ActiveUS20120026359A1Reliably determinedIncrease in circuit scaleTelevision system detailsImage analysisFrame differenceCMOS
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.

In the case where a subject is captured by an imaging apparatus that employs a CMOS image sensor, white band interference appears in the captured signal due to the influence of rolling shutter operations when an external flash such as a camera flash has occurred; the present technique obtains an image in which that interference has been corrected even during electronic shutter imaging.An image capturing unit outputs both a valid video signal (a primary video signal) and an unnecessary video signal (a secondary video signal) as an output signal; a flash detection unit detects white band interference caused by an external flash; and a flash correction unit delays the valid video signal using a first delay unit and delays the unnecessary video signal using a second delay unit. When white band interference has occurred, the outputs of the respective delay units are added together by an adding unit, generating a corrected signal. An output selection unit selects and outputs the signal from the first delay unit in normal times, and when interference caused by an external flash has occurred, selects and outputs the corrected signal.
