Abstract: PROBLEM TO BE SOLVED: To provide a method in which a false image working on a single image is removed from the image and a flicker need not be monitored independently without requiring any additional inputs excepting the flicker and the value of a frame period. SOLUTION: In the method in which the false image is removed from the image of a scene displayed by an image data and brightened by a light source, the method contains a step (30) where a flicker function is allocated, and a step (40) where the image data are processed by using the flicker function and the false image is removed from the image. According to one mode, the image data are composed of an image data array consisting of a plurality of rows of image data, and a processing step contains a step where the image data are divided by the flicker function in a row-unit base. According to one mode, the flicker function is the function of the flicker frequency, flicker amplitude and flicker phase of the light source.

Abstract: PROBLEM TO BE SOLVED: To provide a method for improving the image quality of a digital image forming device such as a digital camera over a wide signal level range. SOLUTION: The method includes steps of; providing a digital image signal; and selecting a color corrector based at least in part on an S/N of the digital image signal to correct the digital image signal. In an embodiment of this invention, the digital image signal includes an output from an image sensing device (14), and an S/N estimate device (18) calculates an estimated value of the average S/N of the output digital image signal. The color corrector possibly being a color correction matrix (22) is selected on the basis of the estimated average S/N.

Abstract: PROBLEM TO BE SOLVED: To provide an image processing system and method for subtracting dark noise from images without requiring use of "black pixel". SOLUTION: An image processing system 10 subtracts dark noise out of images based on a dark noise scale factor 220. The image processing system 10 includes an image sensor 20 for capturing a current image and producing current image data 50 representing the current image. The current image data 50 include both a dark noise signal and an image signal 90. The dark noise scale factor 220 for the current image is estimated from the current image data 50 and reference image data 80 representing a reference dark noise signal. The reference dark noise signal is scaled by the dark noise scale factor 220 to produce a scaled dark noise signal, and this signal is subtracted from the current image data 50 to produce the image signal 90.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for conducting detailed analysis for sensor-detected images in other apparatuses.
SOLUTION: In the method and the apparatus, which are used for advanced dispersion analysis for images, an image is inputted and analyzed, and then feature information is extracted from the inputted image. The extracted feature information is used to determine whether features satisfy specified conditions. If they satisfy the conditions, feature information is transmitted for further analysis. The extracted feature information is stored and used for generation of statistical information related to the extracted feature information. In addition, for performing further analysis included with event detection or recognition, further feature information is provided from other databases. Thereby, advanced variance analysis for analyzing inputted images becomes available, and event detection or recognition can be performed efficiently.
