- Imaging device imaging lens, and method of writing data to imaging lens
- the present invention relates to an interchangeable-lens type image pickup apparatus provided with an image processing apparatus for superimposing an image of a subject picked up by an image sensor and a scale representing a reference length on a screen of a display, and an interchangeable lens used for the same. .
- a scale is projected on the screen so that the size of the subject can be easily grasped. If the optical magnification is constant, it is sufficient to display a scale of a certain size. If a lens with a variable optical magnification such as a zoom lens is used, the size of the scale is also changed according to the magnification. There is a need.
- Such a conventional imaging apparatus detects the positions of a movable lens for magnification adjustment and a movable lens for focus used in a zoom lens, and calculates the optical magnification of the lens based on the detected positions.
- the scale size is now set.
- Patent Document 1 JP-A-10-210327
- an imaging device having a high magnification such as a microscope, is used to adjust the focus by relatively moving the stage in the optical axis direction. Since the lens has a short length and the magnification is high, the depth of field is extremely shallow, and the subject distance is uniquely determined.
- an imaging apparatus has been proposed in which positional information of a lens is read based on an output signal of a drive unit of a movable lens for magnification adjustment, a magnification is calculated, and a scale is set.
- Patent document 2 JP-A-2000-155268
- a single-focal lens is about 5% of a lens, and a zoom lens is about 10%. Since there is a rate error, if an attempt is made to simply detect the magnification based on the output signal of the driving section of the movable lens, it naturally includes an error of about 5 to 10%.
- the position information of the magnification adjusting movable lens is output from the zoom lens, and the magnification is detected based on the position information by the imaging device main body. It is necessary to store lens-specific data necessary for converting information into magnification.
- the imaging apparatus when used as a microscope, it is required that observation can be performed at an appropriate magnification over a wide range up to several hundreds of times, for example, depending on the observation object (subject), and only one zoom lens is required. In this case, the adjustable range of the magnification is limited, and the magnification cannot be set freely.
- the use of an imaging device capable of exchanging lenses can meet the demand, but if the lenses are exchanged, lens-specific data for calculating the magnification based on the position information of the lenses will be lost. Since each is different, the enlargement magnification cannot be calculated. Further, since a fixed magnification lens does not have a variable lens for magnification adjustment, it is not possible to calculate an enlargement magnification based on the position information.
- the present invention is to make it possible to display a scale representing a reference length on a screen of a display with an accurate length, regardless of which lens is replaced when the imaging device is of an interchangeable lens type. As a technical issue.

- An optical magnification output unit that outputs a preset optical magnification, wherein the image processing apparatus calculates an actual magnification on a display screen based on the optical magnification, the image sensor size, and the screen size;
- a scale setting means for setting a scale based on the calculated actual magnification and the reference length of the scale to be displayed.
- the magnifying imaging interchangeable lens according to the present invention is a magnifying imaging interchangeable lens that is detachably attached to the main body of the imaging device provided with the image sensor, and outputs an optical magnification measured in advance.
- Optical magnification output means are provided.
- the interchangeable lens mounted on the imaging apparatus main body includes an optical magnification output unit, and is set in advance for each lens. Since the adjusted optical magnifications are individually output, accurate optical magnifications can be obtained even if the lens is replaced.
- the actual magnification on the display screen is calculated based on the image sensor dimensions and the screen dimensions by, for example, the following equation.
- MO Optical magnification of lens
- the length L of the scale on the image is obtained by the following equation, and the scale of the correct length can be displayed on the display screen.
- the interchangeable lens is a zoom lens provided with a movable lens for magnification adjustment
- the position of the movable lens or the position of the movable part corresponding to the movable lens position is detected as in claims 3 and 6.
- a storage element that stores position-to-magnification conversion data that outputs the optical magnification according to the position detected by the position sensor based on the optical magnification measured in advance. An accurate optical magnification is output according to the position detected by the position sensor, and the length of the scale can be accurately changed and displayed in real time based on the output.
- the problem that the scale representing the reference length can be displayed on the display screen with an accurate length even when the lens is exchanged is to output the optical magnification from the interchangeable lens. Achieved from here.
