Imaging apparatus with a timing generator having a rewritable storage and a method of supplying an imaging device with drive pulses from the timing generator

A method of supplying an imaging device with drive pulses comprising the steps of:

• preparing a plurality of registers storing information required for generating pulse patterns for the imaging device inside a timing generator supplying the imaging device with drive pulses;
• selecting any one of the plurality of registers;
• generating pulses of a pulse pattern for the imaging device based on the information stored in the selected register;
• rewriting the information stored in one of the registers which is not selected from outside of the timing generator;
• and
• repeating sequence of said steps to supply the imaging device with the drive pulses of various pulse patterns.

A method of supplying an imaging device with drive pulses comprising the steps of:

• storing information required for generating a pulse pattern for the imaging device in at least one register included in a timing generator supplying the imaging device with drive pulses;
• obtaining the information stored in the register;
• generating pulses of a pulse pattern for the imaging device based on the obtained information;
• rewriting the information stored in the register from outside of the timing generator during a period the register is not accessed;
• repeating a sequence of said steps to supply the imaging device with drive pulses with various pulse wave patterns;
• wherein said at least one register is provided in plural, and
• selecting any one of said registers to connect said one register selected to a first circuitry, wherein said first circuitry generating the pulses of the pulse pattern for said imaging device based on the information stored in said selected one register.

An imaging apparatus comprising a timing generator supplying an imaging device with drive pulses, said timing generator comprising:

• a plurality of registers for storing information required for generating pulse patterns for said imaging device;
• a first selector for selecting one of said plurality of registers;
• a pulse generator for generating pulses of a pulse pattern for said imaging device based on the information stored in the register selected by said first selector;
• and
• an external control circuitry for rewriting the information stored in one of said plurality of registers which is not selected by said first selector.
