Abstract
A photographing apparatus and method employ an imaging device arranged including a matrix of pixels each which accumulates accumulation charges according to an amount of light incident thereon, an accumulation charge read device for reading the accumulation charges at a time difference based on the position of each row or column of the pixels, and a reset device resetting an entirety of the accumulation charges of the imaging device before a main exposure. The photographing apparatus and method each further employ a reset timing change device capable of changing a reset timing for resetting the accumulation charges with respect to a synchronization pulse corresponding to a time for reading the accumulation charges.
Claims22
A photographing apparatus comprising:
- an imaging device arranged including a matrix of pixels, each which accumulates accumulation charges according to an amount of light incident thereon;
- an accumulation charge reader that reads the accumulation charges at a time difference based on the position of each row or column of the pixels;
- a reset device that resets an entirety of the accumulation charges of the imaging device before a main exposure;
- and
- a reset timing changer that changes a reset timing for resetting the accumulation charges with respect to a synchronization pulse corresponding to a time for reading the accumulation charges.
A photographing method comprising:
- operating an imaging device, arranged including a matrix of pixels, so that each said pixel accumulates accumulation charges according to an amount of light incident thereon;
- reading the accumulation charges at a time difference based on the position of each row or column of the pixels;
- resetting an entirety of the accumulation charges of the imaging device before a main exposure;
- and
- changing a reset timing for resetting the accumulation charges with respect to a synchronization pulse corresponding to a time for reading the accumulation charges.
