Abstract: A method for estimating a temperature of a light emitting module having a plurality of light emitting elements is provided. The method includes, based on a lighting pattern of the light emitting module, which represents an intensity of light emitted from each of the light emitting elements, estimating respective temperatures of at least a part of the light emitting elements that are operated in accordance with the lighting pattern.

Abstract: In an image composer, an image input unit receives an image signal representative of the image of a subject, and outputs image data corresponding to the image signal to an expression feature extractor. The expression extractor extracts feature data representative of a facial expression contained in the image data. A follow processor reads out object data from an object storage, and performs a follow process on the read object data according to the feature data to feed the processed image data to an expression composer. The expression composer combines the fed image data with one of fed image data, for example, character image, to output image data representing a composite image.
