固体撮像装置およびその駆動方法
Document Type and Number:
Japanese Patent JP4552006
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain information on focusing and photometry at a short time normally by making a first horizontal transfer element output all signal charges in a photosensitive area and making the second horizontal transfer element output a signal charge in an extract area. SOLUTION: Normally, all signal charges in i×j numbers of photosensitive cells 130 in a photosensitive area PA are supplied to a vertical transfer CCD 131, a signal charge that is held in accordance with a drive signal from a drive signal generation part 12 is transferred to a first horizontal transfer CCD 132 and the signal charges from all the pixels are read out. At the time of focusing and photometry, a jumping gate 134 is turned on, a signal charge held by the vertical transfer CCD which transfers a signal charge of an extract area SA is transferred to a second horizontal transfer CCD 133, which is short and a signal charge held by the vertical transfer CCD that transfers the signal charges in areas except for the SA area are transferred to a discharge drain 135. If the length of the second transfer CCD is made half that of the first horizontal transfer CCD can be read out in half the time.
