Abstract
An image sensing apparatus has a plurality of pixels arranged in a matrix-like layout and containing photoelectric conversion devices reads signals in units of one line or a plurality of lines and is provide with an image sensing device 14 adapted to read a signal from a given block area. The apparatus has a flash read mode that, during flash operation, adjusts parameters relating to the readout of the image sensing device 14 so as to produce the same exposure period for all the plurality of lines that comprise a predetermined block area of the image sensing device 14, thus enabling accurate quantity of light detection even when performing strobe photography at high shutter speeds.
Claims18
An image sensing apparatus comprising:
- an image sensing unit in which pixels containing photoelectric conversion devices are arranged in a plurality of lines;
- a drive unit configured to drive the image sensing unit so as to shift an exposure period in units of one line or a plurality of lines;
- and
- a control unit configured to be capable of switching a read mode which reads a signal from a predetermined area of the image sensing unit during flash to a flash read mode different from that during through-display that displays continuous images output sequentially from the image sensing unit on a display unit,
- wherein the flash read mode configured so that a portion of an exposure period of the first line read and the exposure period of a portion of the last line read overlap in time.
An image sensing apparatus comprising:
- an image sensing unit in which pixels containing photoelectric conversion devices are arranged in a plurality of lines;
- a drive unit configured to drive the image sensing unit so as to shift an exposure period in units of one line or a plurality of lines;
- and
- a control unit configured so as to be capable of switching a read mode which reads a signal from a predetermined area of the image sensing unit during flash to a flash read mode different from that during through-display that displays continuous images output sequentially from the image sensing unit on a display unit,
- wherein the flash read mode configured so that a read period of a signal output from a predetermined area of the image sensing unit is shorter than that of the through-display read mode.
A control method for an image sensing apparatus having an image sensing unit in which pixels containing photoelectric conversion devices are arranged in a plurality of lines and a drive unit configured to drive the image sensing unit so as to shift an exposure period in units of one line or a plurality of lines,
- the control method comprising the step of switching a read mode which reads a signal from a predetermined area of the image sensing unit during flash to a flash read mode different from that during through-display that displays continuous images output sequentially from the image sensing unit on a display unit,
- wherein the flash read mode configured so that a portion of an exposure period of the first line read and the exposure period of a portion of the last line read overlap in time.
A control method for an image sensing apparatus having an image sensing unit in which pixels containing photoelectric conversion devices are arranged in a plurality of lines and a drive unit configured to drive the image sensing unit so as to shift an exposure period in units of one line or a plurality of lines,
- the control method comprising the step of switching a read mode which reads a signal from a predetermined area of the image sensing unit during flash to a flash read mode different from that during through-display that displays continuous images output sequentially from the image sensing unit on a display unit,
- wherein the flash read mode configured so that a read period of a signal output from a predetermined area of the image sensing unit is shorter than that of the through-display read mode.
