摘要： Signal levels of input three, R, G, and B, color video signals are examined by a level examining circuit. After a knee-compression is performed to the video signals, a selector selects the maximum knee-compressed color signal and the minimum knee-compressed color signal. A compression coefficient calculator calculates a compression coefficient of each color signal before and after the knee-compression. A medium color signal calculator determines a medium color signal. Another selector turns the compressed video signals back to three, R, B, and G, color signal outputs and releases them. Because the difference between any two of the R, G, and B color signals is equally compressed before and after the high-brightness compression, any change in a hue can successfully be avoided.

摘要： In a noise reducer, a first subtractor 101 generates a difference N1 between an input video signal Ynow and a delayed video signal Ypre output from a frame memory 104 and obtained by delaying an output video signal Yout by a time corresponding to one screen. An amplitude adjuster 102 adjusts the amplitude of an output signal of the first subtractor 101 based on a motion signal MV. A second subtractor 103 subtracts an output N2 of the amplitude adjuster 102 from the input video signal Ynow. A motion detector 2 calculates the amount of change in the input video signal Ynow with respect to the delayed video signal Ypre for each of pixels constituting one screen, and generates, as the motion signal MV, a signal determining, as “moving,” a predetermined proportion of pixels for which the amount of change is smaller than a predetermined threshold value.

摘要： When capturing images of a subject with an imaging device that uses a CMOS image sensor, a white band-shaped artifact appears in the imaging signal due to the influence of a rolling shutter operation performed when an external flash has been emitted. Manipulating or removing images in which such an artifact appears requires specifying the frames in which the artifact appears. A line averaging unit (11) calculates the average luminance level of each line in the imaging signal, the average luminance levels are temporarily stored by a storage unit (12), and thereafter a frame difference calculation unit (13) calculates the difference between the line average luminance levels and the line average luminance levels of the next frame. These frame difference values are compared with a reference value, and it is determined that the influence of an external flash is present if a portion of interest with high values is continuous for one frame period.
