TL;DR: In this paper, an image processing apparatus capable of obtaining a novel image is described, where an image input unit acquires a plurality of frames constituting a moving image, and stores them into an image buffer (14).
Abstract: An image processing apparatus (10) capable of obtaining a novel image. An image input unit (12) acquires a plurality of frames constituting a moving image, and stores them into an image buffer (14). A processing execution unit (16) reads frames to be reproduced from the image buffer (14) as reproduction targets. An image conversion unit (18) applies image processing to the frames to be reproduced. An image output unit (20) outputs the frames to a monitor (24). A buffer adjusting unit (22) stores the reproduced frames into the image buffer (14) as past frames, and drops some of the frames at predetermined time intervals.

TL;DR: In this paper, the problem of selecting a conversion factor for a static/animation image conversion encoding system by selecting the prescribed number of conversion factors for the bit value generated by the conversion factors in view of the variation value of restored picture quality is addressed.
Abstract: PROBLEM TO BE SOLVED: To select a conversion factor for a static/animation image conversion encoding system by selecting the prescribed number of conversion factors for the bit value generated by the conversion factors in view of the variation value of restored picture quality. SOLUTION: A bit value calculation part 52 calculates the bit value of a factor that undergone the discrete cosine transformation. A local decoder 54 restores the factor that undergone the discrete cosine transformation and generates a restored block. Then a control part 56 selects the prescribed number of conversion factors in view of the variation of bit value that is caused when every conversion factor is selected together with the block variation value due to the error caused between an input block and a block which is restored by the decoder 54 in regard to every conversion factor after reception of the input block.

TL;DR: In this paper, the coordinate conversion information is used in next reception to insert longitudes, latitudes, shore lines, etc., into the received image by a quick look, and further image display data from an image data memory 4 and map display from the map data memory 7 are positioned and outputted to the display part.
Abstract: PURPOSE:To display information instantaneously and understand the display image plane instantaneously by providing an image processing part which outputs the display image to a display part while performing gridding and mapping the display image. CONSTITUTION:Coordinate conversion information which is sent together with image data is stored in a coordinate conversion information memory 5. The coordinate conversion information is used in next reception. The image data (output of reception part 2) which is received currently is gridded and mapped with parameters which are generated between last reception and current reception from information stored in the image conversion information memory 5 in the last reception and stored in a G/M table 6 and stored in a map data memory 7 as map data, and further image display data from an image data memory 4 and map display data from the map data memory 7 are positioned and outputted to the display part 7. The display part 7 displays both display data one over the other to insert longitudes, latitudes, shore lines, etc., into the received image by a quick look.

TL;DR: In this paper, a method for measuring photosynthetically active radiation (PAR), and particularly fraction-absorbed PAR (faPAR) measurements, which shows a relationship between how much energy is available compared with how much power is actually used, or absorbed, by plants in a region of interest, can include calibrating multiband image data to generate reflectance-calibrated values for each band of the multi-spectral image data.
Abstract: A method for measuring photosynthetically active radiation (PAR), and particularly fraction-absorbed PAR (faPAR) measurements, which shows a relationship between how much energy is available compared with how much energy is actually used, or absorbed, by plants in a region of interest, can include calibrating multiband image data to generate reflectance-calibrated values for each band of the multiband image data. The weighted reflectance data of the bands can be combined, along with down-welling light data captured at the time of the multi-spectral images to generate a faPAR image. In some cases, faPAR is generated using a ratio of up-welling PAR (uPAR) to down-welling PAR (dPAR). The dPAR can be generated using partially-reflectance-calibrated data and fully-reflectance-calibrated data and the uPAR can be generated using the partially-reflectance-calibrated data.
