Claims

[Scope of Claim for Utility Model Registration] (1) A still trigger switch that instructs still image recording during video recording, a low-brightness detection circuit that detects that the subject is of low brightness, and a low-brightness detection circuit that detects that the subject is of low brightness. When the still trigger switch is pressed, a photometry circuit starts photometry in synchronization with the signal charge readout pulse of the image sensor that is output next, and a photometry circuit that starts photometry in synchronization with the signal charge readout pulse that is output next after starting photometry. A video camera capable of recording still images, comprising: a flash circuit that emits a flash at the beginning of a vertical blanking period immediately before a pulse, and stops emitting the flash when appropriate exposure is reached. . (2) During the period from the readout pulse to the next readout pulse for reading out the signal charge exposed by the flash, the aperture, AGC circuit, and white balance circuit are fixed at predetermined values, and the readout and signal-processed signal is 2. The video camera capable of recording still images according to claim 1, wherein the signal written in the memory is recorded on the same medium as a moving image or on a separate medium after the period.
