To enable to display a scale indicative of a reference length on a screen of a display at an accurate length even when exchanging the lens in an image pickup apparatus to any lens. In a case of mounting an exchange lens (F,Z) to an image pickup apparatus main body () and displaying an image of an object picked up by an image sensor () and a scale () indicative of a reference length in juxtaposition on a screen of a display (), a previously measured optical magnification or an actual magnification is outputted from optical magnification outputting means () provided to the exchange lens (F,Z) is outputted, an actual magnification on the screen of the display () is calculated based on the optical magnification, the size for the image sensor and the screen size, and the size of the scale on the screen is set based on the actual magnification and the reference length of the scale by a scale setting means ().

Image pickup apparatus, image pickup lens, and data writing method to image pickup lens

A lighting apparatus in which plural light emitting devices for illuminating light to an object to be illuminated from the periphery thereof are put to light control, and a control device is provided for controlling light to the light emitting devices on every segment divided isogonally with respect to the lighting center at which the light is focused by a control device, wherein the control devicecomprises an illuminance distribution setterthat sets the illuminance on every segments Sto Sindividually in accordance with the start position of a vector that represents the lighting direction to the lighting center F on the XY coordinate plane D with the lighting center F being as an origin P, and a light controllerthat reads out the illuminance on every segment from the illuminance distribution setterin accordance with the input data from a two dimensional data input devicethat sets the start position and controls the light.

Lighting apparatus and image pick-up apparatus with lighting

A current to light emitting devices when an application voltage is at or higher than the lower limit voltage for lighting determined by the arrangement of the light emitting devices, and an identification circuit that outputs a current identification signal in accordance with an appropriate current for the lighting circuit when the application voltage is lower than the lower limit value for lighting, and the power supply comprises a driving power supply that applies a lighting voltage at or higher than the lower limit voltage for lighting, an identification power supply that applies an identification voltage at or lower than the lower limit voltage for lighting, a current setter that sets an appropriate current to be supplied to the lighting circuit based on the current identification signal outputted from the identification circuit.

Lighting method, lighting apparatus and components used therefor

An illumination apparatus for illumination of light by emitting light from LED for each of RGB colors capable of optionally setting a color temperature and controlling the brightness after the setting while maintaining the color temperature as it is, in which a light control circuit supplies a light control voltage for variably controlling the light quantity of the illumination light equally to each color setting circuit connected with LED of each color which is lit by a light quantity in proportion with a driving current and a color temperature setter of the color temperature setting circuit adjusts the light control voltage by a predetermined ratio to a control voltage, and a constant current circuit outputs a driving current in accordance with the control voltage to each LED for each of RGB colors.
