ultra-high-speed imaging facility has been updated over the last 10 years through modifications made to the camera's hardware and software. At its introduction the camera was able to record 6 sequences of 128 images (500 × 292 pixels) at a maximum frame rate of 25 Mfps. The segmented mode of the camera was revised to allow for subdivision of the 128 image sensors into arbitrar...

This paper proposes a spectral imaging technology by synchronizing a programmable light source and a high-speed monochrome camera. The light source is capable of emitting arbitrary spectrum in high speed, so that the system has the advantage of capturing spectral images without using filters. The camera and the light source are controlled by a computer in order to capture image sequence synchro...
