Method of processing data, and photographing apparatus using the method
First Claim
1. A method of data processing in a surveillance camera which comprises an image sensor and a hardware signal processor, the method comprising:
- controlling the hardware signal processor to determine a file format, in which data output from the image sensor is to be recorded in a file, among a plurality of file formats comprising a dedicated file format and a common file format; and
in response to the file format being determined as the common file format, controlling the hardware signal processor to record the data in a file of the common file format, generate an auxiliary file of the dedicated file format, and record, in the auxiliary file, information about the dedicated file format and recording information required for reading the data recorded in the file of the common file format, the recording information comprising an index value and an offset position value of the data in the file of the common file format; and
controlling the hardware signal processor to extract a data unit of the data recorded in the file of the common file format by using the recording information in the auxiliary file of the dedicated file format, extract the information recorded in the auxiliary file of the dedicated file format, and stream the file by alternately transmitting the data unit and the information through a network to a receiver operating according to a dedicated program corresponding to the dedicated file format,wherein the file of the common file format and the auxiliary file of the dedicated file format are recorded in a memory of the surveillance camera which obtains the data, andwherein the dedicated file format is a format where frame headers and the data are alternately disposed, each of the frame headers containing same information.

7. A surveillance camera comprising:
-
an image sensor configured to output data corresponding to at least a captured image; and a hardware signal processor configured to determine a file format, in which the data is to be recorded in a file, among a plurality of file formats comprising a dedicated file format and a common file format, wherein, in response to the file format being determined as the common file format, the hardware signal processor is configured to record the data in a file of the common file format, generate an auxiliary file of the dedicated file format, and record, in the auxiliary file, information about the dedicated file format and recording information required for reading the data recorded in the file of the common file format, the recording information comprising an index value and an offset position value of the data in the file of the common file format, and wherein the hardware signal processor is further configured to extract a data unit of the data recorded in the file of the common file format by using the recording information in the auxiliary file of the dedicated file format, extract the information recorded in the auxiliary file of the dedicated file format, and stream the file by alternately transmitting the data unit and the information through a network to a receiver operating according to a dedicated program corresponding to the dedicated file format, wherein the file of the common file format and the auxiliary file of the dedicated file format are recorded in a memory of the surveillance camera which obtains the data, and wherein the dedicated file format is a format where frame headers and the data are alternately disposed, each of the frame headers containing same information. - View Dependent Claims (8, 9, 10, 11, 12, 14)
