An imaging apparatus including a frame buffer executes high-speed shooting consecutively in plural sessions. An imaging element includes a buffer, an image producing unit, a managing unit, and an output unit. The image producing unit produces an image in the case where an empty capacity of any of plural areas in the buffer exceeds a predetermined threshold value. The managing unit causes an area whose empty capacity exceeds the predetermined threshold value, of the plural areas to retain the image as a buffering image. The output unit extracts the buffering image from the buffer and outputting the buffering image, in order of the retention of the buffering image.

The present disclosure relates to a signal transmission device, a signal transmission method, and a program that are capable of reducing the influence of a quantization error. A quantization error notification unit notifies the stage after a bit precision constraint region of a quantization error generated in a quantization processing unit that performs a quantization process on a signal to be transmitted via the bit precision constraint region that is a region where a bit precision constraint occurs. A quantization error reception unit receives the quantization error, and supplies the quantization error to an inverse quantization processing unit that performs an inverse quantization process on the signal transmitted via the bit precision constraint region. The present technology can be applied to an image signal transmission device that transmits image signals, for example.
