Abstract

An image sensor module is provided. The image sensor module includes a printed circuit board (PCB), an image sensor chip disposed on a first plane of the PCB and electrically connected to the PCB, and an image signal processing chip disposed on the first plane of the PCB and electrically connected to the PCB. An aspect ratio of the image signal processing chip is at least two times greater than an aspect ratio of the image sensor chip. A minimum feature size of a metal line implemented in the image sensor chip is at least 1.5 times greater than a minimum feature size of a metal line implemented in the image signal processing chip.

Claims16

Dependent claims

An image sensor chip comprising:

a pixel array;
a timing generator configured to generate a first horizontal synchronization signal and a first vertical synchronization signal whose respective horizontal and vertical blanking periods have been adjusted according to digital zoom ratio information;
and
an output circuit configured to output a data signal corresponding to a zoom region among data signals corresponding to signals output from the pixel array according to the first vertical synchronization signal and the first horizontal synchronization signal,
wherein the timing generator increases the horizontal blanking period and simultaneously decreases the vertical blanking period according to the digital zoom ratio information, and
wherein the timing generator comprises:
a register configured to store the digital zoom ratio information;
an address generator configured to output addresses for selecting pixels corresponding to the zoom region in the pixel array;
a synchronization signal generator configured to generate the first horizontal synchronization signal and the first vertical synchronization signal;
a main control unit configured to control an operation of the address generator and an operation of the synchronization signal generator according to the digital zoom ratio information stored in the register;
and
a control unit configured to control the output circuit to output the data signal corresponding to the zoom region according to the digital zoom ratio information stored in the register.
