Abstract
There is provided an electronic camera comprising an imaging element which photo-electrically converts an object field light, a timing generator including an internal register in which timing of a drive signal used to operate the imaging element can be programmed, a power supply control portion which supplies a second voltage to the imaging element when a predetermined time has elapsed after supply of a first voltage to the timing generator, and a control portion which starts at least program setting in the internal register of the timing generator after elapse of a time that the timing generator requires to operate stably at the first voltage and before elapse of a time that the imaging element requires to operate stably at the second voltage.

An electronic camera comprising:
- an imaging element which photo-electrically converts an object field light;
- a timing generator including an internal register in which timing of a drive signal used to operate the imaging element can be programmed;
- a power supply control portion which supplies a second voltage to the imaging element when a predetermined time has elapsed after supply of a first voltage to the timing generator;
- and
- a control portion which starts at least program setting in the internal register of the timing generator after elapse of a time that the timing generator requires to operate stably at the first voltage and before elapse of a time that the imaging element requires to operate stably at the second voltage.
An electronic camera comprising:
- an imaging element which photo-electrically converts an object field light;
- a timing generator including an internal register in which timing of a drive signal used to operate the imaging element can be programmed;
- a power supply control portion which supplies a second voltage to the imaging element when a predetermined time has elapsed after supply of a first voltage to the timing generator;
- and
- a control portion which performs program setting in the internal register of the timing generator, reads and verifies a set value after elapse of a time that the timing generator requires to operate stably at the first voltage and before elapse of a time that the imaging element requires to operate stably at the second voltage.
An electronic camera comprising:
- an imaging element whose handling electric charge quantity can be changed;
- a voltage control portion which controls a substrate voltage used to change the handling electric charge quantity of the imaging element;
- a read portion which controls an operation to take out electric charges stored in each pixel of the imaging element and read them as an image signal to the outside;
- an amplification portion which amplifies the image signal read by the read portion;
- and
- a voltage control inhibition portion which inhibits a control over the substrate voltage by the voltage control portion when an amplification factor of the amplification portion is not less than a predetermined value.
An electronic camera comprising:
- an n:1 (n is a natural number not less than 3) interlace read type imaging element which can read electric charges of a plurality of two-dimensionally arranged photodiodes to the outside through a transfer path;
- an unnecessary electric charge flushing portion used to transfer unnecessary electric charges stored in the transfer path at a normal speed through the transfer path;
- a signal read portion which reads the electric charges of the photodiodes to the outside of the imaging element after flushing the unnecessary electric charges;
- and
- a conversion portion which converts a signal read by the signal read portion into a video signal,
- wherein the unnecessary electric charge flushing portion transfers the unnecessary electric charges stored in the transfer path at a normal speed through the transfer path in a period after end of exposure of the imaging element before reading the electric charges of the photodiode to the transfer path.
