Embodiment Construction

[0045] image 3 It is a schematic structural diagram of a camera device based on an SPI interface according to an embodiment of the present invention. In this embodiment, the camera device based on the SPI interface includes a baseband chip 10, an image sensor 20, and a liquid crystal display 30. The image sensor 20 is a data sending device, the liquid crystal display 30 is a data receiving device, and the baseband chip can either receive data or send data. In the preview mode, the image data is output by the image sensor 20, and the liquid crystal display 30 receives and displays the image data. The baseband chip 10 does not receive the image data but only sends parameter settings for controlling the display of the liquid crystal display 30 through the SPI bus. In the photographing mode, the liquid crystal display 30 is turned off, and the image data output by the image sensor 20 is received by the baseband chip 10.

[0046] The baseband chip 10 can be used to determine whether...

Abstract

The invention discloses an image data transmission method and photographic equipment based on a serial peripheral interface (SPI). The method comprises the following steps: S1, judging whether a baseband chip enters into a preview mode or photographing mode in accordance with a user operational order; if entering into the preview mode, executing the S2; and if entering into the photographing mode, executing the S3; S2, receiving a frame synchronizing signal by the baseband chip from an image sensor, and controlling the chip selection of the liquid crystal display through interruption to cause a liquid crystal displsay (LCD) to synchronously receive image data from the image sensor for displaying through an SIP bus; and S3, receiving an output enable signal by the baseband chip from the image sensor and receiving the image data from the image sensor through the SPI bus, and compressing the image data into pictures for storage. The interruption detection control LCDCS is utilized to carry out timing sequence matching control and the functions of the image sensor are utilized sufficiently. A photographic function is realized on an ultra-low end hardware platform based on the SPI, thus enlarging the applied range of the photographic equipment.

Description

Technical field [0001] The invention relates to the field of image data transmission and photographing equipment, in particular to an image data transmission method and photographing equipment based on an SPI interface. Background technique [0002] Nowadays, wireless communication technology is widely used in people's daily life, and mobile phone terminals are also popularized due to their convenience. With economic development and technological progress, people's living standards have greatly improved, and low-end mobile phone terminal multimedia technology has been unable to meet people's needs, and multimedia phones with camera functions are becoming more and more popular. [0003] figure 1 It is a schematic diagram of the connection between the image sensor and the baseband chip in the prior art. figure 2 It is a schematic diagram of the structure of the camera equipment in the prior art. The baseband chips in these two pictures are all described with MT6223C as an example. ...
