## Abstract

An endoscope apparatus according to an aspect of the invention comprises an imaging unit, a detection unit, a process unit, and a measurement unit. The imaging unit comprises an imaging device and generates a first image having two fields by imaging a subject by performing interlaced driving for the imaging device. The detection unit detects the amount of shake of the first image. The process unit generates a second image from the first image based on the amount of shake. The measurement unit measures the subject based on the second image.

## Claims

### Claim 1

An endoscope apparatus comprising:
an imaging unit which comprises an imaging device and generates a first image having two fields by imaging a subject by performing interlaced driving for the imaging device;
a detection unit which detects an amount of shake of the first image;
a process unit which generates a second image from the first image based on the amount of shake;
a measurement unit which measures the subject based on the second image;
a display unit which displays the second image generated by the process unit after displaying the first image; and
an operation direction unit which is operable by a user to input an operation direction,
wherein when the first image is displayed by the display unit and a first operation direction is input to the operation direction unit, the display unit continues to display the first image and displays an index which represents the amount of shake of the first image which is detected by the detection unit.

### Claim 2 (depends on 1)

The endoscope apparatus according to claim 1, wherein when the display unit continues to display the first image in accordance with the first operation direction and a second operation direction is input to the operation direction unit, the process unit generates the second image based on the amount of shake, and the display unit displays the second image instead of the first image.

### Claim 3

An endoscope apparatus comprising:
an imaging unit which comprises an imaging device and generates a first image having two fields by imaging a subject by performing interlaced driving for the imaging device;
a detection unit which detects an amount of shake of the first image;
a process unit which generates a second image from the first image based on the amount of shake;
a measurement unit which measures the subject based on the second image; and
a control unit which prohibits measurement to be performed by the measurement unit in a case where the amount of shake exceeds a predetermined amount.

### Claim 4 (depends on 3)

The endoscope apparatus according to claim 3, further comprising:
a display unit;
wherein the control unit controls the display unit to display a warning message when the amount of shake exceeds the predetermined amount.

### Claim 5 (depends on 4)

The endoscope apparatus according to claim 4, wherein the control unit controls the display unit to display the warning message with the first image.

### Claim 6 (depends on 3)

The endoscope apparatus according to claim 3, further comprising:
a display unit;
wherein the control unit controls the display unit to display a value of the amount of shake when the amount of shake exceeds the predetermined amount.

### Claim 7 (depends on 6)

The endoscope apparatus according to claim 6, wherein the control unit controls the display unit to display a warning message with the value of the amount of shake.
