An imaging apparatus wherein a captured image is subjected to a rotational transform so as to correct the inclination of one or more subjects in the captured image. The imaging apparatus defines, with reference to a physical inclination detected by a sensor, an angle range in which the image is to be processed. The imaging apparatus then processes the captured image and detects lines therein and inclination angles thereof. The imaging apparatus then creates histograms indicative of frequency distributions of the inclination angles of those lines, and selects, in the created histograms, an inclination angle having a frequency that satisfies a predetermined criterion, as a rotational angle to be used for the rotational transform.

A wearable terminal is constantly worn by a user and continually picks up images and sounds from the surroundings. Even when using a directional microphone to sensitively pick up targeted audio, the wearable terminal can reduce noise occurring due to motion of the device, for example when the user is walking, and reduce the influence of a shift of the sound pickup direction. For this purpose, the wearable terminal includes a sensor for detecting motion, and performs microphone directivity control to use the directional microphone when the amount of motion is small, and to use an omnidirectional microphone that is not likely to be influenced by noise when the amount of motion is large.

The present invention implements a method and an apparatus for retrieving a sound data desired by the user on the basis of its subjective impression over the sound data. The subjective impression on the desired sound data is entered by the user and converted to a numerical value. A target sound impression value which is a numerical form of the impression on the sound data is calculated from the numerical value. The target sound impression value is then used as a retrieving key for accessing a sound database where the audio signal and the sound features of a plurality of the sound data are stored. This allows the desired sound data to be retrieved on the basis of the subjective impression of the user on the sound data.
