Abstract: In a digital camera 4, when a shot image is chosen, fractal data expressing structural features of object images in the photographed image is obtained. The fractal data is sent to a search server 2.

Abstract: A plurality of preliminary image signals is acquired by carrying out preliminary image acquisition of a subject, before actual image acquisition, with different amounts of light received by an image acquisition device. Subsequently, a dynamic range and an amount of noise, or an S/N ratio, for a case in which the plurality of preliminary image signals is combined is calculated, and a received-light-level difference of the image acquisition device among a plurality of actual image signals acquired through the actual image acquisition is calculated on the basis of the dynamic range and the amount of noise, or the S/N ratio. Then, by carrying out the actual image acquisition on the basis of the calculated received-light-level difference, a plurality of actual image signals with different received light level is acquired. These actual image signals are combined to acquire a combined image.

Abstract: The present invention aims at obtaining a high-quality video signal by reducing tone jumps. A second grayscale conversion characteristic is calculated from a video signal to which a first grayscale conversion process has been applied using a first grayscale conversion characteristic used to convert an M-bit video signal into an N-bit video signal, where M and N are integers and M is larger than N. The first grayscale conversion characteristic is corrected by using the second grayscale conversion characteristic. The first grayscale conversion process is applied to the video signal by using the corrected first grayscale conversion characteristic.
