IMAGE PICKUP APPARATUS THAT COMPENSATES FOR FLASH BAND, CONTROL METHOD THEREFOR, STORAGE MEDIUM, AND VIDEO PROCESSING APPARATUS
20170366721 · 2017-12-21 ·

An image pickup apparatus which satisfactorily compensates for a flash band appearing due to an external flash and prevents a row insensitive to the flash from appearing in a corrected image. The flash band appearing in a plurality of frames consecutive in terms of time is detected based on an image signal output from an image pickup device which sequentially starts exposure and sequentially reads out signals for each row of pixels. An image in at least one of those frames is corrected to a full-screen flash image. When a width of the flash band is smaller than the number of rows in one frame, a row in which the flash band does not appear is interpolated using a row in which the flash band appears and which immediately precedes or immediately succeeds the row in which the flash band does not appear.

The effect of ambient light on a measurement taken by an imaging pixel may be reduced by employing two optical filters. The two filters may have narrow passbands that are close to each other but do not overlap. The first filter may allow ambient and active light to pass. The second filter may allow ambient light to pass but may block active light. The ambient and active light that passes through the first filter may cause electrical charge to be generated in a photodiode of the pixel. The ambient light that passes through the second filter and strikes another pixel element may control the amperage of an electrical current that depletes charge from the photodiode. For instance, the other element may be a photoresistor, the light-dependent resistance of which controls the amperage, or may be a second photodiode that generates charge that controls a transistor that controls the amperage.
