Furthermore, when the two-point focus is set in step [86] (Y), the exposure is determined by enlarging the diaphragm in accordance with the positions of the two points in step [88]. The exposure is determined by using, for example, a table corresponding to the positions of two points. Then, in step [89], the aperture, shutter speed, etc. are set, and the process returns to step [78].

Therefore, in this apparatus, the photographed image is refreshed at regular intervals, and the text and the graphic are combined and displayed on the liquid crystal display 13. At the same time, the operation button 15 is detected as shown in FIG. 3, and when the buttons 15a to 15e are pressed, the mode is switched to each mode. In addition, zoom, focus adjustment, and exposure adjustment setting operations are also performed in parallel.

When the auto zoom button 15e is pressed, the auto zoom designation mode shown in FIG. 4 is entered. That is, first, the current position of the zoom lens is read, the movable range of the zoom lens is calculated, and if the zoom is close to the maximum, enlargement zoom cannot be performed. Therefore, a text sentence as shown in A of FIG. 10 is displayed, and the button detection routine is executed. Return.

When zooming is possible, a proper number of zoom frames are graphically displayed as shown in FIG. 10B, and the text sentence prompts the user to select a frame. When the touch panel 14 is touched and the frame is selected, the zoom lens position of the previously calculated magnification is stored and the auto mode is set.

On the other hand, in the zoom operation in FIG. 5, when the auto mode is set, the zoom lens is driven to the position determined in the auto zoom designation mode. For example, when the frame A is selected in B of FIG. 10, the image in the frame A is zoomed so as to fill the screen as shown in C of FIG. In the case of waiting for the touch panel in FIG. 4, the operation button 15 is detected until the touch panel 14 is touched, and if another operation button is pressed, that button is given priority.

Next, the partial focus mode includes one-point focus and two-point focus. The one-point focus refers to specifying one arbitrary point on the screen and focusing on it. In addition, the two-point focus means that when two points with slightly different distances from the camera are specified, the two points are focused at the same time.
The focus lens is moved so as to be in the middle of the points, and the diaphragm amount is increased according to the positions of the two focus lenses to increase the depth of field to facilitate focusing. When the partial focus area is not designated, for example, the central focus is set and the default image area is set.

When the partial focus button 15d is pressed, the mode is switched to the partial focus area designation mode shown in FIG. 6, the focus is set to one point, and the text is displayed as shown in A of FIG. When the partial focus button 15d is pressed for a certain period of time and the touch panel or other buttons are not pressed, and the partial focus button 15d is pressed again, the one-point focus is the two-point focus, and the two-point focus is the two-point focus. Is replaced with a one-point focus, and when the one-point focus is shown in FIG.
Text similar to is displayed.

Further, in the case of one-point focusing, when the point to be focused is designated on the touch panel 14 in the state of A of FIG. 11, a circle is graphically displayed at the designated point as shown in B of the same figure, and the focus area is set. For example, 50 pixels in the vertical direction and 50 pixels in the horizontal direction are stored around the designated place, and the operation button and the touch panel are returned to the standby state. In the one-point focus, the focus point can be changed by touching the touch panel 14 again.

The method of designating the two-point focus is shown in FIG.
When the point to be focused in the state of C is designated on the touch panel 14, the first point is designated, and a circle is graphically displayed at the designated position as shown in D of FIG. For example, 50 pixels in the vertical direction and 50 pixels in the horizontal direction are stored around the designated place, and the operation buttons and the touch panel return to the standby state.

At this time, the text sentence is displayed to instruct the second point. When the second point is instructed on the touch panel 14, the circles are placed at the first and second points as shown in E of FIG. Is displayed, the installation value of the second focus area is stored, for example, 50 pixels in the vertical direction and 50 pixels in the horizontal direction, with the specified location as the center, and the focus area specification mode is exited. It should be noted that while waiting for the touch panel, the operation button 15 is detected until the touch panel 14 is touched, and if another operation button is pressed, that button is given priority. Further, the text and graphic displays are kept as they are until any operation button is pressed.

On the other hand, the focusing operation is shown in FIG. In the one-point focus, the image data of the focus area designated by the partial focus area designation mode or the default value is cut out from the image memory, read into the memory 17, and the data is sent to the focus detection circuit 18 to determine the focus, and the focus must be in focus. For example, focus is adjusted by repeating a loop of moving the position of the focus lens.

In the case of two-point focus, the focus is adjusted by the image data of the focus area designated by the first point, and the position of the focus lens at this time is stored. Next, focusing is performed according to the image data of the focus area designated by the second point. Then, from the position of the focus lens and the position of the first focus lens at this time, the position where the focus is in the middle of the two points is calculated.

Then, the focus lens is moved to an intermediate position between the two focus positions, and at the time of exposure adjustment described later,
The diaphragm is enlarged according to the positions of the two focus lenses. It should be noted that in the two-point focus, the feedback is not applied, so that the two points may not always be properly focused, but it is determined by the photographer by looking at the image on the liquid crystal display 13.

Further, photometry includes average photometry and weighted photometry. The average photometry is to determine the exposure by measuring the average light quantity of the image data in the designated photometry area. The priority photometry is a method of determining the exposure from the average light intensity of the weighted image data in the photometric area and the light intensity of all the image data. If the area is not specified for partial photometry, for example, multi-pattern photometry is performed, and the exposure is obtained from the photometric data of a plurality of predetermined areas.

When the partial photometry button 15c is pressed, the partial photometry area designation mode shown in FIG. 8 is entered, and the screen as shown in A of FIG. 12 is initially displayed and the average photometry is set.
When the partial metering button 15c is pressed for a certain period of time and the touch panel or another button is not pressed, the partial metering button 15c is pressed again. When the average metering is switched to
In the case of 2A, and in the case of priority photometry, a text like B in the figure is displayed.

The partial photometric area is rectangular and is specified by two diagonal corners. That is, when one of the rectangular corners of the photometric area is designated by the touch panel 14 in the state of A of FIG. 12 or the state of B of FIG. 12, a circle is graphically displayed at the designated portion of C of FIG. You will be prompted to instruct. Here, when the diagonal corner is designated on the touch panel 14, a screen as shown by D in the figure is displayed, indicating that one photometric area can be designated.

It is possible to specify a plurality of photometric areas by repeating the same operation. E in the figure is a screen when the first corner of the second area is designated, and F in the figure is a screen when the diagonal corner of the second area is designated.
It should be noted that while waiting for the touch panel, the operation button 15 is detected until the touch panel 14 is touched, and if another operation button is pressed, that button is given priority.

On the other hand, the operation of exposure adjustment is shown in FIG. In this figure, first, the photometric mode is determined, the specified image is cut out from the image memory according to each photometric mode, read into the memory 17, and the photometric circuit 19 processes the data to determine the exposure. When the above-mentioned two-point focus is designated at the time of determining the exposure, the aperture is enlarged in accordance with the two focus positions obtained at the time of focusing, and the exposure is determined by obtaining the shutter speed.
After the exposure is decided, set the aperture and shutter speed.

In this way, according to the above-mentioned device, since the operation instruction is given using the touch panel 14, it is possible to perform focusing and photometry in a portion other than the center of the screen very easily.

In the above-mentioned apparatus, the setting of the auto zoom may be designated at two diagonal corners, like the designation of the photometric area. In that case, if so-called electronic zoom is used, an arbitrary portion on the screen can be zoomed. It should be noted that the electronic zoom is not preferable at present because it causes deterioration of image quality.

Further, in the above-mentioned device, the operation button 15 can be provided in the touch panel 14 by preparing a graphic for it.

[0074]

According to the present invention, since the operation instruction is given using the touch panel, it becomes possible to perform focusing and photometry in a portion other than the center of the screen very easily.
