Abstract
An electronic camera is provided with an image pickup sensor, a flash repeating an emission of a flashlight plural times according to a light emission timing pulse which repeats plural times, a photographic lens leading photographic light to an image pickup sensor in which the photographic light is composed of external light and a reflected light of a flashlight emitted by the flash, and an MPU generating a light emission timing pulse according to a timing based on a generation timing of an action timing pulse and controlling a timing for emitting a flash light emitted by the flash.
Claims9
An electronic camera comprising:
- an image pickup sensor having n photo detector element lines where n>2, each of the photo detector element lines comprising a plurality of arranged photo detector elements so as to form a matrix of the photo detector elements, a different action timing pulse being associated with each of the n photo detector element lines during exposure of an entire picture, each of the different action timing pulses being triggered at a different time, all of the photo detector elements within a given said photo detector element line converting incident light into respective photoelectric charges only when triggered by the action timing pulse associated with the given photo detector element line during a predetermined shutter time;
- a flash repeating an emission of a flashlight a plurality of times during the exposure of the entire picture according to a light emission timing pulse repeating a plurality of times;
- a photographic lens leading photographic light to the image pickup sensor in which the photographic light is composed of external light and a reflected light of the flashlight emitted from the flash;
- and
- a light emission controller generating the light emission timing pulse at a timing based on a generation timing of the action timing pulse, and controlling a light emission timing of the flashlight emitted by the flash.
An electronic camera comprising:
- an image pickup sensor comprising a plurality of photo detector elements arranged into a plurality of lines to form a matrix, each line being only one said element wide;
- a timing generator producing an output that sequentially selects each one of the lines so that each said photo detector element within a currently selected said line generates an output based on light falling upon said photo detector element;
- a flash strobe device;
- a photographic lens arranged to pass photographic light to the image pickup sensor, the photographic light including external light and reflected light emitted by the flash strobe device;
- and
- a flash controller connected so as to cause the flash device to produce a separate strobe of flash light as each said line is selected by the timing generator.
