Information processing apparatus for remote operation of an imaging apparatus and control method therefor
First Claim
1. An information processing apparatus which allows remote operation of an image capturing apparatus by communicating with the image capturing apparatus via a communication unit, the apparatus comprising:
- a display unit configured to continuously receive images from the image capturing apparatus and display the images as a moving image;
a reception unit configured to receive designation of an image area by a user with respect to an image displayed on said display unit;
a first calculation unit configured to calculate white balance information based on color information in the image area of the image displayed when said reception unit received the designation;
a determination unit configured to determine, based on color information of the image area on the image displayed when the designation was received and color information of image areas on a predetermined number of images received before the image, whether white balance information calculated by said first calculation unit is proper; and
an applying unit configured to apply white balance information calculated by said first calculation unit to the image capturing apparatus when said determination unit determines that the white balance information is proper,wherein if a ratio between the number of pixels, of pixels in the image area on any one of the images used for determination, which have pixel values falling outside a predetermined range and the total number of pixels in the image area exceeds a threshold, said determination unit determines that the white balance information calculated from the color information of the image area is not proper.

Abstract
An information processing apparatus receives images from the image capturing apparatus and displays them on a screen. The information processing apparatus then receives the designation of an image area by a user with respect to an image displayed on the screen, and calculates white balance information based on color information from the designated image area of the image displayed when the designation was received. The apparatus determines, based on the color information of the image area on the image displayed when the designation was received and the color information of image areas on a predetermined number of images received before the image, whether the white balance information to be calculated is proper. Upon determining that the information is proper, the apparatus applies the calculated white balance information to the image capturing apparatus. Upon determining that the information is not proper, the apparatus issues a corresponding warning.

6. A control method for an information processing apparatus which allows remote operation of an image capturing apparatus by communicating with the image capturing apparatus via a communication unit, the method comprising the steps of:
-
displaying images continuously received from the image capturing apparatus as a moving image; receiving designation of an image area by a user with respect to an image displayed in the displaying step; calculating white balance information based on color information in the image area of the image displayed when the designation was received in the receiving step; determining, based on color information of the image area on the image displayed when the designation was received and color information of image areas on a predetermined number of images received before the image, whether white balance information calculated in the calculating step is proper; and applying white balance information calculated in the calculating step to the image capturing apparatus when it is determined in the determining step that the white balance information is proper, wherein if a ratio between the number of pixels, of pixels in the image area on any one of the images used for determination, which have pixel values falling outside a predetermined range and the total number of pixels in the image area exceeds a threshold, it is determined in the determining step that the white balance information calculated from the color information of the image area is not proper.

7. An information processing apparatus which allows remote operation of an image capturing apparatus by communicating with the image capturing apparatus via a communication unit, the apparatus comprising:
-
a display unit configured to continuously receive images from the image capturing apparatus and display the images as a moving image; a reception unit configured to receive designation of an image area by a user with respect to an image displayed on said display unit; a first calculation unit configured to calculate white balance information based on color information in the image area of the image displayed when said reception unit received the designation; and an applying unit configured to apply white balance information calculated by said first calculation unit to the image capturing apparatus in a case that a ratio between the number of pixels, of pixels in the image area on any one of the image displayed when the designation was received and a predetermined number of images received before the image, which have pixel values falling outside a predetermined range and the total number of pixels in the image area does not exceed a threshold. - View Dependent Claims (8)
