Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic endoscope apparatus for displaying image processing conditions, and more particularly to a structure for setting processing conditions for image signals obtained by the electronic endoscope.

[0002]

2. Description of the Related Art An electronic endoscope apparatus is provided with a CCD (Charge Coupled Device), which is a solid-state image sensor, at the tip of an endoscope, and a signal obtained by the CCD is subjected to image processing by a processor unit. , An image of the inside of the observed body is displayed on the monitor. In such an apparatus, the condition for processing the image signal obtained by the CCD in the process circuit can be set separately from the display condition of the monitor itself. That is, although the image signals obtained by the CCD differ depending on the frame sequential method, the simultaneous method, etc., these image signals undergo image processing such as amplification, gamma correction, and white balance. Therefore, it is possible to obtain an image that can be easily observed by individual operators (operators) by changing the processing conditions during this image processing.

Such image processing conditions include, for example, the level of each color of R (red), G (green), B (blue), the degree of detail display, etc., and the setting of these condition values is performed by the processor. This is performed by a volume knob or the like provided on the operation unit of the device or the like.

[0004]

However, in the above-mentioned conventional electronic endoscope apparatus, since the display processing condition is set by the volume knob or the like, there is a disadvantage that it is difficult to grasp the entire photographing condition. Further, the reference value (for example, 0 level) of the volume is set to a reference value in a general image, and for example, the reference values for the RGB color levels faithfully reproduce white in white balance. Since it is set as described above, the display is not necessarily easy to see as an image of an endoscope that mainly observes a reddish body cavity. Therefore, this reference value does not serve as a reference value for each condition of the display process, and there is a problem that it is difficult to set.

The present invention has been made in view of the above problems, and an object thereof is to grasp the entire display processing condition,
An object of the present invention is to provide an electronic endoscope apparatus that displays image processing conditions that enable display processing conditions to be set based on a reference value that is a reference for an endoscope.

[0006]

In order to achieve the above object, the present invention provides an electronic endoscope for displaying an image inside a body under observation on a monitor by processing an image signal obtained by an image pickup device. In the apparatus, a memory for storing an average image processing condition value of the endoscope operator is provided, and a plurality of condition values for the image processing are displayed as levels on the monitor and whether or not the condition value is reset is determined. It is characterized in that the average image processing condition value stored in the memory is displayed as a level when the above selection section is displayed and the reset is selected and executed on this monitor display screen.

[0007]

With the above arrangement, all of the image processing conditions are displayed on the monitor at once, for example, RGB
The level of each color and the master black level are indicated by numerical values on the scale, and the level of the detail is indicated by the low, medium and high level indications. A doctor who is an endoscope operator can arbitrarily set the processing condition value by operating the operation unit while observing the level display. When the execution of the reset displayed on this monitor is selected, the average image processing condition value of the doctor stored in the ROM is read out, and this condition value is replaced with the current level value. Is displayed. Therefore, the doctor, who is the operator, can easily set the conditions suitable for himself while referring to this average value.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of an electronic endoscope apparatus for displaying image processing conditions according to the embodiment, and FIG. 2 shows the display state of a monitor. In FIG. 1, a CCD 11 is arranged at the tip of an electronic endoscope 10 as a scope, and the electronic endoscope 10 is connected to a processor device 12. In the processor unit 12, the CCD 1
An image processing circuit 14 for inputting the image signal output from the image processing apparatus 1 is provided, and the circuit 14 performs processing such as amplification, gamma correction, and white balance on the image signal.

Further, a ROM 15, a RAM 16, a character generator 17, and a central processing unit (CPU) 18 are provided. The ROM 15 and the RAM 16 store various kinds of information necessary for image processing and display processing, and particularly ROM.
An average image processing condition value of a doctor who is an endoscope operator is stored in 15. As the image processing conditions, in the embodiment, master black (black gradation), R (red) color,
G (green) color, B (blue) color, detail (detail level) and the like are provided.

The character generator 17 generates a character such as a character used for displaying an image or a character under the image processing condition as shown in FIG. 2, and the CPU 18 controls the entire control and the image. Performs display processing related to processing conditions. That is, at the same time as the level display process of the image processing condition and the display process of the reset selection unit are performed, the cursor display process for selecting each level value is performed in the level display. This CPU18
An operation unit 20 including a keyboard or the like is connected to the interface, and an interface 21 is arranged between the control circuit and the image processing circuit 14. Furthermore, the processor device 1
A monitor 23 is connected to 2 in the form of inputting an image signal from the image processing circuit 14.

The embodiment has the above-mentioned structure, and the operation unit 20
By the operation of, the CPU 18 controls the RAM 16, the character generator 17, etc. to execute the display processing of the image processing conditions. Therefore, on the monitor 23, the image processing conditions are displayed in levels as shown in FIG. That is, as shown, for MASTER BLACK (master black), R LEVEL, G LEVEL, and B LEVEL, move the indicator bar above the linear scale, and the level value is indicated by the indicator bar, and DETAIL (detail ), Three-level characters of LOW, MID, and HIGH are displayed. In COLORBAR (for monitor color adjustment), the OF is displayed.
The characters F and ON are displayed, and the characters NO and YES are displayed in RESET (reset), and a shade or a surrounding frame indicating the selected state is superimposed on any of these characters. It should be noted that although these level values are set to the values currently set, all of the scale displays are 0 and DETAIL is MID at the time of factory shipment.

The level display of the image processing conditions is as follows:
It is displayed by being superimposed on the image inside the object to be observed or by utilizing the masked end area, and the display processing condition can be set while observing the image inside the object to be observed. That is, by operating the operation unit 20, the instruction bar, the surrounding frame, etc. are moved to the left and right to set the desired level value. In the level display of such processing condition value,
Since the whole is displayed collectively, there is an advantage that the setting is easy.

FIG. 3 shows the operation at the time of the reset operation. In the above display, when YES of RESET is selected and executed (step 101), the CPU 18
Reads out the average value of the doctor of the image processing condition from the ROM 15 and sets it (step 102). The average processing condition value is displayed on the monitor 23 in FIG. 2, for example, MASTER BLACK is 0, R LEVEL is +1, G LEVEL is 0, B LEVEL is -2, and DETAIL is MID. Therefore, the operator can set an optimum level value with the operation unit 20 while referring to this average level value, and a process for the individual operator to observe the inside of the reddish body cavity. The conditions can be set easily.
