Light source apparatus for endoscope

A light source apparatus for an endoscope, which has a light source for supplying exposure light for illuminating an object to the endoscope that is equipped with a photographing device when the object is photographed, comprising:

• an exposure controller than controls a quantity of exposure light applied to a photographic plane in said photographing device;
• a condition inputter that inputs various plural categories of conditions previous to the object being photographed for setting an exposure index which is used to determine said exposure light quantity, said categories of conditions being different from each other, said condition inputter having a memory for storing various conditions and a condition selector that selects appropriate conditions from among the various conditions stored in the memory, said condition inputter having a combination storer that stores a combination of conditions selected through said condition selector, and a combination selector that selects a combination of conditions in said combination storer;
• and
• an exposure index setter that calculates said exposure index from various of said plural categories of conditions which are inputted through said condition input means and outputs said exposure index to said exposure controller.

A light source apparatus for an endoscope, which has a light source for supplying exposure light for illuminating an object to the endoscope that is equipped with a photographing device when the object is photographed, comprising:

• exposure control means for controlling the quantity of exposure light applied to a photographic plane in said photographing device;
• condition input means for inputting various plural categories of conditions previous to the object being photographed for setting an exposure index which is used to determine said exposure light quantity, said categories of conditions being different from each other;
• and
• exposure index setting means for calculating said exposure index from various of said plural categories of conditions which are inputted through said condition input means and outputting said exposure index to said exposure control means, wherein said various plural categories of conditions that are inputted through said condition input means include the kinds of endoscope, camera and film.

A light source apparatus for an endoscope, which has a light source for supplying light for illuminating an object to the endoscope that is equipped with a photographing device, comprising:

• a data storer that stores data which is required to determine a quantity of exposure light applied to a photographic plane in said photographing device, said data storer being interchangeably provided and storing exposure indexes corresponding to at least two devices which are employed in a photographing operation, said data being used to select at least one device employed in said photographing operation;
• a reader that reads said data from said data storer;
• and
• an exposure controller that controls said exposure light quantity using said data which is read by said reader.

A light source apparatus for an endoscope, which has a light source for supplying light for illuminating an object to the endoscope that is equipped with a photographing device, comprising:

• a read only memory that stores data which is required to determine a quantity of exposure light applied to a photographic plane in said photographing device, said read only memory being interchangeably provided;
• a reader than reads said data from said read only memory;
• and
• an exposure controller that controls said exposure light quantity using said data which is read by said reader.
