Imaging apparatus, imaging control method and recording medium readable by computer

Abstract

TG (22) (timing signal generator), frequency divider (28), oscillator (27), and signal processing IC (30) generate the drive signal and transfer signal of CCD (21), and when CCD (21) passes Wherein for exposure for a long time exposure not less than a predetermined time period, adjusting each of the clock frequency of the drive signal during the exposure period and the clock frequency of each of the drive signal and the transfer signal during the transfer period is is lower than a corresponding clock frequency in an exposure state in which exposure is performed for less than said predetermined period of time.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2005-180519 filed on June 21, 2005, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an imaging device, an imaging control method, and a computer-readable recording medium. In particular, the present invention relates to modification of exposure control or transfer control for so-called CCD, CMOS, etc. imaging devices. Background technique [0004] Imaging devices such as so-called digital still cameras and digital video cameras each include an imaging device such as a CCD or CMOS, which can obtain a projected image as a signal in near real time. [0005] In cases where cameras with such imaging devices are used to photograph stars etc. at night, long exposures must be made, for example more than 3 minutes. [0006] However, a signal driving a CCD or the like or a peripheral circu...

Problems solved by technology

[0016] However, with recent digital cameras, as the number of image pickup devices increases (higher pixel count), the amount of data that should be read out increases, and at the same time, an increase in operation speed is required.
