Description

  The present invention relates to a vibration feedback control method and a control apparatus.

  In an input device using a capacitance sensor such as a touch panel in a camera, the change in the set value due to the slide operation has no click feeling, so the change in the set value cannot be felt and the operation continues and deviates from the intended set value. There is a case.

  In recent years, as means for solving the problem that the operation deviates from the intended set value, it is known as an effective means to replace the click feeling of the button to transmit feedback by vibration according to the operation of the touch panel.

  Further, as described in Patent Document 1, it is possible to easily know what the current set value is by changing the amplitude and cycle of vibration according to the position of the operation.

JP 2010-128526 A

  In the solution described in Patent Document 1, the amplitude and period of vibration are determined according to the range of the touch panel. However, when considering camera setting values related to image quality, the image quality corresponding to the setting value depends on the subject and the surrounding environment. The superiority or inferiority of the company always changes.

  For example, taking a zoom setting value as an example, switching between optical zoom and digital zoom is a range of setting values that affect image quality.

  If ISO, the amount of noise generated is within the allowable range from the viewpoint of image quality, and the range of ISO sensitivity that is effective during normal use is defined as regular ISO. The range of ISO sensitivity is defined as extended ISO, and switching between regular ISO and extended ISO is a range of setting values that affect image quality.

  When the set values of Tv, Av, and ISO are manipulated, the range exceeding the low brightness limit or the high brightness limit is the set value range that affects the image quality.

  The above setting values are not uniquely determined according to the range of the touch panel as in Patent Document 1.

  In the conventional method, it is possible for the user to know the change in the setting by transmitting feedback by vibration according to the operation, but it is easy to know whether the change in the setting is a change that adversely affects the image quality. I can't.

  In the present invention, in the vibration feedback sensor, by changing the frequency of vibration and the strength of vibration, when an operation exceeding the set value range that affects the image quality is performed, the user is emphasized and notified.

  Taking the zoom setting value as an example, switching between the optical zoom and the digital zoom is a range of setting values that affect the image quality. Therefore, vibration feedback is performed with emphasis when switching between the optical zoom and the digital zoom and when operating with the digital zoom.

  Taking ISO as an example, switching between the regular ISO and the extended ISO is a range of setting values that affect the image quality. Therefore, vibration feedback is emphasized when switching between the regular ISO and the extended ISO and when operating in the extended ISO.

  Taking the setting values of Tv, Av, and ISO as examples, it is necessary to evaluate the exposure value based on the photometric calculation result in order to determine whether or not the setting value is within a range that affects the image quality. As a result, the range exceeding the low luminance limit or the high luminance limit is a set value range that affects the image quality. Therefore, the emphasized vibration feedback is performed in the case of the set value affecting the image quality.

  In other words, it emphasizes that the user has overcome the threshold that affects image quality by changing the frequency or strength of vibration when exceeding the range that affects image quality, depending on the type of setting value currently being operated. By performing vibration feedback, it is possible to easily know that the user is operating the set value within a range that does not affect the image quality.

  According to the present invention, it is possible to “simply know that the set value is operated within a range that does not affect the image quality”.
